▼ Abstract: A Pressurized water Reactor core can be described as a large heat exchanger composed of nuclear fuel rods assembled vertically in a regular geometric pattern. The rods are grouped in units called fuel elements, being held in position by spacer grids and end pieces at both ends. Water enters the core driven by the bottom end pieces trough a perforated plate. The Industrias Nucleares do Brasil (INB), as the main supplier of fuel elements for the Brazilian nuclear power plants, works continually for its improvement. One of the most important developments is a bottom end piece that can filter debris with the purpose to avoid damage to the fuel rods. One of the alternatives is the use of perforated plates with small diameter holes. This causes an increase in the pressure drop. In order to reduce this effect an optimization of the geometry of the holes must be performed. This has traditionally been carried out by experimental tests which are expensive and difficult to perform. An alternative increasingly used is the numerical simulations of the flow by the Computational Fluid Dynamics (CFD) technique. This work presents and validates a numerical simulation procedure that uses the commercial CFD code ANSYS CFX for the estimation of the pressure drop of water flowing through perforated plates similar to the ones of the current and advanced INB bottom end pieces. The validation was performed by using the procedure to simulate reduce scale experiments. The goal was to estimate an uncertainty range for applying the procedure. Two different validation methodologies were applied and compared. At the end the procedure was used for an evaluation of the influence of the hole geometry on the pressure drop Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Jordão, Elizabete, 1956- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Enzymes such as lipase has been widely used in the treatment of effluents with a high content of lipids such as those generated by the food industries. The lipase production by microorganism such as yeast Yarrowia lipolytica in culture media with the use of agro-industrial waste can promote an increase in expression of the enzyme activity, and represents a viable economic alternative to mitigate environmental impacts caused by the accumulation and disposal these wastes into the environment. In this perspective, the whey is a nutritional low-cost alternative for the production of lipases by microorganisms. In this work, the production of lipases in Y. lipolytica on alternate means was investigated with use of whey and the development and characterization of a bioproduct with lipase activity to be used in the treatment of dairy effluent (whey). The analysis of the influence of factors: pH, temperature, substrates (whey and olive oil), stabilizers (glycerol and Triton X-100) and time, were made by successive experimental designs having as variables response to the production and characterization of stability of the enzyme lipase. For the formulation of the bioproduct with lipase activity metabolic liquid was concentrated by an ultrafiltration process and then subjected to the stabilization process. Research on analysis of effluent degradation was carried out through a factorial design to evaluate the effect of formulated bioproduct and a commercial compound nutrient in the period of 48 hours on response variables reduced lipid content, COD and BOD. The results of the production of the lipase enzyme demonstrate that greater production of lipases (172 U/mL) occurred in medium composed of 80% of whey in the absence of olive oil and pH 6.0 for 120 hours of cultivation. The ultrafiltration process used for the concentration of bioproduct enabled an increase in lipase activity to 235 U/mL. On the other hand, significant results on the maximum stability of the lipase activity of 420 U/ mL and 398 U/mL, respectively were determined after storage for 22 and 32 days of bioproduct formulated in the presence of glycerol and 6.0 % of the surfactant Triton X-100 0.1 %. The characterization for stability formulated bioproduct observed the optimum pH to 4.5 and 7.0 keeping 82 % of its activity after 90 minutes incubation temperature and it was found that after 90 minutes incubation at 60 0C the retention of lipase activity of 94%. The preparation lipásico formulated to have elevated rates of hydrolysis for the treatment of dairy effluent whey. The parameters of the COD, BOD and effluent lipids used for evaluating the efficiency of treatment showed that the formulated bioproduct produced a significant reduction in these parameters showing efficiency exceeding 90%. Thus, the results on the stability of formulated bioproduct and treatment the dairy effluent indicate its potential for biotechnological applications Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Salgueiro, Alexandra Amorim (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: Numerous chemical and petrochemical processes in industrial operations utilize mechanical impellers in tanks. In almost all of these processes heat transfer devices for heating or cooling are in place and their agitation can be achieved by the use of various types of impellers that yield many forms of fluid movements. Consequently, the kind of contact with the heat transfer device also occurs differently. There is a lack of literature to obtain information on parameters when projecting heat transfer tanks with spiral coils placed on the bottom of the tank whose agitation is made by radial and axial impellers in a steady state operation. The present work aimed at determining parameters of Nusselt's equation experimentally in tanks with radial and axial mechanical impellers and spiral coils placed on the bottom using water and sucrose at a concentration of 50%. The experimental rig was made of an acrylic tank with a 50 liter capacity, a spiral copper coil, radial and axial mechanical impellers and a 3 HP electric motor. The heating fluid was water and the cool fluids were water and sucrose. Rotations between 90 and 330 rpm were used. All the trials were run until the exit temperatures of the cool and hot fluids stabilized, that is, until they reached a steady operation. The results showed that the models for the Nusselt equation achieved a reliability of 95,5% and 93,6% for the radial and axial impellers respectively. A comparison was made of the models obtained in the current work to the proposed models of the tube baffles with similar heating conditions. In what concerns the axial impeller, by using the spiral coils heat transfer is more efficient. However, when using the radial impeller at a Reynolds interval between 2000 and 5000 the tube baffles revealed a better fluid heating. Furthermore, at Reynolds above 50000 the spiral coil obtained a more efficient heat transfer Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The potential of these compounds surfactants produced from microorganisms is based on their functional properties, which include emulsification, separation, wetting, solubilizing, demulsification, corrosion inhibition, reduced viscosity and liquid surface tension reduction. This study aimed to evaluate the production of biosurfactant by strain of Pantoea sp. Using corn steep liquor, juice from the pineapple peel and post-frying vegetable fat feedstock unconventional. In trials with Pantoea sp. in shaker table, assessed the minimum optimum concentrations of substrates by rotational central composite design (CCRD) computer program. The results indicated that the minimum optimal concentrations of the substrates were 2% (v / v) vegetable fat, 5% (v / v) of corn steep liquor and 25.0% pineapple juice from hulls. It showed the highest reduction in surface tension (30.0 mN m) and a yield of 2.8 g / L. In these tests, we observed a high cell growth, achieving an optical density (at 600nm) of 5.0 to 48 h of cultivation. Based on the results of the optimization carried out in table shaker, the medium was selected for studies in bench fermentor. Assays were performed using a bioreactor at 30 ° C, 350 rpm and 0.5vvm aeration, it was observed, the profile of production of the biosurfactant. Was accompanied by the thermal stability, effect of variation of pH and NaCl concentration, the surface tension of the biosurfactant produced and its chemical composition.

