▼ Energy is a hot topic in today's society. Both businesses and individuals are trying to reduce their spending costs by saving kWh. There are many various saving measures to reduce energy consumption. Reducing energy consumption leads to a reduced carbon footprint as less fuel is burned in facilities that generate emissions. This report will focus on heat pumps, solar technologies and interventions in the building envelope for a multi-dwelling house. How much energy can be saved from a measure? What impact does it have on the climate? Is it economically viable to invest in the measure? These issues are of importance both for the investor and future generations. In the report, these questions are answered and applied in a multi-dwelling house in Karlstad built in the 1960's with an energy consumption of 129 kWh/m2 and year. The study is a collaboration with HSB. The building was recreated in a simulation program, VIP-Energy, for a basic case to start from. Then the measure were simulated both individually and in combination to see how effective they are in the building. These measures may lead to an increased electricity consumption, which was taken into account in the calculations of the climate impact if it led to an increased or decreased amount of CO₂ emissions. All these measures are designed to reduce energy consumption, leading to a decrease in energy cost. The results showed that these measures lead to a saving of energy consumption in all cases. The resulting reduction in energy consumption varies between 5-50% on the various measures individually, but the savings do not differ as much. The reason for this is the technical lifetime of the measures, which means that the total savings do not reflect the reduction in energy savings. Reduced CO₂-emissions is much more difficult when the building is connected to a district heating plant that also produces electricity, known as a combined heat and power plant, which makes the reduced heat generation leads to reduced power generation. This means that the electricity has to be generated from another source, for Sweden this means imports of electricity from a coal condensing power plant. Electricity from the power plant is in this case CO₂-compensated, which means that the fuel comes from a renewable source. In order to have reduced CO₂-emissions, it requires that you have your own production of electricity from CO₂-compensated or renewable sources.

Energianvändningen i världen ökar på grund av ökad befolkningstillväxt och industrialisering. En av de viktigaste nycklarna för att bromsa den rådande utvecklingen är att genomföra energieffektivisering, främst inom industrisektorn där det ofta finns outnyttjad energi som skulle kunna återanvändas med hjälp av ny teknik.Valmet AB är ett företag som nyligen köpt ett gjuteri av ett konkursdrabbat företag. Köpet var tvunget då deras verksamhet är beroende av unika delar som gjuteriet producerar. Valmet AB, som profilerar sig som ett företag med energi- och miljöfrågor i fokus, vill undersöka om den nya verksamheten går att energieffektivisera.Smältning av metall är energikrävande och därför har gjuteriet ett stort energibehov smtidigt har de flera processer som genererar spillvärme. Första delen av arbetet syftar till att visa hur mycket och vilken sorts energi som gjuteriet använder samt hur elbehovet fördelas mellan olika processer. I andra delen kartläggs gjuteriets spillvärmeflöden och i sista delen behandlas olika fall av värmeåtervinning utav spillvärme.Energikartläggningen visade att gjuteriet använder flera olika energislag men att el är det dominerande. Av det totala energibehovet är 81 % el, vilket är ungefär samma resultat som har erhållits i tidigare kartläggningar som gjorts hos andra gjuterier i Sverige. Smältugnarna har det största elbehovet vilket också har pekats ut som den mest elkrävande processen i tidigare arbeten.Spillvärmekartläggningen påvisar tre intressanta spillvärmeflöden. Det ena är ett spillvattenflöde från ugnarnas kylsystem och de andra två är de luftflöden som värms upp då gods och sand svalnar. Det flöde som valdes att gå vidare med var kylvattenflödena från smältugnarna. Temperaturen på returvattnet från ugnarna varierar mellan 25 och 0°C. Den låga temperaturen gör att det betraktas som lågvärdig spillvärme. Med denna spillvärme kan vatten som har en lägre temperatur förvärma exempelvis duschvatten och radiatorvatten. Förvärmning av inkommande ventilationsluft är också ett alternativ. Det sistnämnda alternativet väljs ut och studeras utifrån energisparande ekonomiskt och miljömässigt perspektiv.Genom att värma ingående luft med hjälp av ett spillvärmebatteri som drivs av vattnet från de två kylsystemen ifrån ugnarna kan temperaturen på ingående luft i snitt höjas 5-25°C. Detta gör att det befintliga fjärrvärmebatteriet inte behöver värma luften lika mycket. Valmet AB sparar 648 000 SEK varje år vid installation av ett spillvärmebatteri samtidigt som fjärrvärmeleverantörerna kommer att minska sin bränsleenergianvändning med 9500 kWh per dygn.

