  1. 1. Ammonia-Based Post-Combustion Capture of Carbon Dioxide

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; Ammonia; Post-combustion;

    Sammanfattning : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. LÄS MER

  3. 2. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER

  4. 3. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

    Författare :Peng Li; Lidong Teng; Sankaran Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal diffusivity; Model; Solubility; CO2; AlN; Crystals; Hydrolysis; Enhance; Hinder; Leaching; Absorption; Synthesis; SiMgAlON; Oxidation; Arctan; Activation energy; Mullite; Liquid; Crystallization.; SRA - Production; SRA - Produktion;

    Sammanfattning : To offer better solutions for the recycling of salt cake from secondary aluminum melting, several innovative investigations were carried out based on hydrometallurgical and pyrometallurgical views.Thermal diffusivity measurements as a function of temperature on salts-Al composites having various compositions (0, 2, 4, 6, 8, 10, 12wt pct metallic Al) were carried out.

  5. 4. Renewable gas in a Swedish context

    Författare :Laura Malek; Avdelningen för kemiteknik; []
    Nyckelord :synthetic natural gas; biomass; gasification; gas grid; techno-economic; tar; ammonia;

    Sammanfattning : In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. LÄS MER

  7. 5. Development and Application of Methods based on DOAS and FTIR Absorption Spectroscopy for Atmospheric Research

    Författare :Bo Galle; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; open-path; nitrous oxide; DOAS; long-path absorption; landfill; methane; climate gases; ozone depletion; biogenic emissions; fugitive emissions; FTIR; ammonia;

    Sammanfattning : Over the past decades concern about the environmental impact on our atmosphere from human activities has been constantly increasing. From the recognition of local industrial pollution in the first part of this century, over regional scale problems related to urbanisation and growth of traffic systems to global environmental problems such as climate change and stratospheric ozone depletion.
