  1. 1. Isocyanates formation from thermal degradation of polyurethane foam during welding of district heating pipes

    University essay from KTH/Ergonomi

    Author : Muhammad Akram; [2023]
    Keywords : Polyurethane; Isocyanates; District Heating Pipes; Oxy-fuel Welding; Manual Metal Arc Welding;

    Abstract : Polyurethane insulation foam, which is used as insulation on district heating steel and copper pipes, is made from polymerisation of polyol and diisocyanates monomers. Installation of new district heating pipes or replacement of old pipes involves masses of welding activities. READ MORE

  3. 2. Modification of lignin derivatives for polymerization in water

    University essay from KTH/Ytbehandlingsteknik

    Author : Adrian Södergren; [2022]
    Keywords : biobased monomer; ferulic acid; radical polymerization; styrenic mononer; lignocellulose; biobaserad monomer; ferulsyra; radikalpolymerisation; styrenliknande monomer; lignocellulosa;

    Abstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

  4. 3. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    University essay from KTH/Kemiteknik

    Author : Laura Raud Pettersson; [2022]
    Keywords : 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;

    Abstract : 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). READ MORE

  5. 4. Climate Neutral Roadmap in Fossil Free Competitiveness for Paroc, Sweden : what Paroc can do to meet up with the roadmap from Fossil Free Sweden

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Felix Mörk; [2021]
    Keywords : Climate neutral; Fossil free; Mineral wool; Competitiveness; Intercommunion; Plasma burner; Oxy fuel; Hydrogen gas.;

    Abstract : Today’s society is standing in front of a revolution where fossil energy should be replaced with renewable energy. Governmental agencies and policy makers have formed goals and regulations to become greener, and the organisation Fossil Free Sweden has published roadmaps for fossil free competitiveness. READ MORE

  6. 5. Power and Methanol Production from Biomass Combined With Solar and Wind Energy : Analysis and Comparison

    University essay from KTH/Kraft- och värmeteknologi

    Author : Husni Firmansyah; [2018]
    Keywords : ;

    Abstract : The purpose of this work is to investigate the feasibility of an integrated system consisting of biomass-based power generation built-in with carbon capture technology combined with a water electrolysis unit operated by solar cells and wind turbines to produce fuel through the methanol synthesis process. The configurations are examined both technically and economically to determine their feasibility, and subjected to sensitivity analysis to determine their economic viability and optimum performance.