Energy consumption is increasing worldwide due to population growth and industrialization. To slow down the current trend it is important to implement energy efficiency.Valmet AB is a company that recently bought a foundry of a bankrupt company. It was necessary because the company relies on a unique part that the foundry produces. Valmet AB, which is a company with energy and environmental issues in focus, wants to investigate whether…

Siemens BT in Umeå has conducted an energy project (EPC - Energy Performance Contracting) of a number of items at the municipality of Lycksele. An EPC project was carried out by Siemens Building Technology (BT) and consists of three different phases; project development, project execution and project follow up. Now all three phases has been completed and it has been seen in the monthly energy follow up that despite the optimization of the properties, there are properties which do not receive the savings they anticipated during project development report and the energy audit. This is where the master degree project continues, with analyzing, evaluating and proposals for actions for these three objects: Forsdalaskolan, Furuviksskolan and Storgården.A feasibility study was carried out for each object and their separate project development reports, energy audits and different documented meetings of various kinds. After the feasibility study arose different issues that resulted in an inspection that were checked for all of the objects. Each object were visited one by one, and during the visits all of the information was noted and documented. If necessary measurements was carried out in the objects various areas. Finally, one object was elected, object one, Forsdalaskolan, for a brief simulation in the simulation tool IDA ICE (Appendix D) with respect to the buildings outer case.The result of the analysis and evaluation of the EPC project with respect to these three objects was that there were inadequately in both documentation and communication between the parties which resulted in some baseline corrections needed to be implemented and adjusted. Another factor that showed signs of affecting the objects performance was the human behavior. It is recommended that communication and understanding of human behavior is improved with the help of handing out brochures and when it comes to documentation the recommendation is new ways of working with notes in the energy audits and other documents to clarify the work that has been done, calculations made and the assumptions taken along the whole project.EPC projects were found to have both advantages and disadvantages. The advantage of making use of an EPC project was the possibility to package the actions for the large number of objects. By doing that more actions could fit into the estimated profit which enabled more actions to be included in the EPC project that did not equal as much savings in the short run. The disadvantage of EPC projects was a Catch-22 that occurred in phase 1. In phase 1, the foundation of the whole project is compiled but it’s also the same phase that aren’t being paid for if the entrepreneur doesn’t land the other two phases. This makes the entire phase 1 very risky and important for the project's outcomes.