▼ Abstract: Ionic liquids are considered less environmental impact solvents, especially for their low vapor pressure. The goal of this work was to determine liquid liquid equilibrium (LLE) data of ternary systems with ionic liquid + water / methanol / ethanol + methyl / ethyl / propyl acetate at 25 ?C. In this work ionic liquids are protic, with simple synthesis, and were produced in our laboratory. The measurement of properties (density and refractive index) at each cloud point was the technique used to determine the calibration curves at methanol and ethanol systems and water systems, the measurement property technique was complemented by segment extrapolations between feed point and ionic liquid rich phase, through acetate phase direction. Ionic liquids are environmentally friend solvents because of their low vapor pressure. The FT-IR and RMN analysis were used for verifying the liquid salt formation. After the intended product was formation, some important industry properties were determined. Also solvent + solute molar volume were determined aiming to verify these binary mixture volumetric behavior.

In water and ethanol systems the three ionic liquids presented close extraction capacities, while methanol systems the lower chain ionic liquid, 2-HEAB, presented higher extraction capacity.

▼ Abstract: Bromelain is the generic name given to endopeptidases set coming from the members of the Bromeliaceae family, which owns the pineapple (Ananas comosus) and curauá (Pineapple erectifolius). Due to the important physiological roles they play, these enzymes provide a broad spectrum of proven therapeutic applications (anti-inflammatory action, anti-tumour, adjunct in wound healing, increase in cardiac capacity, etc.), and are used by the food industry in meat processing. The study bromelain extraction from organic residues (produced during the processing of pineapple), using aqueous two-phase systems (ATPS) offers a potential alternative to its purification and production. Additionally, annular centrifugal extractors are little studied equipment in Brazil, but that offer performance and efficiency higher than those obtained with conventional equipment. Thus, studies that aim to purify the bromelain from waste, using methods and processes, unusual and with the objective of marketing for the pharmaceutical industry are highly promising scientific and technological point of view. This work focuses on studying and development of a variant of the puller able to obtain bromelain by use of ATPS in the processing of waste referred to through the use of computational fluid dynamics (CFD) tools. Both the optimization of the ATPS as simulation process itself required the use of experimental design, as well as tools that aids have been developed throughout the project. As a result, it was possible to obtain bromelain with purity of commercial samples available and build a prototype extractor studied using widely known composite materials Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Campos, Edgar Silveira (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: Pollution of water resources is one of the main factors that reduces the availability of fresh water and increases the use of advanced treatment techniques. This paper discusses the use of an adsorbent material produced through fast pyrolysis and chemical activation with sodium hydroxide (activated charcoal) and without thermal treatment (in natura) from the fruits of Casuarina equisetifolia for advanced water treatment and oily wastewater by adsorption, providing an effluent suitable to final disposal or reuse. The adsorption isotherms were obtained by varying the temperature and the mass of bioadsorbent, and comparing its adsorptive capacity with other vegetal adsorbents, among them a commercial product. Moreover, the economicity of the process was evaluated after adsortion curing (desorption) of the adsorbent, which was shown to be efficient in this sense with 89% adsortion. To evaluate the actived charcoal behavior in face of the adsorption process, the adsorbent process was characterized and compared to the actived charcoal. The techniques employed were the X-ray diffraction (DRX), scanning electron microscopy (MEV), nitrogen physisorption through the BET method, thermogravimetry (TG), differential thermal analysis (DTA), spectroscopy in the infrared region (FT-IR) and surface charge determination (pHzpc). It was also developed a statistical analysis for process optimization. The bioadsorbent in natura showed greater adsorption capacity than the activated carbon, under the same experimental conditions, revealing that it has a good potential to be used as an adsorbent for water and wastewater treatment by adsorption Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Marques, Jose Jailton (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The contact between solids and liquids in tanks with mechanical impellers are involved in about 80% of the operations in chemical and mineral industries, including processes ranging from leaching and complete dissolution of reagents to suspension of catalysts and reaction products, such as precipitates and crystals (KUZMANIC; RUSIC, 1999). It is not convenient to carry out the studies of optimized suspension at tanks in industrial scale. The present study was done to verify seven scale up methods of tanks with mechanical impellers, analyzing the axial profile of solids concentrations and axle power consumption. The experimental units are comprised of two acrylic cylindrical tanks of similar geometry, measuring 0,010m3 and 0,049m3 and coarse particles (-48+65#) of apatite ore. Turbine of 2 or 4 blades inclined at 45° and Rushton turbine were used. Proposed by Zwietering (1958) the impeller minimum rotation (Njs) was adopted. The control variable where the maximum standard deviation was ± 0,4 rps. It was observed that the axial profiles of solids (apatite ore) distribution were similar for the two tanks under study and the trials were carried out in isokinetic conditions. The values found for the power numbers (Np ± 1,40) and for the Njs are close to the values reported in current literature. For the impeller an exponent value of n equal to 0,75 for the ratio between rotation (N) and impeller diameter (D) called n, where N2=N1.