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

    Author : Henrik Jilvero; Chalmers tekniska högskola; []
    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

  4. 7. Experimental Studies on CO2 Absorption in Hollow Fiber Membrane Contactor

    Author : Yuexia Lu; Jinyue Yan; Niklas Hedin; Mälardalens högskola; []
    Keywords : CO2 capture; Hollow fiber membrane contactor; Membrane gas absorption; Partial wetting; Surface modification; ; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Membrane gas absorption technology is considered as one of the promising alternatives to conventional techniques for CO2 separation from the flue gas of fossil fuels combustion. As a hybrid approach of chemical absorption and membrane separation, it may offer a number of important features, including operational flexibility, compact structure, linear scale up and predictable performance.

  5. 8. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Author : Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Abstract : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. READ MORE

  6. 9. Post-Combustion CO2 Capture in Kraft Pulp Mills - Technical, Economic and System Aspects

    Author : Erik Hektor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical absorption; Excess heat; Post-combustion; Chilled ammonia; Process integration; Mono-ethanolamine; Pulp and paper; CO2 capture;

    Abstract : As a result of increasing concerns about climate change, there is considerable research and activities around CO2 capture and storage. In this thesis it is studied what role the pulp and paper industry can play in mitigating climate change through CO2 capture and storage. READ MORE

  7. 10. Ammonia-Based Post-Combustion Capture of Carbon Dioxide

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

    Abstract : 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. READ MORE
