  1. 26. Concentrated Solar Thermal Plant for Future Fuels Production : Process Modeling and Techno-economic Analysis of Syngasoline, Syndiesel, Ethanol and Methanol Production Using Thermochemical Cycle based on Metal Oxide

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Philipe Gunawan Gan; [2018]
    Nyckelord :;

    Sammanfattning : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). LÄS MER

  3. 27. Fouling Dependency of Air in Dairy Processing

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Lorin; [2018]
    Nyckelord :Fouling; Dairy; UHT; Bubble; Bubble induced fouling; Drying; THE; Dairy Processing; Processing; Bubble Nucleation; Differential Pressure; Oxygen sensors; chemical engineering; kemiteknik; Agriculture and Food Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. LÄS MER

  4. 28. Titanium Surface Properties: A comparison of titanium from two suppliers

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Adam Almström; [2018]
    Nyckelord :Titanium; Titanium corrosion; Electron backscatter diffraction; EBSD; Glow-discharge optical emission spectroscopy; GDOES; materials chemistry; materialkemi; Technology and Engineering;

    Sammanfattning : This master thesis, completed at the company Alfa Laval studied the surface properties of grade 1 titanium from two different suppliers to examine if there were any significant differences between the two suppliers. Previously titanium from the two suppliers had performed differently at times when used in Alfa Lavals heat exchangers. LÄS MER

  5. 29. Process Simulation of Plasma Gasification for Landfill Waste

    Master-uppsats, KTH/Materialvetenskap

    Författare :Tan Boon Hau; [2018]
    Nyckelord :landfill waste; RDF; plasma gasification; syngas;

    Sammanfattning : The growing amount of landfill waste within the EU could pose a problem in the future should there not be any effective treatment methods. This study aims to investigate the performance of landfill waste in a plasma gasification process by simulating the process in ASPEN Plus. LÄS MER

  7. 30. Inverse correlation between freeze-thaw survival and storage stability of freeze-dried Lactobacillus reuteri DSM 17938 and a microcalorimetric search for GASP

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Radoslaw Sawicki; [2017]
    Nyckelord :freeze-drying; lyophilization; Lactobacillus reuteri; probiotic; pH; temperature; freeze-thaw; storage stability; survival; morphology; microscopy; long-term stationary phase; GASP; isothermal microcalorimetry;

    Sammanfattning : Lactobacillus reuteri DSM 17938 is a probiotic bacterium manufactured by the company BioGaia AB and was in focus of this study. If a probiotic product is to confer its benefi-cial health effect to a consumer, it must retain high viability levels during long-term storage. LÄS MER