▼ Opinnäytetyöni päätavoite oli esitellä merenkulun ammattilaisille suomalaisen pienyrityksen Eniram Oy:n kehittämä uutuustuote, laivan trimmausjärjestelmä (OTA -järjestelmä = Dynamic Trimming Assistant), jonka avulla on mahdollista päästä jopa 5 % säästöihin laivan polttoaineen kulutuksessa. OTA -järjestelmän toiminnan ja käytön esittely tapahtuu tässä opinnäytetyössäni kuvien ja taulukeiden sekä niihin liittyvien tekstien avulla. Toinen tavoite oli saada esille OTA -järjestelmään ja sen laitteisiin mahdollisesti liittyviä puutteita, ongelmia ja tietysti tärkeimpänä asiana saada nostettua esille käyttäjiltä mahdollisia parannus- ja kehitysehdotuksia Eniram Oy:lle tuotteen jatkokehittelyä ajatellen. Noiden kahden päätavoitteen lisäksi esittelen tässä opinnäytetyössäni myös hiukan Eniram Oy:tä ja sen asiakasmäärän, henkilöstömäärän ja liikevaihdon kehitystä viimeisen viiden vuoden aikana sekä sitä, kuinka paljon järjestelmän avulla on mahdollista vähentää laivojen polttoainekustannuksia sekä kasvihuonekaasupäästöjä Ensimmäinen opinnäytetyöni tavoite toteutui oman työnantajani NCL:n risteilijöillä pääosin jo siinä vaiheessa, kun kansipäällystö sai risteilijöiden komentosillalle kaksi kertaa pienen ajan sisällä sähköpostitse nuo "ENIRAM'S OTA -System QUESTIONNAIRE" kyselylomakkeeni. Tuolloin kaikkien risteilijöidemme komentosilloilla syntyi keskustelua päällystön keskuudessa OTA -järjestelmästä ja sen käyttöön liittyvistä asioista sekä sen avulla saavuteltavasta polttoaineen kulutuksen pienentymisestä. Uskoakseni nuo kaksi pienin väliajoin lähettämääni kyselyä myös herätti syvällisemmän kiinnostuksen tuota uutta järjestelmää kohtaan jokaisella risteilijällämme. Noiden kahden kyselyn lisäksi olen itse käyttänyt tuota järjestelmää NCL:n neljällä eri risteilijällä sekä keskustellut järjestelmään ja sen käyttöön liittyvistä asioista monien päällystön edustajien kanssa. 33 Toisena tavoitteena oli saada käyttäjiltä tuota uutta OTA -järjestelmää koskevia parannus- ja kehitysehdotuksia Eniram Oy:lle. Kuudeltatoista OTA -järjestelmän käyttäjäitä saatujen kyselyvastausten sekä neljällä NCL:n risteilyaluksella päällystön kanssa käymieni keskustelujen perusteella voin todeta, että käyttäjät ovat olleet pääsääntöisesti tyytyväisiä tuohon uuteen järjestelmään. Käyttäjiltä tuli monenlaisia ideoita ja kommentteja, mutta yksi noista kehitysideoista oli lähes kaikkien vastaajien lomakkeista luettavissa eli lisänäyttöjen tarve komentosillalla. OTA -järjestelmät on pääsääntöisesti asennettu kaikkiin NCL:n risteilylaivoihin ns. jälkiasennuksena ja jokaiseen järjestelmätoimitukseen on kuulunut vain yksi kosketusnäyttö, poikkeuksena Norwegian Gem. Tuo yksi kosketusnäyttö on jälkiasennuksesta johtuen jouduttu sijoittamaan kunkin risteilyaluksen komentosillalla parhaaseen mahdolliseen vapaaseen paikkaan, joten tuosta syystä se ei ole yhdelläkään risteilijällä optimaalisessa paikassa. Edellä mainituista syistä johtuen useimmat kyselyyn vastanneista toivovat komentosillalle 1 - 2 kpl lisää kosketusnäyttöjä.… Advisors/Committee Members: Yrkeshögskolan Novia.

▼ Detta examensarbete utfördes på uppdrag av Akademiska Hus AB i Umeå under våren 2017. I det här arbetet utfördes en energiinventering av elanvändningen i Universumhuset på Campus i Umeå. Akademiska Hus planerar en större ombyggnation av Universumhuset. Mindre renoveringar och ombyggnationer har genomförts under åren, men vissa system och konstruktioner är från byggåret 1970. Idag finns ett flertal olika hyresgäster och verksamheter inom byggnaden. I det här arbetet gjordes en inventering och fördelning av byggnadens årliga elanvändning. Fördelningen av elanvändningen beräknades dels efter objektskategorier men även för användningen av fastighets- och hyresgästel. Syftet med detta var att skapa ett underlag för energibesparande och energieffektiviserande åtgärder inför planerad ombyggnad. Utöver detta gjordes även analyser av byggnadens effektnivåer och utredningar för möjlighet till behovsstyrning av anläggningen. Utifrån inventering konstateras att byggnadens totala elanvändning är ca 1200 MWh/år, var av fastighetsel står för 53 % och hyresgästel för 46 %. Resultat för beräknad fördelning av byggnadens totala elanvändning visar att storköksutrustning står för den enskilt högsta elanvändningen på 23 % följd av belysning 19 %, värmepump 16 % och fläktar 13 %. Den årliga energianvändningen beror på utrustningens effekt och driftstid och fick i många fall antas. Elanvändnigen beror på flera olika anledningar och varierar under året. Stora delar av utrustningen är även behovsstyrd vilket ger stora variationer och ger en viss osäkerhet i den beräknade fördelningen. För en effektivare elanvändning föreslås generellt en utökad behovsstyrning för styrning av byggnadens system. Universumhuset har idag en stor del äldre utrustning vilket föreslås bytas ut mot modern utrustning med ny teknik. Även förändring av beteendet för användningen av utrustningen rekommenderas, vilket skulle kunna resultera i en betydlig energibesparing.

