  1. 11. Experimental assessment of properties for a non-aqueous and precipitating alkanolamine absorption system

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Robertsson; [2022]
    Nyckelord :AMP; DMSO; CCS; BE-CCS; Viscosity; Density; Freezing Temperature; Chemical Engineering; Technology and Engineering;

    Sammanfattning : With increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt crystals with CO2.

  3. 12. Carbon dioxide-based pump system for portable HPLC equipment

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Sofia Göransson; [2022]
    Nyckelord :Microsystem Technology; Flow Chemistry; Chemical Analyses; High-Performance Liquid Chromatography; HPLC; Pump System; Miniaturise; Portable; Pressurised Carbon Dioxide; PCO; High-Pressure;

    Sammanfattning : To make chemical analysis available both practically and economically, one approach is to miniaturise the equipment needed for the analysis. High-performance liquid chromatography (HPLC) is an example of a flow chemistry analysis system where active work is performed to achieve miniaturised systems. LÄS MER

  4. 13. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Simone Facchini; [2022]
    Nyckelord :organic chemistry; membranes; isatin; polymers; Chemistry;

    Sammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER

  5. 14. 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

  7. 15. Integrating CO2 Utilisation and Biomass Gasification with Steel-making Electric Arc Furnaces (EAF)

    Master-uppsats, KTH/Energiprocesser

    Författare :Adel Mokhtari; [2022]
    Nyckelord :biomass gasification; carbon capture and utilization CCU ; process integration; electric arc furnace EAF ; EAF off-gas;

    Sammanfattning : Without a doubt, there is a consensus around the international community which suggests that our current way of life is unsustainable for a healthy planet, society and economy. One focal point that should be taken deeply into consideration is the steel industry as, globally, it accounts for 8% of global emissions. LÄS MER
