  1. 16. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Laura Raud Pettersson; [2022]
    Nyckelord :Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Sammanfattning : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). LÄS MER

  3. 17. Modelling and Evaluation of a Waste Incineration Flue Gas Treatment Process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sandra Arvidsson; [2022]
    Nyckelord :Flue gas treatment; Limestone wet flue gas desulphurization; FGD; Waste incineration; Scaling; Modelling; Simulation; Aspen Plus; Chemical Engineering; Technology and Engineering;

    Sammanfattning : As environmental awareness is raised, flue gas treatment is gaining more interest and stricter legislation on emissions pushes technological development. Sysav has a waste incineration plant with a flue gas cleaning process which includes removal of acid gases. LÄS MER

  4. 18. Design of a Level Sensing System for the Propellant Tank of a Microlauncher

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Robin Scholtes; [2021]
    Nyckelord :Level Sensing; Cryogenic; Microlauncher; Liquid Oxygen; Nivåavkänning; Kryogen; Mikrobärraket; Flytande Syre;

    Sammanfattning : The present report aims to show the development process of a liquid level sensing system for the use within the propellant tanks of a launch vehicle. Whereas many recent launchers use discrete level sensing systems to indicate the amount of fuel on defined spots like fill-stop and engine cut-off, in this report a continuous capacitance based sensor probe is described.

  5. 19. Usage of Natural Gas in Modern Steel-making : A Financial and Environmental Evaluation of Available Steel-making Technology in Sweden

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :William Wadbrant; [2020]
    Nyckelord :Direct Reduction; Iron sponge; Natural gas; LNG; DRI; Midrex; HYL; Electrical Arc Furnace; Blast furnace; Oxygen Converter; Capital expenditure; Modern Steelmaking; HYBRIT; Direkt reduktion; Järnsvamp; Naturgas; LNG; Hållbarhet; Koldioxidutsläpp; Växthusgaser; Midrex; HYL; Ljusbågsugn; Masugn; LD-Konverter; Kapital investering; Modern Ståltillverkning; HYBRIT;

    Sammanfattning : A method of producing steel that is not used in Sweden today is direct reduction using natural gas, a method which could has enormous potential in the future of steelmaking. Historically, steelmaking prioritized productivity and profitability. LÄS MER

  7. 20. Propellant Feeding System of a Liquid Rocket With Multiple Engines

    Master-uppsats, KTH/Rymdteknik

    Författare :Valentin Miquel; [2020]
    Nyckelord :Multiengine Feeding System;

    Sammanfattning : Multiengine first stages are the new trend in recent rockets. Reusability and an oxygen/methane based engine complete this picture. ArianeGroup wants to develop its own rocket following these principles. This thesis presents the study of the feeding system for a seven Prometheus engine rocket. LÄS MER
