▼ A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include higher-harmonic wave components. The effects of mass transport in a closed wave flume is studied with particular attention given to the return flow, changes in wave celerity (frequency), and to the surface drift velocity. The laboratory waves generated by a plane wave board are shown to be composed of two components; viz., a Stokes second-order wave and a second-harmonic free wave which travels at a different speed. The amplitude of the second-harmonic free wave is relatively large in shallow water and decreases to less than 10% of the amplitude of the primary wave in deep water. Wavemakers with relatively deeper draft (i.e., hinged near the bottom) generate the free waves of smaller amplitude in shallow and intermediate water depths than the wavemakers with shallow draft. However, the opposite is predicted by theory in deep water. The fifth-order theory for the Lagrangian motion of water particles gives good predictions for the mass transport velocity for Stokes waves. The existence of the secondary free wave in laboratory channels results in an increase in the mass transport velocity over the whole depth. For both a flap-type wavemaker hinged on the channel bottom and a piston-type wavemaker, the increase at the free-surface is within 13% of the values for the Stokes wave only, for the wave steepness parameter 0.02 < H/L₀ < 0.16. For these two types of wavemakers, the decrease in wave celerity (frequency) due to the uniform return flow is within 6% of its value in an open flume for the wave steepness parameter 0.02 < H/L₀ < 0.12. The decrease in surface drift velocity due to the return flow is as large as 58% (20%) of the value in an open flume for waves with the steepness parameter H/L₀ =0.02 (0.14) at the relative water depth h/L₀ = 0.05 (0.30).

Thesis (MScEng (Process Engineering)) – University of Stellenbosch, 2011.

ENGLISH ABSTRACT: Structured packing is often the preferred choice for column internals because of its low pressure drop and high efficiencies compared to that of trays and random packing. However, the mass transfer phenomena in these gas-liquid contacting devices is still not well understood, even though it is widely used in industry. A contributing factor to this is the lack of understanding and availability of experimental data in the open literature. These shortcomings complicate the design of a distillation column and make practical experience essential. There is thus a need for more experimental data, especially for packings where only limited information is available. The focus of this study was to establish a testing facility that can be used to measure the efficiency of structured packing under total reflux, and not to measure vast quantities of experimental data; the latter will be done in future. The facilities available at Stellenbosch University limited the internal diameter of the column to 0.2 m, which is sufficient to test higher surface area structured packings (≥350 m2/m3). The column is used with a thermosyphon reboiler that uses steam as the heating source and is equipped with a total condenser. Two sections are used for the packed bed that allow for a total packed height of 3.78 m (2x1.89 m). The column is set up to operate under total reflux and was designed to operate at pressures ranging from 0.3 to 1 bar abs, vapour flow rates of 0.73 – 3.65 (m/s) (kg/m3)0.5 and liquid flow rates of 5 – 25 m3/(m2.h). It was found that the 2-butanol/iso-butanol and the p-xylene/o-xylene systems are suitable test mixtures for this pilot plant setup. The VLE data from Kutsarov et al. (1993) and Zong et al. (1983) for p-xylene/o-xylene and 2-butanol/iso-butanol are thermodynamic consistent and was validated by VLE experiments done in this study. It was found that the experimentally obtained efficiency (HETP) and pressure drop data for Mellapak 350Y compared well with published results of Spiegel and Meier (1987). With regard to the predictive models, it was found that i) the SRP model predicted the HETP of Mellapak 350Y structured packing accurately in the pre-loading region and slightly over predicted the HETP in the loading region, whereas ii) the Delft model over predicted HETP and iii) the Billet and Schultes model under-predicted HETP under the entire tested range (i.e. over-predict efficiency). With regard to the pressure drop data i) the Billet model iv accurately predicted the pressure drop over the entire tested range, whereas ii) the SRP model accurately predicted the pressure drop in the pre-loading region and slightly over predicted the pressure drop in the loading region and iii) the Delft model over predicted the pressure drop over the entire range and followed an almost parallel trend to the results from the SRP model. It was also found that information in the field of mass transfer in a…

▼ RESUMEN: En este trabajo se ha realizado el diseño del proceso de purificación de estireno mediante adsorción en alúmina. Esta purificación consiste básicamente en la separación de agua y el inhibidor de la polimerización, 4-terc-butil catecol (TBC), presentes en el estireno como etapa previa en la obtención del caucho sintético, ya que la presencia de estos compuestos dificulta y encarece dicha operación. Para determinar las condiciones experimentales de trabajo, se ha tomado como referencia un proceso operativo actualmente a escala industrial en la planta de fabricación de caucho sintético que la empresa Dynasol Elastómeros posee en Gajano (Cantabria). Así mismo, se ha empleado el estireno que esta empresa utiliza como materia prima que posee alrededor de 150 mg/kg de agua y 15 mg/kg de TBC. En primer lugar, se ha procedido a la determinación de los equilibrios de adsorción agua-alúmina y TBC-alúmina. A continuación, se ha efectuado una serie de experimentos dinámicos a escala de laboratorio en los que se han obtenido la evolución de la concentración de cada uno de los adsorbatos en el estireno a la salida de la columna de adsorción en función del tiempo. Posteriormente, se ha llevado a cabo el desarrollo del modelo matemático para lo que se han analizado las distintas etapas en el proceso de transferencia de materia, así como sus consecuentes resistencias, y se han obtenido los parámetros correspondientes. A continuación, se ha realizado un análisis del cambio de escala, para lo que se ha procedido a la construcción de una planta piloto en la propia factoría que produce el caucho sintético, en la que se han realizado diversos experimentos que han sido contrastados con las simulaciones que predecía el modelo matemático. La comparación ha permitido validar el modelo y los parámetros cinéticos. Finalmente, utilizando el modelo y los parámetros obtenidos en las etapas anteriores se ha simulado el proceso de purificación de estireno operativo a escala industrial.

