  2. 21. Lignin Extraction from Black Liquor - Precipitation, filtration and washing

    Author : Henrik Wallmo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filtration; Precipitation; Washing; Lignin; Absorption; Separation; LignoBoost.; Black liquor;

    Abstract : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. READ MORE

  4. 22. Selection of oxygen carriers for chemical-looping combustion using methane as a fuel

    Author : Marcus Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Capture; Nickel oxide; CO2 Separation; Oxygen Carrier; Iron oxide; Manganese oxide.; Chemical-Looping Combustion;

    Abstract : In order to meet new demands on clean energy producing technologies, chemical-looping combustion could play an important role. With this technique, CO2 from the flue gases can be separated and collected without excessive energy and efficiency penalty. This is because nitrogen from the combustion air is never mixed with the fuel. READ MORE

  6. 24. Thermodynamic Analysis and Screening ILs/DESs-based Absorbents for CO2 Separation

    Author : Yingying Zhang; Xiangping Zhang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation plays an important role in both biofuel production, and CO2 capture and storage (CCS) implementation to deal with global warming. The available CO2 separation technologies are either energy-intensive or require large-scale operations, and it is crucial to develop novel CO2 separation technology in order to optimize the energy uses and the amounts of CO2-absorbents/adsorbents.

  7. 25. CO2 Separation - from Aqueous Amine Solvent to Ionic Liquid-based solvent

    Author : Nan Wang; Xiaoyan Ji; James Glynn; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation is one of the most important roles in CO2 mitigation target as many human production activities (e.g., cement, iron and steel, and biogas productions) cause CO2 emissions. The solvent-based absorption is the most mature technology for CO2 separation, where different solvents capture CO2 either in chemical or physical absorptions. READ MORE