(D1/D2)n, in agreement with recommendations by Rautzen et al (1976). The small devitations for techniques of other impellers were: a) 2 inclined blades at 45°, Power per Constant volume (2% devitation) with n of 0,67 e b) turbine with 6 flat blades 90°, (8% devitation) with the same expoent n de 0,67 Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The release of dense fluid in an environment with less dense fluid on a surface generates a flow structure named a gravity current, caracterised a high region at the forehead, named head, followed by a stratified dense layer named tail. The understanding of the fluid mixing mechanism is of great importance, either for understanding nature as well as for engineering applications. This work aims to understand the mechanism of mixing and quantify the rate of dilution between fluids in gravity currents. In this work, firstly it was performed numerical simulations of real cases of dense gas dispersion using the noncommercial computational fluid dynamic (CFD) package OpenFOAM, specifically the rhoReactingBuoyantFoam solver. Comparison of numerical results with experimental data demonstrated the potential of the software, as well as limitations regarding the accuracy of time (in transient cases) and gas concentration in far field regions. Subsequently, a series of experiments were performed, these consisted of generating gravity currents in the laboratory by continuously pump saline solution on a sloped surface (5?) into a tank filled with water. Food dye was used to allow visualising and capturing of images by the Nikon D90 camera. The images were processed using MATLAB software and the light attenuation technique was applied to obtain density distribution within the flow structure. It has been observed that there is mixture between the fluids in all gravity current regions, near the source of release, tail and head. Each of these regions were studied separately and dilution values were obtained as a function of the flow properties. With these parameters, a semi-empirical model was developed to predict the volume of the gravity current as a function of time. Finally, numerical simulation of the experiments was performed using OpenFOAM solvers with compressible (rhoReactingBuoyantFoam) and incompressible (twoLiquidMixingFoam) models using RANS (Reynolds Averaged NavierStokes) approach...

▼ Abstract: The curaua (Ananas erectifolius LB Smith) is a herbaceous plant species, belonging to the family Bromeliaceae, native to northern Brazil, especially the Amazon, where it can be extracted bromelain. This enzyme is part of a group of proteolytic enzymes, used in the food industry and as a medicine, it offers wide range of therapeutic efficacies: antiedemas, anti-inflammatory, antithrombotic and fibrinolytic activities. The development of new extraction and purification of proteins is very important, since this is a limiting step in the production of bioproducts. A major challenge is in getting the bromelain enzyme maintain its stability during the extraction, purification, drying and storage. Therefore, studies are being conducted to identify mechanisms that lead to protein denaturation, and thus pointing ways to minimize this inactivation. Thus, the determination of enzyme activity in plants may provide indicative curaua for further purification and thus contribute to the optimization of this specie, since the main product of the fiber is extracted, and the other components are currently discarded. The characterization results showed that the ideal working conditions are pH 6 and temperature at 40°C and 60°C for the white variety, and pH 6 and 7 and 40°C temperature for the purple variety. The molar mass is 24 kDa, and better stability condition with the highest activity at pH 6 and temperature between 20 and 40°C for both curauá purple, and for the white, the latter being more stable. The kinetic parameters showed that curauá purple has a lower Km value with 158.73 ?mol.L -1min and white 185.18 ?mol.L-1 min. With both varieties, affinity for the substrate used in the experiments, azocasein was demonstrated. The white curaua showed lower activation energy, demonstrating that the better enzyme activity compared to purple curaua and other proteases. These results showed significant amounts of activity, activation energy and stability when compared with other proteolytic enzymes, confirming that this is a complex enzymatic with hydrolytic activity Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: One phase thermally stratified flows occur when two different layers of the same liquid at different temperatures flow separately in horizontal pipes without appreciable mixing due to the low velocities and difference in density (and temperature). The phenomenon was not considered in the design stage of most of the operating nuclear power plants. However, temperature differences of about 200 °C have been found in a narrow band around the hot and cold water interface in components under stratified flows. Loadings due to this phenomenon affected the integrity of safety related piping systems. The Thermal Stratification Test Facility (ITET), built to allow the experimental simulation of the thermal stratification, is presented so as the results of some experiments simulating one phase thermally stratified flows in geometry and flow condition similar to a nuclear reactor steam generator nozzle. They have the objective of studying the flow configurations and understanding the evolution of the of thermal stratification process. The driving parameter considered to characterize flow under stratified regime due to difference in specific masses is the Froude number. Different Froude numbers, from 0.02 to 0.4, were obtained in different testes by setting injection cold water flow rates and hot water initial temperatures as planned in the test matrix. Results are presented showing the influence of Froude number on the hot and cold water interface position, temperature gradients and striping phenomenon...Note: The complete abstract is available with the full electronic document Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Jordão, Elizabete, 1956- (advisor), Navarro, Moysés Alberto (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The displacement of polymers, pharmaceutical cereals, ores, pharmaceutical products and other particulate materials in the interior of tubing , having as fluid transporter the air, is called pneumatic transport. This technique is commonly divided in: transport in dense phase, with particles concentration above 30% in volume and transport in diluted phase, with inferior concentration at 1%. The diluted phase, that does not demand thick tubing and is acquired at lesser cost operation and maintenance, has as main inconveniences: a) the consuming of