  1. 16. Some aspects of adsorption in displacement washing of pulp

    Författare :Karin Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : AbstractThere are many aspects on how to improve the paper pulping process. In the washing sequence improvements to decrease the discharge to the environment can be achieved by closure of the liquid system and recycling liquid from other parts pulp process. LÄS MER

  3. 17. Industrial Bioprocess Developments for Biogas and Ethanol Production

    Författare :Karthik Rajendran; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; ethanol; process design; techno-economic analysis; simulation; modeling; Resource Recovery; Resursåtervinning;

    Sammanfattning : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. LÄS MER

  4. 18. Volumetric combustion of torrefied biomass for large percentage biomass co-firing up to 100% fuel switch

    Författare :Jun Li; Weihong Yang; Günter Scheffknecht; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; co-firing; torrefaction; torrefaction degree; kinetics; volumetric combustion; fuel switch;

    Sammanfattning : The co-firing of biomass and coal plays an important role in increasing the biomass power capacity and reducing greenhouse gas (GHG) emissions. The challenges of the large percentage biomass co-firing (over 20% on energy basis) in existing pulverized coal boilers are keeping the same steam parameters and having a high boiler efficiency and a stable operating.

  5. 19. CO2 capture from oxy-fuel combustion power plants

    Författare :Yukun Hu; Jinyue Yan; Erik Dahlquist; Mats Westermark; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; oxy-fuel combustion; flue gas recycle; evaporative gas turbine; techno- economic evaluation;

    Sammanfattning : To mitigate the global greenhouse gases (GHGs) emissions, carbon dioxide (CO2) capture and storage (CCS) has the potential to play a significant role for reaching mitigation target. Oxy-fuel combustion is a promising technology for CO2 capture in power plants. LÄS MER

  7. 20. Development of low-cost ionic liquids based technology for CO2 separation

    Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : CO2 separation plays an important role to mitigate the CO2 emissions due to burning of fossil fuels, and it is also of importance in biofuel production (e.g. biogas upgrading and bio-syngas purification and conditioning). The solvent-based absorption is the state-of-art technology for CO2 separation, where various solvents, e. LÄS MER
