  1. 1. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol

    Författare :Rickard Fornell; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; energy efficiency; process integration; biofuels; kraft pulp mill; ethanol;

    Sammanfattning : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. LÄS MER

  2. 2. Analysing different technology pathways for the pulp and paper industry in a European energy systems perspective

    Författare :Johanna Jönsson; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology pathways; pulp and paper industry; energy market scenarios; biorefinery; kraft pulp mill; global CO2 emission;

    Sammanfattning : For the pulp and paper industry (PPI), earlier research has shown that there are many technology pathways, proven and new, available for improvement of energy efficiency and additional sales of (new) products. Some pathways can only be implemented in kraft mills, e.g. black liquor gasification (BLG), but some can be implemented industry-wide, e. LÄS MER

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

    Detta är en avhandling från Sundsvall : FSCN - Fibre Science and Communication Network

    Författare :Sofia Reyier; Mittuniversitetet.; [2008]
    Nyckelord :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; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik 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. Fish diseases and pulp mill effluents : epidemiological and histological studies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Rickard Fornell; [2012]
    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