the inferior part of the transporting pipe due to bad distribution of particles in the transversal session; b) the lack of data of the loss of load of T with side exit, that has been replacing curves in catalytic units of oil for creating a cushioning mattress and reducing consuming and c) the scarcity of information of the relation between the particle distribution in the transversal section of the duct and the loading loss. The present work had as general objective to project and build up an experimental unit, in scale pilot with a 117 mm diameter duct, of pneumatic transport to study, in diluted phase, the losses of load in the vertical stretch, the particle singularities and distribution in the transversal section. It aimed as specific objective: a) to construct the curves of loss of load in function of the air speed, having as parameter, the outflows of pellets of polypropylene; b) to determine the value of coefficient K, multiplier of the kinetic load of the general expression of loss of located load for T with side exit, with three distinct prolongations (boundary-makers): 30, 60 and 90 mm and c) to get the distribution of particles in the transversal section of the vertical duct. The projected and built unit consisted basically on a centrifugal fan, with opened half 210 mm diameter shovels, connected to a 1cv changeable rotation engine, a pipe of horizontal Pitot and one vertical line, a rotating valve set in motion by engine of changeable rotation in the base of a feeding silo, extruded acrylic ducts, with internal diameter of 117 mm, a system of collection with nine ducts, square shaped section parallel, for analysis of the distribution of particles in the transversal section of the horizontal and vertical ducts and a cyclone. The loss of load was determined through static pressure heads, connected to piezometric surface rings, with simultaneous reading of all the pressure heads in a series of pipes in "U". The air speed was gotten by Pitot and anemometers. The volumetric outflow of air was calculated by the method of the centroids of equal areas, with the measures of the values collected by the Pitot and anemometer. The outflows of particulates solids were quantified by the number of revolutions per unit of time of the rotating valve, surveyed by the technique of the mass per time. The particle distribution, in the transversal section of the vertical and horizontal pipes and after T with side exit, was verified by weighing solids in the collectors.

▼ Abstract: In this work was investigate the physical-chemical treatment for the removal Remazol Black B dye reagent by adsorption using chitin isolated from industrial waste (exoskeleton shrimp). The extraction of chitin was made from industrial waste of shrimp (exoskeleton of shrimp) in the decolorization treatment with NaClO, followed by deproteinization of alkali solution at temperature of 1000C, and freeze dried. The chitin were separated by granulometry corresponding to fraction mesh 16. The removal process of Remazol Black B dye was used a new method applying the technique of adsorption with subsequent ligation with inorganic and organic mordants solutions, in order to enhance and improve the fixing of dye hydrolyzate. A two -level of factorial design was employed to analyze the influence of stirring speed, the pH, and temperature in adsorption system containing a finite bath synthetic solution of Remazol Black B dye, operating in pressure system. In the experiments, the volume of the bath and the amount of the adsorbent were kept constant agitation. The ranges of speeds were planned in low medium and higher agitation in water bath. The results showed that the adsorption carried out at elevate temperature has a better efficiency in dyeing, but also the bath pH3.0. The product formed by complexation Remazol Black B and chitin was separated from the solution by decantation, and the amount of the dye do not adsorbed was determined by UV-Vis spectrophometer using a calibration curve in colorant at 597nm. The assays 11 and 13, respectively, indicated absorbance at ? = 597 nm zero, suggesting adsorption efficiency of the dyes takes place in acid médium, and other factors such as time, temperature and speed (rpm) do not directly influenced the process. The operation after dyeing called polishing definitively determine the final result of adsorption, where the use of aluminium sulphate solution at 2%, promoted greater adherence allowed hydrolyzate of the reactive dye in the bath and chitin, suggesting the new proposed physical-chemical treatment to removal dyes pigments from textile effluent, and showed low cost, beyond that generate similar to a non-woven Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Takaki, Galba Maria de Campos (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The amphiphilic L3 (sponge) phase was observed in the late 80's and represents a new class of self-assembly for surfactant-water systems. This work describes the discovery and subsequent characterization of a ternary phase composed of synthetic cationic lipid dioctadecildimetil ammonium bromide (DODAB), pentanol and water in a diluted region. This is the first description of a L3 phase prepared from a lipid with a relatively small polar head and two hydrocarbon chains with 18 carbons each one. The region of the triangle diagram in which there is L3 phase was characterized using optical isotropy and anisotropy to a probe with electron paramagnetic resonance spectroscopy technique. The proposal of an L3 phase was made by comparison with a similar system reported by the group of Montpellier. The description accepted is that in a narrow close ratio of surfactant/cosolvent concentrations, membrane fusion occurs with the formation of a highly interconnected and randomly distributed network of bilayers in space. The assumption of formation of the L3 phase is that the hydroxyl group of pentanol pairs with the lipid heads and this fact is able to change the bilayer curvature. The various DODAB/pentanol preparations remained unchanged and stable for five years only up to the concentration of 3 mM of lipid, the maximum concentration that can be called L3 phase, which is thermodynamically stable. To make the system more attractive for many potential uses it was necessary to increase the weight of the lipid. Concentrations up to 10 millimolar, after a few hours, break down into tiny droplets and small crystals, so-called multiphase. The next step was to completely remove the alcohol by continuous dialysis. The result was the