▼ With increasing energy prices and increased focus on the environment we saw the need for companies to get control over their energy use and their emission of carbon dioxid. An analysis tool that integrates both these areas is, with our knowledge, not available on the market today. Therefore, our project became to develop such a tool. By doing this degree project we would like to clarify that energy consumption and environmental impact are integrated. The less energy consumed by today’s society the smaller the environmental impact will be. Seen from an economical point of view the benefits from a reduced energy use are significant due to the fact that costs will diminish, for companies as well as people in general. Even the choice of energy source has an effect on the environmental impact. The objective has been to provide a tool which companies can use to conduct their own analyse on their energy consumption and carbon dioxide emission, and also point out where in their business they can find such “hot-spots”. In the provided Microsoft Excel based analyze tool there is a total of eight different sections out of which six concerns different parts of a company. Five of these six sections will be filled out by the user and the sixth gives a compilation of the company’s energy consumption and carbon dioxide emission. These sections are: Start, Introduction, Electricity, Heating, Cargo transports, Personal transports, Compilation and References. The sections are organized to make it more user friendly and to show the most important parts of a company, concerning both energy consumptions and carbon dioxide emission. When we considered the tool to be finished, we had it sent out to a number of companies that tested it on their businesses and returned their opinions and suggestions on various changes. In the beginning of the project our objective was that at the end we would have a complete tool ready for companies to use on their activities. This however, turned out to be too much of a challenge, which we realised after just a few weeks. The produced tool instead became a prototype for further development. All in all, the work has given us a valuable insight in the magnitude of work and time required for developing this kind of analysis tool.

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem. Sketches, LEGO and engineering methodologies have contributed to the good result.The recommended solution generated by this project is to place two regular sized turbines by 2.9meters. The first turbine is placed in its optimal position at the Driver side of the turbine, themomentum provided by the water is leaded by a shaft towards the engine side of the machine. Thesecond turbine is placed directly under the first shaft. This allows the second turbine take care of therest of the water and energy.

SammanfattningDetta examensarbete är en del av innovation - och designingenjörsprogrammet vid Fakulteten förhälsa, natur- och teknikvetenskap vid Karlstads universitet. Omfattningen av detta arbete är 22,5högskolepoäng och har utförts självständigt av Hannes Jernberg under våren 2013. Uppdragsgivarentill detta arbete var Arvid Johansson vid Metso Paper Karlstad AB. Metso Paper Karlstad AB varvärldsledande utvecklare och tillverkare av tissue pappersmaskiner.I dagsläget har företaget utvecklat och patenterat ett energisparsystem med en Cross-flow turbinbegränsad till pappersmaskiner med en pappersbanbredd på ungefär 2,9meter. Företaget vill tatillvara på alla möjligheter som patentet ger, samt utveckla en turbinlösning till pappersmaskinermed en pappersbana som är bredare än 5,5 meter. Vilket i sin tur ger möjligheten att tillverka pappertill lägre energiförbrukning, vilket är en viktig del av en process som är mycket energikrävande.Problem uppstår med den ökande turbinlängden, förlängningen resulterar i att nedböjningen blir förstor samt att vridningen på grund av det ökande momentet vid kraftuttaget får turbinbladen attbrista.Genom att tillämpa designprocessen har detta arbete…

▼ WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ”thermal climate summer” and the ”daylight”. The simulation program VIP-Energy was used to investigate how the different solar shadings: blind, marquis and fixed screen affected the cooling need of the second floor of the preschool. Possible actions for increasing the inlet of daylight are discussed. Two measures were identified: increasing the glass area and changing to windows with higher transmission of light. If the information about the use of energy which has emerged in this thesis is considered it will not be sufficient to only improve the ”thermal climate summer” and the ”daylight” in order to improve the level of certification.

