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

    Author : Henrik Jilvero; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Abstract : 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). READ MORE

  2. 2. Precipitating Amine Absorption Systems for Carbon Capture

    Author : Hanna Karlsson; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Non-aqueous; AMP; Solubility; Heat of absorption;

    Abstract : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

  3. 3. Northern Permafrost Region Soil Carbon Dynamics since the Last Glacial Maximum : a terrestrial component in the glacial to interglacial carbon cycle

    Author : Amelie Lindgren; Gustaf Hugelius; Peter Kuhry; Fortunat Joos; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Soil organic carbon; Permafrost; Peat; Loess; Vegetation; Biome reconstruction; Last Glacial Maximum; Deglaciation; Glacial-interglacial cycle; Carbon cycle; naturgeografi; Physical Geography;

    Abstract : At the Last Glacial Maximum (LGM), after ~100,000 years of relatively cold temperatures and progressively lower atmospheric carbon dioxide (CO2) concentrations, CO2 levels reached ~180 ppm, which is less than half of what we see today in a much warmer world (~400 ppm). Although much of this increase since the LGM is due to human-induced emissions, about 100 ppm of this increase can be attributed to natural variations seen over glacial to interglacial cycles.

  4. 4. Oxy-Fuel Combustion Combined Cycles for Carbon Capture

    Author : Egill Maron Thorbergsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; conceptual compressor design; oxy-fuel combustion combined cycles; Graz cycle; Carbon capture and storage; Semi-closed Oxy-fuel Combustion Combined Cycle;

    Abstract : A short and medium term method to decrease carbon dioxide emissions is carbon capture and storage. This method captures carbon dioxide from point sources of emissions and then stores the carbon dioxide in geological formations. READ MORE

  5. 5. Partial carbon capture – an opportunity to decarbonize primary steelmaking

    Author : Max Biermann; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; excess heat; amine absorption; partial CO2 capture; process industry; cost estimation; CCS; steel making;

    Abstract : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. READ MORE
