  1. 16. 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

  3. 17. Oxidation of Kraft Pulp Fibres - Hydrogen Peroxide Oxidation under Acidic Conditions and its Influence on the Properties of Pulp

    Författare :Axel Martinsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An increase in the use of bio-based products, combined with a decrease in the use of fossil-based products, is important for fulfilling the demands of a growing population in a sustainable manner. Moreover, reducing the usage of single-use plastics is vital in combating the plastic pollution that is afflicting our environment. LÄS MER

  4. 18. Flow and Rheology of Pulp Suspensions at Medium Consistency

    Författare :Tomas Wikström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluidisation; yield stress; agitation; pulp suspension; computational fluid dynamics; fibre properties; turbulence; screening; Bingham model;

    Sammanfattning : Traditionally, development of pulp processing equipment has been based on the accumulation of qualitative knowledge (experience) with respect to the interaction of equipment and pulp suspensions. This way of developing equipment requires several trials and prototypes before the final product and process data can be established. LÄS MER

  5. 19. 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

  7. 20. Online characterization of wood pulp : foundations for a photoacoustic sensing technique

    Författare :Jan Niemi; Mike Somekh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Today, there is an increasing demand in the paper industry for better utilisation of the raw material and improved energy efficiency. Also, the increasing use of recycled paper in the manufacturing process leads to a situation where the knowledge of pulp properties needs to be improved and controlled. LÄS MER
