  1. 1. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

    Författare :Håkan Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

    Sammanfattning : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. LÄS MER

  3. 2. Gasification-based Biorefinery for Mechanical Pulp Mills

    Författare :Jie He; Per Engstrand; Wennan Zhang; Olof Björkqvist; Christoph Pfeifer; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Biofuels; Power Generation; Biomass Residues; ASPEN Plus;

    Sammanfattning : The modern concept of “biorefinery” is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various bio-based products. LÄS MER

  4. 3. GASIFICATION-BASED BIOREFINERY FOR MECHANICAL PULP MILLS

  5. 4. Integrating Biomass in Existing Natural Gas-Fired Power Plants

    Författare :Erik Pihl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

    Sammanfattning : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

  7. 5. New Opportunities and System Consequences for Biomass Integrated Gasification Technology in CHP Applications

    Författare :Åsa Marbe; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2 emissions; biomass CHP; NGCC CHP; systems analysis; biomass gasification;

    Sammanfattning : There are currently many driving forces for increasing electricity production in biomass CHP plants. This thesis presents techno-economic and CO2 emissions analyses for biomass integrated gasification technology in CHP applications. LÄS MER