▼ There is ongoing research on the spray fundamentals in high pressure fuel injection. A basic understanding of the physical aspects of spray formation enables improvements of the injector designs and enhances combustion optimization. High-pressure sprays are complex flows and involve phenomena and physical mechanisms that often require further research before becoming integrated part of the existing spray models. One such phenomenon is the existence of low-level rotational movement (swirl) in the near-field of common production injectors. This aim of this work is to investigate swirl and quantify the degree of radial motion along the centerline of the spray. A new measurement approach is employed in order to overcome the difficulty resolving liquid structures in this region due to its high optical density. Here, dodecane is doped with a long-lived phosphorescent tracer, consisting of Eu-TTA-TOPO. A thin laser-light sheet excites the centerline of the quasi-steady spray, leaving a distinct mark on it. A high-speed CCD camera coupled with an intensifier is used to capture a pair of images shortly after the initial fluorescence has faded away. The light intensity of the signal is tracked between the two images allowing calculation of the radial shift of the signal. Two single-hole injectors with different orifice hole geometries were tested; one with conical orifice and one with cylindrical. Two different sets of data are analyzed. The first consists of single pairs of images with varying timesteps between the two images for 600, 1000 and 1600 bar. The second is a statistical analysis of 50 images for a constant timestep of 6μs and for 600, 800, 1000 and 1200bar. The results show that the light-shift increases in a linear fashion by increasing the timestep, the cylindrical hole injector results in higher calculated light-shift than the conical injector and there is not a clear relation between the shift of light and the injection pressure. This work also discusses the sensitivity of the results to parameters of the analysis.

▼ The aim of this thesis has been to investigate the impact of wave energy in the electric power system of southern Sweden. How does wave energy correlate with wind power generation in the area, and can a less variable generation pattern from wave energy allow it to have a higher investment cost than wind energy? The study has been performed using meteorological data for the region from the European Centre for Medium-Rage Weather Forecasts, ECMWF, and a computer model of the electricity system. The weather data was analysed to gain a better understanding of wave power generation in general and in the area, and also to investigate the correlation between wave and wind energy. The effects of wave power on the electricity system have been analysed by using a cost-minimizing model of the electricity generation system, developed outside of this thesis. The main outcome of this thesis is that there are benefits of combining wind power generation in southern Sweden with wave power generation on the Swedish west coast, compared to only increasing wind power generation equally much. The benefits are in terms of reduced system operational costs, and the savings are in the range of 1% of the system operational cost, explained by a reduction in peak cost, lower cycling cost and less curtailment of wave and wind power generation. Since the two sources are highly correlated in the area, wave power in general is available at the same time as wind power is available, and thus the gain of combining the two sources in this specific area is reduced. In an area with lower correlation between waves and winds, the gains of combining the two sources could be higher. When it comes to the cost of the wave power compared to wind power, the outcome is that the determining factor for how the costs are related is the capacity factors. The higher capacity factor for one of the investigated technologies within this thesis was found to enable wave power to cost about 50% more than wind power per generator capacity. The system benefits of having a mix of wave and wind compared to wind only further increases this cost difference per generator capacity by one or two percentage. Wave power also has other benefits compared to wind power, such as higher public acceptance and higher energy density in the resource. The wave power industry might be in the starting blocks of a great exploitation in the coming years. Experience from the wind and solar industry tells that once things start happening, the growth in installations may be explosive. Future development on prices, investment trends, public acceptance etc., will govern the development in the wave power industry.

▼ In EfW (Energy from Waste) boilers, flue gases can create corrosion of the superheaters and economisers, caused by deposits of the melted ashes. Due to this, the flue gases are cooled with water wall panels and water tube walls in a cooling pass before reaching the heat transfer surfaces, thus limiting the power output. One way to increase the efficiency of the boiler is to introduce superheater screens in the cooling zone instead of using water wall panels to cool the flue gases. This new superheater would be covered in a ceramic material to protect its tubes from the above-cited fouling. The purpose of the present work was to create a 1D model that describes the heat transfer from the flue gases to the coolant (steam and water) in the flue gas cooling pass of a power boiler. The 1D model, which is validated against CFD simulations using the Discrete Ordinates (DO) radiation model, will be used in the retrofit of EfW boilers. Furthermore, CFD simulations are used to study the pressure loss and mass flow distribution in the cooling pass under different situations and to provide design correlations. Also, the influence of different parameters on the computational cost of the CFD simulations is examined. The 1D model agreed fairly well with the CFD simulation, especially in the lower part of the cooling pass. The flue gas outlet temperature was 4.5% lower in the 1D model than in the CFD simulation. In the 1D model, the geometry could be approached as rectangular canals, neglecting the inclination of the ceiling, and modelling the inlet and the outlet of the cooling pass as water tube walls. Regarding the flow field, the mass flow distribution in the cooling pass was found to be independent of factors such as the mass flow rate and the number of screens. It is sufficient to calculate the relative depths of the canals to get the mass flow distribution. The pressure loss can be found as a function of the average flue gas velocity in the cooling pass. The CFD mesh required approximately half a million cells, and the computational cost was decreased by using a symmetry plane in the middle of the cooling pass, costing just over an hour.