▼ The industrial application of gas-liquid contactors has made effective design and optimisation of these processes a very important topic. In order to sustain a competitive advantage, rate limiting steps must be clearly understood. Hydrodynamics, heat transfer and mass transfer are complicated features of gas-liquid contactors and require a fundamental understanding. The mechanism of mass transfer in the presence of a small concentration of solid micro particles has been the subject of debate. The adsorption of gas by solid particles ("shuttle mechanism") is the traditional explanation. Recent experimental evidence suggests that the introduction of micro particles removes trace surface active impurities from the system and allows the true mass transfer coefficient to be measured. The objective of this study was to confirm the surfactant removal theory. Mass transfer is a field characterised by imprecise empirical relationships and difficult to obtain experimental parameters. This puts into context the significant challenge posed in preparing the careful set of measurements and analyses presented in this study to lend support to the surfactant removal mechanism. The study began with a review of mass transfer models. These models are based on concepts such as surface renewal and idealised turbulence. It is, however, difficult to choose between the models as they predict similar values despite being based on different mechanisms. The overall mass transfer coefficient is composed of the gas-phase coefficient (kGa) and liquid-phase coefficient (kLa). As the values of the coefficients are comparable and the solubility of oxygen or hydrogen is very Iow, the overall mass transfer coefficient is approximately equal to the liquid side coefficient. The relationship of kL with the diffusion coefficient (D) is one of the limited ways of choosing between the models. Mass transfer models predict k j • u:. D" . n is predicted to be % for a rigid surface (contaminated interface region) and Y2 for a mobile surface (clean interface region). If the surfactant removal mechanism applies, the introduction of solid particles will be accompanied by a reduction of n from % to 1/2. The effect of particles on n can be calculated from precise measurement of kL of gases with significantly different diffusion coefficients. A review of experimental methods was made to find precise methods to characterise mass transfer in the presence of solid micro particles. The chemical sulphite, gas-interchange and pressure step methods were identified as appropriate methods. These were implemented in a stirred cell (0.5 !) and an agitated tank (6 I). The chemical sulphite measurements were used to confirm that the enhancement of kLa is due to an enhancement of kL and not the specific interfacial area (a). Flat surface experiments were made using water and 0.8 M sodium sulphate batches. The reduction of n from % to Y2 was confirmed in both apparatuses after the addition of solid particles. The data were very well correlated…

▼ Gas shales contain an abundance of natural gas. Low-permeability ("tight") shale is commonly found domestically in the Appalachian Basin but it has yet to be fully explored. A major limitation to the efficient extraction of this "tight gas" is the current lack of knowledge of the physics and mass transfer properties involved in production from such low-permeability porous materials. Without an improved fundamental understanding and appropriate modeling and simulation, forecasting of natural gas production from these formations will be inaccurate and unreliable, and operators must continue relying on "trial and error" in their development strategies. With the demand for natural gas continuing to surge, an urgent need, therefore, exists today to improve the efficient drilling and completion of new wells as well as for re-completion of existing wells in order to meet this increased demand. As a result, we not only need to drill and complete more wells, we also need to improve production efficiency on a per well basis. ❧ In this study we have characterized the properties of gas shales and the fundamental mass transfer mechanisms associated with the gas production process; we have developed, in addition, a new method to reduce water-blockage related formation damage. A set of techniques have been employed systematically during our shale characterization work, which provide us with ways to better understand the unique physical and chemical properties of these shale materials. These formations, for example, are characterized by a very low and anisotropic permeability, with the horizontal permeability being much higher than the permeability in the vertical direction. Our experiments using BET with these shale samples have revealed that they possess multiple levels of porosity, ranging from microporous and mesoporous regions (characterizing the sample's matrix) to macropore/microfracture domains. ❧ We have also designed and carried out high-pressure gas depletion experiments in order to study the gas production behavior of these shale samples and the various mass transfer mechanisms that prevail. Furthermore, we have utilized the experimental knowledge generated to form the basis of a simple continuum-type model to study gas depletion from these materials. Our high-pressure system was designed in such a way as to mimic the actual formation's pressure conditions, so that we can independently control the pressure parameters to study the resulting production behavior of the shale core sample. The analysis of the experimental data indicates that the gas that depletes during the early stage is free-gas from the macropore/microfracture domains (as well as the macrofractures that may also be present in these small size, lab-scale samples). The gas depleted at longer times is via a desorption-diffusion-viscous flow process from the shale matrix. We use numerical simulations to analyze the model in order to understand and interpret the experimental behavior we observe during our lab-scale, high-pressure depletion experiments.
