  1. 21. 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. 22. Bio-refinery system integrated with pulp and paper mills using black liquor gasification

    Författare :Muhammad Naqvi; Jinyue Yan; Mats Westermark; Klas Engvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-refinery; biomass; black liquor gasification; bio-fuel; pulp mill; CO2; coversion efficiency; integration; synthesis gas; Chemical engineering; Kemiteknik;

    Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass energy utilization. The pulp and paper industry consumes a large proportion of biomass worldwide that include bark, wood residues, and black liquor. LÄS MER

  4. 23. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances

    Författare :Karin Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefineries; system expansion; second generation biofuels; black liquor gasification; kraft pulp and paper mill; global CO2 emissions; heat integration; energy market scenarios;

    Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER

  5. 24. Analysing performance of bio-refinery systems by integrating black liquor gasification with chemical pulp mills

    Författare :Muhammad Raza Naqvi; Yinyue Yan; Chou Siaw Kiang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-refinery; Biomass; Black liquor gasification; Bio-fuel; Pulp mill; CO2; Conversion efficiency; Integration; Synthesis gas;

    Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass utilization. The pulp and paper industry consumes a large proportion of the biomass worldwide including bark, wood residues, and black liquor. LÄS MER

  7. 25. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

    Författare :Magnus Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. LÄS MER