▼ One of the greatest challenges of our time in an environmental point of view is greenhouse gas emissions and specially carbon dioxide emissions. Higher levels of greenhouse gas in the atmosphere leads to a raise of the average temperature on earth, which results in disasters such as drought, storms and flooding. Carbon capture and storage is therefore a necessary technology to develop, especially for fossil fuels but also for biomass. With carbon capture and storage from fossil fuels the emissions can at the very best be reduced to zero but it is not possible to remove carbon dioxide from the atmosphere, this is made possible by using biomass combined with storage. In order to achieve so called negative emission levels, which results in lower greenhouse gas levels in the atmosphere, it is necessary to implement new technologies. There are currently a few proposed technologies for carbon capture and storage and this report aims to study a new process technique, wet oxidation with oxygen, which is intended to be implemented in the pulp- and paper industry to make carbon capture and storage possible for the carbon dioxide produced by oxidation of black liquor. The process is intended to replace the recovery boiler and the evaporator and since two major process units are replaced this can enable economic savings and significant emission reductions. A modelling of a reactor was included in the project and it shows that by replacing air with oxygen a higher temperature can be achieved in the reactor. Furthermore, the degree of conversion is higher when using oxygen, partly because of the higher temperature but also because of a higher concentration of oxygen in the reactor. The process optimization shows that the process is self-sufficient and that excess process steam can be exported. The results show that about 400 million SEK can be saved using a process with a capacity of 35.275 kg/s compared with investing in a new recovery boiler with carbon capture and storage, and that the designed process can capture about 0.27 million tons’ carbon dioxide/year. The degree of separation for the process with respect to carbon dioxide was 88.6 mole % and the conversion with respect to the organic fraction in the black liquor was over 98 %.

▼ The powder coating industries in Sweden use about 525 GWh of energy every year. The need to reduce the energy use is increasing due to increasing energy prices but also due to demands from customers. Most plants uses LPG and electricity, which has an energy price that is expected to increase by 50-60 % until 2020 compared with the prices in 2010. This type of industry has had focus on environmental issues concerning hazardous chemicals and powder types. However, focus has not been on energy efficiency measures. In this project the powder coating company Quality Powder Coating AB was investigated. At the same time Sofie Osbeck from Linköping University conducted a parallel project at LaRay AB. The objective of the projects was to perform energy audits and calculate possible energy efficiency measures to see the energy efficiency potential within this type of industry. The project was separated into four main parts. These parts were fact and data collection, energy audit, calculations of energy efficiency opportunities and benchmarking with the project at LaRay AB. The energy audit showed that QPC AB uses approximately two GWh of energy each year distributed on LPG, electricity and district heating. The biggest consumers of energy within the plant are the cure oven, drying oven and pre-treatment unit. The largest consumer of electricity is the powder box due to its high ventilation. The heat exchange possibilities were investigated by the use of pinch analysis and three possible networks for heat exchange were compiled. These networks are either based on heat exchange for the ovens or with an additional cooling zone. In this project it was showed that the energy usage for QPC AB can be reduced with 420 MWh of energy per year which equals 21% of their total energy consumption. This energy reduction will also lead to cost savings of 24% compared with 2010 or 330 000 SEK per year and savings of carbon dioxide emissions of 157 tonne or 25%. The results for the project at LaRay AB were that the energy use can be decreased by 30%. Since powder coating industries is quite homogeneous the conclusion of these two projects is that the energy use within powder coating industries can be reduced by at least 20%, which responds to 105 GWh per year. Benchmarking between the two projects showed that heat exchange should be conducted within the same unit in the process.
