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

    Författare :Karin Pettersson; [2011]
    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

  2. 17. Online characterization of wood pulp foundations for a photoacoustic sensing technique

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jan Niemi; Luleå tekniska universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    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

  3. 18. Process Industry Energy Projects in a Climate Change Conscious Economy

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Anders Ådahl; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process Integration; pulp mill; Nordic countries; energy market; climate policy; CO2; energy savings; biofuel;

    Sammanfattning : Most industrial process plants consume large amounts of energy (usually in the form of steam and electricity) to produce demanded goods, such as beer or paper. However, combustion of fossil fuels has negative external effects on the Earths climate. LÄS MER

  4. 19. Appropriation by Coloniality TNCs, land, hegemony and resistance. The case of Botnia/UPM in Uruguay

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Adrián Groglopo; Umeå universitet.; [2012]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transnational corporations; foreign direct investments; foreignization of land; Latin America; pulp; hegemony; resistance; social movements; sociologi; Sociology;

    Sammanfattning : The overall aim of this thesis is to analyse the social consequences of a transnational corporation(TNC) from the global North investing capital in the global South, and the communal processes that evolve in response. The study highlights the TNC’s construction of leadership and domination in the areas in which it settles, as well as the forces of popular resistance to the TNC’s exploitation of the region’s natural resources and the resulting socio-environmental conditions.

  5. 20. Aspects on Strenght Delivery and Higher Utilisation of the Strength Potential of Kraft Pulp Fibres

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Elisabet Brännvall; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Sammanfattning : Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. LÄS MER
