16. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage
Master-uppsats, KTH/KemiteknikSammanfattning : 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
17. Modelling and Evaluation of a Waste Incineration Flue Gas Treatment Process
Master-uppsats, Lunds universitet/Kemiteknik (CI)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
18. Design of a Level Sensing System for the Propellant Tank of a Microlauncher
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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.

19. Usage of Natural Gas in Modern Steel-making : A Financial and Environmental Evaluation of Available Steel-making Technology in Sweden
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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
20. Propellant Feeding System of a Liquid Rocket With Multiple Engines
Master-uppsats, KTH/RymdteknikSammanfattning : 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