appearance of a phase similar to water, which cannot be obtained otherwise. A sequence of spectroscopic and chromatography measurements showed that the alcohol was entirely eliminated by dialysis as the lipid was retained. There is a notable change when compared with other DODAB/water binary preparations. In the same concentration, all of them have pronounced turbidity. The hypothesis is that the presence of alcohol in the bilayer promotes reorganization, transforming a particulate into a bicontinuum system. Efforts to characterize these systems are justified because they are easy to prepare and have potential uses in the synthesis of inorganic solid new materials with nanostructured pores, and as drug carriers and vehicles for the crystallization of proteins Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Sugarcane bagasse is an agricultural residue highlighted in several countries for its abundance, easy accessibility and low cost. In Brazil, the estimated annual production is approximately 140 million tons of bagasse with only 8,5 million tons are converted into energy. Thus, even using most of the bagasse as fuel in their own distilleries, the overplus is still quite significant and can be used in the manufacture of products with high added value. In order to reuse this waste, this work aimed to compare the processes of soda and organosolv pulping and analyze the influence of anthraquinone in alkaline treatments, since these are the most prominently used in pulp production of high quality. Analysis of variance (ANOVA) and 23 factorial design were performed and results of these analysis showed that the best treatment conditions were obtained with the alkaline pulping with anthraquinone. The influence of anthraquinone was investigated by thermogravimetric analysis (TGA) and quantitative methods were applied to the thernograms in order to determine the apparent activation energy (Ea) on the thermal degradation of sugar cane bagasse and treated with soda in presence and absence anthraquinone. The apparent activation energy (Ea) was calculated using the FLYNN & WALL (ASTM 1641) method considering dynamic conditions, inert atmosphere (N2) and heating rates 1,2,5 and 10°C/min. The treated bagasse by the best condition pulping showed apparent activation energy (Ea) higher. Thus, the best condition for bagasse alkaline pulping was obtained with 9% sodium hydroxide and 0,3% anthraquinone for 3 hours, which exhibited amount of residual lignin 1,166%, cellulose contents 92,54% and apparent activation energy (Ea) ranging with the heating rates between 164 and 188KJ.mol-1 Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Bromelain is a proteolytic enzyme found in vegetable tissues like peel, stem, fruit and leaves of the Bromeliaceae family including pineapple (Ananas comosus). Bromelain is known for its therapeutic effects, being useful in the treatment of several health problems such as digestive disorders, burns and inflammation. This work aimed the purification of the enzyme bromelain from pineapple peel for potential therapeutic application in dermatological bases. It was shown that it is possible to purify bromelain extracted from pineapple peel, a waste in food industry, in a downstream processing, including ammonium sulfate precipitation (40-80%), followed by desalting and freeze-drying with a 75% activity recovery. Ion exchange chromatography on diethylaminoethyl-agarose (DEAE-Sepharose) was able to separate polysaccharides from the enzyme, which was recovered in the elution step, maintaining its enzymatic activity. The enzyme was then incorporated in Lanette cream and lotion, Carbopol gel and Chemyunion cream and lotion at a concentration of 5 mg enzyme per mL of dermatological bases. These bases were subjected to centrifugation test and accelerated stability test during 90 days at 25°C (with and without sunlight), 37°C and 4°C, in order to evaluate bromelain stability in a dermatologic formulation. The formulations were stable as its organoleptic characteristics (appearance, color, smell and sensitivity to touch) only when kept at 4ºC with activity remaining 84.9%, 73.8%, 95.5%, 77.7 % and 72.3% after 90 days of testing in Lanette cream and lotion, Carbopol gel and Chemyunion cream and lotion, respectively. Based on the results, it was possible to purify bromelain from pineapple peel and to incorporate it in dermatological bases maintaining the activity stabler when these bases were kept in refrigerator at 4ºC Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Tambourgi, Elias Basic (advisor), Mazzola, Priscila Gava, 1979- (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: This thesis presents a methodology applied to automate the pipeline inspection process, using image processing techniques to identify the corrosion. As natural gas has some contaminants, besides being corrosive, affect the quality for consumption, thus the condensation of residual water present in the gas corrosion process can initiate a localized, which results in damage to the pipeline structure. Due to the large extension of the ducts, the corrosive affect the quality of the gas and cause major disruptions in operational order. To evaluate the reduction of the wall thickness of the metal, from the corrosive effects were evaluated images which are digitally processed and analyzed by software developed for this purpose which is used to verify the images and at the same time, the identification the problems and guidance of maintenance process. Currently the techniques adopted for this assessment consist to insert a robot, known as pipeline inspection gauge (PIG) with scanning through ultrasound, thermography, optical sensors, Hall Effect sensors and sensors for electrical resistance analysis, plus special field surveys conducted on the soil surface. Thus, the present study was guiding to reduce the costs for maintenance and provide a precise identification of failures. It was implemented a standalone PIG for continuous monitoring of the internal region of the ducts, that fitted with infra-red cameras, what distinguishes this machine from the current for the same purpose. The cameras provide images that are digitally processed and stored in a nonvolatile memory in this machine. The software is used to verify the images and at the same time, identify nonconformities present. This information will be used as a guide in making decisions about the maintenance process that should be used for the solvency of the problems encountered Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: