  1. 1. Displacement Washing in the Sulfate Pulp Mill

    Författare :Gunnar Eriksson; Chalmers University of Technology; []
    Nyckelord :metal ions; Kraft pulp; models; diffusion; filter cakes; sorption; temperature; lignin; fibers; washing; lime mud; chemical recovery; displacement; pulp washing;

    Sammanfattning : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. LÄS MER

  2. 2. Bonding Ability Distribution of Fibers in Mechanical Pulp Furnishes

    Författare :Sofia Reyier; Per Engstrand; Hans Höglund; Olof Ferritsius; Hans Ersson; Rita Ferritsius; Philip Reme; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; mechanical pulp; bonding ability; fiber characterization; Bonding Indicator; BIN; acoustic emission; hydrocyclone; Fiberlab; collapse resistance; fibrillation; Fiber; mekanisk massa; bindningsförmåga; fiber karakterisering; Bindnings Indikator; BIN; akustisk emission; hydrocyklon; Fiberlab; kollaps resistans; fibrillering; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : This thesis presents a method of measuring the distribution of fiber bonding ability in mechanical pulp furnishes. The method is intended for industrial use, where today only average values are used to describe fiber bonding ability, despite the differences in morphology of the fibers entering the mill. LÄS MER

  4. 4. Process integration studies on Kraft pulp-mill-based biorefineries producing ethanol

    Författare :Rickard Fornell; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kraft pulp mill; Ethanol; Energy; Process integration; Biorefinery;

    Sammanfattning : Large scale, sustainable production of biofuels will require commercialization ofprocesses using lignocellulosic feedstocks. These processes are still notcompetitive with existing pathways, however. The competitiveness oflignocellulosic biofuel production plants could potentially be improved if theywere integrated with already existing facilities. LÄS MER

  5. 5. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill

    Författare :Magnus Karlsson; Lars J. Nilsson; Linköpings universitet; []
    Nyckelord :MIND; Industrial energy systems; Investment; pulp and paper; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. LÄS MER