On the petroleum extraction process, the emulsion created between the water and the oil must be broken with the use of demulsifiers, in order to reduce the corrosion problems on pipes and equipment resultant of impurities present in the produced water; furthermore, the excess of emulsified water on the raw oil increases the oil transport costs to the refineries. As a result of the demulsification has been produced water which is often discarded along with the de-emulsifying chemical environment without any treatment; which has been pushing the petroleum industry to replace these by the use biodemulsifiers. Despite its high efficiency in emulsion breaking, the biodemulsifiers have a low yield and high production cost when compared with demulsifiers chemicals. Moreover, bacterias with demulsification capability represent an innovative solution on the demulsification of a W/O emulsion or an O/W emulsion, due to the low toxicity, biodegradability and high efficiency in extreme conditions. On this fact, arose the interest of minimizing costs and therefore the use of agro-industrial waste as alternative substrate for an economically viable production of biodemulsifier. The biodemulsifiers produced by strains of Alcaligenes sp. and Bacillus subtilis using as an alternative carbon font to cassava toxic, which is a liquid reject rich on starch resultant of the cassava pressing process, represents a promising solution to the production of demulsifiers; also reducing the discard of the cassava toxic on the environment and the cost of the . The results showed that the rhamnolipids and surfactins biodemulsifiers are efficient on the breaking of W/O type emulsions, in addition to being less toxic and more biodegradable when compared with the chemical biodemulsifiers, making it an alternate product on the market Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: This study presents the application of three different photocatalytic systems: (1) glass made reactor using an UV-C source (250 W) operating in batch mode through recirculation with the purpose to evaluate the performance of the photocatalysts TiO2, ZnO, CuO or Ga2O3 in suspension on the degradation of a phenol 100 mg L-1 aqueous solution. Results shown that when using TiO2 P25 it was possible to mineralize 80% of phenol after 150 min reaction. When using ZnO it was necessary 300 min reaction to achieve the same performance. CuO and Ga2O3 did not present significant efficiency; (2) compound parabolic collector (CPC) solar reactor operating in batch or continuous mode with the purpose of evaluate a TiO2 P25 surface supported onto a TiO2/SiO2 layer on the degradation of antibiotics (levofloxacyn, ciprofloxacyn, enrofloxacyn, trimetoprym) under common concentrations of environmental water samples. Ciprofloxacyn and enrofloxacyn were fastly degraded by direct photolysis process while levofloxacyn and trimetoprym presented more recalcitrant. It was possible to reach 80% degradation for levofloxacyn and 40% for trimetoprym; (3) titanium assembled reactor using an UV-C source (102 W) operating in batch mode under recirculation with the purpose of evaluate TiO2 P25 aqueous suspension in conjunction with H2O2 on the generation of substances with high commercial value. It was used a factorial planning to evaluate the influence of glycerol, TiO2 and H2O2 initial concentration. It was possible to obtain glycerol degradation of 50% and the main intermediate identified was 1,3-dihydroxyacetone (DHA) with a maximum selectivity of 15% Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Jordão, Elizabete, 1956- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The drying process is the removal through evaporation of a volatile liquid contained in a non-volatile solid. The Spray Dryer is drying equipment which uses the atomization process to increase the contact area of the product to be dried with hot air. Among the advantages can be emphasized to reduce the volume of the product and its weight loss, improving storage and transport. Through a disk rotating at high speed, the fluid is atomized into a chamber generating a mist which, in contact with the hot air, vaporizes instantly. Using this process products are generated in powder form, for example, milk, coffee, egg, soap, fruit juice, coloring agents and antibiotics. The techniques available in the literature for the design of the camera are based on the time of contact of the fluid with air drying rather than the diameter of the spray mist. Depending on the diameter of the chamber is not adequate, the sprayed material and not dried can adhere to the wall and changes the quality of the product. This study aimed to develop an experimental method of low cost to determine maximum diameter of drying chambers to spray dryer with rotary nozzle based on the range of the mist. A wooden plank with adsorbent material placed below the disc allowed quantifying the distance fog. The variables studied to demonstrate the method, were the distance between the board and the disk (200, 300 and 400 mm), the diameters of the discs (30, 40 and 50 mm), rotations (16,800, 21,000 and 28,000 rpm) and flow rates of water supply (2.88.10-3 m³/h 1.96.10-3 m³/h). The results showed high correlation coefficients for the discs 40 and 50 mm, the dimensioning of the maximum diameter of the drying chamber, but to the disk of 30 mm, compared to discs 40 and 50 mm showed a low correlation coefficient independent flow and rotation. It was also observed that, with the disc of 30 mm was obtained the greatest radius spraying; by contrast, a 50 mm disk had the smallest radius of spraying. The experimental unit used to quantify the variables generally neglected in the design and also worthless as not always the point of entry of the material on the disc, disc height, as well as the shape and the side area of the disc Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Aromas arouse great interest among consumers and food industry, especially because heir direct relationship with food taste. In the midst of the most important industrial flavorings stands lactones group, which are present in a wide variety of natural products and biologically active compounds. Due to the prominence of this class of substances, several methods for the production of lactones have been reported. As an alternative to traditional chemical processes, it is proposed in this research the use of microbial and enzyme biotechnology for the production of aromatic compounds natural substrates, such as hydrolyzed vegetable oils. The microbial fermentation is considered a potential pathway for the production of natural flavor, and fungi group is the most widely used for this purpose. Biocatalysis is also a very useful alternative and is able to catalyze a large number of stereo- and regioive reactions, which is not achieved by classical chemical synthesis. The use of isolated enzymes is preferable over the use of microorganisms when there are limitations concerning the permeability of the substrate in the cell membrane or when undesired side reactions occur. Considering these arguments, two methods were investigated in this work for the production of lactones. The first one, biotransformation, was made the use of microorganisms for the production of these compounds. The second method, biocatalysis, was performed by lactonization reaction using crude microbial lipases that was isolated and lyophilized. Substrates used were the vegetable castor and linseed oils previously hydrolyzed by fungal lipases produced by Rhizopus sp. and Geotrichum sp. Lactones production was achieved in both methods. Using biotransformation, all microorganisms tested (Geotrichum sp., Rhizopus sp., Aspergillus sp. (Strains 1068 and 1099) and Fusarium oxysporum) were able to produce different lactone types, especially using the fungus Fusarium oxysporum, which produced a greater variety (&61543;-decalactone, 2-cumaranone, mevalonolactone and pantolactone), achieving the best performance in y-x decalactone production (18.93 &956;L L-1), after 48 h employing castor and linseed oils hydrolyzed by lipase Rhizopus sp. Through the biocatalysis use, excellent results were also obtained, and the lactones production was possible using lipases produced by fungi Rhizopus sp., Aspergillus sp. (Strain 1068) and Fusarium oxysporum. The production of y-undecalactone, y-decalactone and y-dodecalactone was achieved depending on the lipase employed and the reaction time used. Highest yield was obtained in the &61543;-undecalactone production (21.78 &956;L L-1), using castor and linseed oils hydrolyzed by Rhizopus sp. lipase. Lipases produced by Geotrichum sp. and Aspergillus sp. (Strain 1099) was also studied in this work, but were unable to produce lactones Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Macedo, Gabriela Alves, 1971- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The green banana biomass is a component that can be industrially applied to a wide variety of foods because do not interfere in the sensory attributes of other ingredients present and has functional properties, especially the presence of resistant starch. This use can be expanded, including for export, if this product be produced in powder form. This research presents a feasibility study of drying green banana biomass in a non-commercial unit (experimental) of spray dryer with rotary atomizer. The variables selected in the experimental procedure were: the type of atomizer (type A, hole in a rectangular shape with semicircles at the ends and the total area of 162.88 mm2 and type B, hole in a circular shape and a total area of 254.47 mm2); the suspension concentration; the atomizer rotation; the biomass temperature and the biomass flow. The chamber temperature was set at 140ºC with air at 0.013 kg/s. It was defined as response the mass and the relative humidity of the product. These variables had two levels of variation, which corresponded to the completion of 32 trials. Among the variables used in the tests, the suspension concentration was the most significant to responses of mass and humidity, the others showed low effects. The test number 13 presented the best conditions of responses (9.17% and 12.656 g), was obtained with the atomizer type B, 50% concentration, atomizer rotation of 27,000 rpm, biomass flow rate of 40 mL/min and biomass temperature of 30°C. For this sample was realized a microscopic analysis, the granules size do not exceeded 500 ?m, therefore can be used in various food preparations. From the 13 test, the diameter calculation of the drying chamber for a production of 25 kg / h resulted in 5.14 m. In this study it was proved the feasibility of drying the green banana biomass in a spray dryer with rotary atomizer Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The curauá (Ananas erectifolius LB Smith) is a species belonging to the family Bromeliaceae. Occurs in the states of Para, Amazonas, Amapá, Acre, Mato Grosso and Goiás, has two varieties, purple and white, and its fibers are used in automotive and textile industries due to its strength, softness and lightweight and can also be used as animal food. Currently, only the fiber is used in industry, the rest is considered waste. However, this residue contains compounds with important properties to be discovered and studied. An enzyme complex found in this residue is bromelain, which is part of a group of proteolytic enzymes, used in the food industry and as a medicine. Today its use is aiming the pharmaceutical industry, the production of ointments, gels, creams and lotions because they offer a wide range of therapeutic efficacies: antiedemas, anti-inflammatory, antithrombotic and fibrinolytic activities. This study aimed to extract and characterize the bromelain present in the curauá extract before and after purification in aqueous two-phase system PEG / potassium phosphate. A range of aqueous two-phase systems PEG / phosphate, since factors such as pH, temperature and molecular weight of the polymer directly interfere with the purification factor of the sample. The extraction and characterization results showed that the optimum working conditions, where the enzyme activity is maximum, are pH 8.5 and temperature 30 ° C to white and pH 8.5 and 35 ° C for the purple variery before the purification. The molar mass is 24kDa and the best system partition of bromelain was the ATPS PEG 4000 at pH 9. After purification in aqueous two-phase system, another characterization of the enzyme was performed, showing values of optimum pH 8.5 for both curauá varieties, and temperature work of 32 ° C for white and 35 º C for purple. The protein content was measured by Bradford reagent and the enzymatic activity was measured by the Biuret reagent. The enzyme solution of the best purification system contains 7 U of bromelain and about 17 mg/L of total protein measured by Bradford (white curauá) and 6 U of bromelain and about 23 mg/L of total protein measured by Bradford (purple curauá) Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), BasileTambourgi, Elias (advisor), Universidade Estadual de Campinas.

▼ Abstract: Enzymes such as lipase has been widely used in the treatment of effluents with a high content of lipids such as those generated by the food industries. The lipase production by microorganism such as yeast Yarrowia lipolytica in culture media with the use of agro-industrial waste can promote an increase in expression of the enzyme activity, and represents a viable economic alternative to mitigate environmental impacts caused by the accumulation and disposal these wastes into the environment. In this perspective, the whey is a nutritional low-cost alternative for the production of lipases by microorganisms. In this work, the production of lipases in Y. lipolytica on alternate means was investigated with use of whey and the development and characterization of a bioproduct with lipase activity to be used in the treatment of dairy effluent (whey). The analysis of the influence of factors: pH, temperature, substrates (whey and olive oil), stabilizers (glycerol and Triton X-100) and time, were made by successive experimental designs having as variables response to the production and characterization of stability of the enzyme lipase. For the formulation of the bioproduct with lipase activity metabolic liquid was concentrated by an ultrafiltration process and then subjected to the stabilization process. Research on analysis of effluent degradation was carried out through a factorial design to evaluate the effect of formulated bioproduct and a commercial compound nutrient in the period of 48 hours on response variables reduced lipid content, COD and BOD. The results of the production of the lipase enzyme demonstrate that greater production of lipases (172 U/mL) occurred in medium composed of 80% of whey in the absence of olive oil and pH 6.0 for 120 hours of cultivation. The ultrafiltration process used for the concentration of bioproduct enabled an increase in lipase activity to 235 U/mL. On the other hand, significant results on the maximum stability of the lipase activity of 420 U/ mL and 398 U/mL, respectively were determined after storage for 22 and 32 days of bioproduct formulated in the presence of glycerol and 6.0 % of the surfactant Triton X-100 0.1 %. The characterization for stability formulated bioproduct observed the optimum pH to 4.5 and 7.0 keeping 82 % of its activity after 90 minutes incubation temperature and it was found that after 90 minutes incubation at 60 0C the retention of lipase activity of 94%. The preparation lipásico formulated to have elevated rates of hydrolysis for the treatment of dairy effluent whey. The parameters of the COD, BOD and effluent lipids used for evaluating the efficiency of treatment showed that the formulated bioproduct produced a significant reduction in these parameters showing efficiency exceeding 90%. Thus, the results on the stability of formulated bioproduct and treatment the dairy effluent indicate its potential for biotechnological applications Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Salgueiro, Alexandra Amorim (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The State of Minas Gerais is a major producer of cement in Brazil, with twelve enterprises and eighteen rotary kilns, with a total installed capacity of nineteen million tons of clinker a year. Ten of these enterprises have environmental license to carry out the co-processing of waste, consisting in the replacement of raw materials and conventional fuels by a wide variety of wastes, including blends, mixtures prepared in specific units for this purpose, popularly called blendeiras. In the State there are eight of these units, which with together the cement industry, characterize the co-processing sector. Given the sector relevance, and considering that their pollution potential is significant, it was proposed to do an environmental assessment, taking as reference the management of solid waste in the cement industry and in the blendeiras, the control of atmospheric emissions generated in the rotary kilns of cement plants, with approach to influence of these emissions on air quality in northern vector of the Metropolitan Region of Belo Horizonte, the main center for cement production in Brazil, the environmental licensing process and legislation applicable to co-processing in Minas Gerais, Deliberação Normativa COPAM nº 154/2010. The reviews were based on data and information obtained in technical visits to all the State cement plants and blendeiras through a check list prepared to this purpose, and in research carried out in the Integrated Environmental Information System (Sistema Integrado de Informação Ambiental ¿ SIAM). The preliminary research results, subsidized a definition of fifteen environmental parameters, considered the most relevant to evaluate the performance level of the companies that perform coprocessing, for which a series of criteria were defined, which allowed to point such parameters, and to classify the cement plants, taking into account the performance of blendeiras, it¿s suppliers. In this context, seven categories of environmental performance were taken into account ¿ Poor, Very Bad, Bad, Regular, Good, Very Good and Excellent ¿, where two enterprises were included in the category Bad and eight in the category Regular, demonstrating the need for rules and more effective operating procedures, as well as a more embracing and detailed legislation, plus changes in the environmental licensing process, to achieve a more efficient environmental performance in the enterprises Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: During the last years a great variety of microorganisms has been studied for the production of biosurfactants. Biodegradability and low toxicity ensure the inclusion of an advantage when compared to synthetic compounds. However, natural surfactants are still unable to compete economically in the market because of their high cost of production. Thus, the use of renewable sources as a substrate becomes an alternative to minimize production costs and make viable their use in several areas. The pineapple residue is a valid option to avoid the high cost problem. Besides being one of the most produced fruits in the world, pineapple has properties that favor the development of microorganisms and, consequently, the production of biosurfactants. The present work evaluated the feasibility of using the pineapple residue as a substrate for the production of biosurfactants by Bacillus subtilis with studies of residue's characterization, medium optimization and stability analysis, characterization and application of the biosurfactant produced. The results of the characterization of the pineapple residue reported several levels of sucrose, fructose, glucose, protein and lipids, ideal for the production of biosurfactant. The optimization of the environment was performed through statistical analysis with Statistica software (v.10). The optimized medium, containing 15% of inoculum and 95mL of pineapple residue, showed a reduction of 35.42% of surface tension. Stability analyzes showed that the biosurfactant produced is not stable when exposed to 121ºC and presents stability of about 1 hour when applied heat treatment at 100ºC.The results were also not favorable to pH above 4 and salines medium with concentration higher than 5.0%. The characterization results indicated a production of an anionic biosurfactant and its application through the emulsifying capacity was promising for use in food industries Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Tambourgi, Elias Basile, 1957- (advisor), Universidade Estadual de Campinas.
