  1. 6. Novel process integration opportunities in existing kraft pulp mills with low water consumtion

    Författare :Cecilia Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excess heat; evaporation; pinch technology; pulp and paper; energy; system consequences; process integration;

    Sammanfattning : The economic opportunities for energy savings due to process integration of the evaporation plant have proven to be good in model mills with low water consumption. This is due to the fact that the temperature level of excess heat is higher compared with pulp mills with larger water consumption. LÄS MER

  3. 7. Humidification Processes in Gas Turbine Cycles

    Författare :Marcus Thern; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Sammanfattning : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. LÄS MER

  4. 8. Metallic materials for solid oxide fuel cells and electrolysers - Mitigating high temperature corrosion

    Författare :Mareddy Reddy; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVD; High-temperature corrosion; MCO coating; Interconnect; Balance of Plant; Chromium evaporation; SOFC;

    Sammanfattning : Solid oxide cells (SOCs) are high-temperature energy conversion devices that have great potential due to their high efficiency, low operating costs, and flexibility. SOCs can produce electricity from a variety of fuels as solid oxide fuel cells (SOFCs), and they can convert electricity to fuels as solid oxide electrolyser cells (SOECs). LÄS MER

  5. 9. Simulations of Evaporation Plants in Kraft Pulp Mills: Including Lignin Extraction and Use of Excess Heat

    Författare :Marcus Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft pulp mill.; lignin extraction; heat integration; process integration; energy saving; excess heat; simulation; Energy-efficient evaporation; modelling;

    Sammanfattning : In this thesis, evaporation plants at kraft pulp mills are simulated with the purpose of making them more energy efficient. The work is important since energy saving is assumed to be one of the major solutions for handling the world's energy demand in the future. LÄS MER

  7. 10. Soil Management Strategies to Establish Vegetation and Groundwater Recharge when Restoring Gravel Pits

    Författare :Karin Palmqvist Larsson; KTH; []
    Nyckelord :groundwater protection; soil physical properties; CoupModel; unsaturated conductivity; water retention; transpiration; soil evaporation;

    Sammanfattning : The removal of vegetation and overburden changes the naturalwater purifying processes and thus decreases the groundwaterprotection in gravel pit areas. The sand and gravel depositsusedfor aggregate extraction in Sweden are also often valuablefor extraction of groundwater as a drinking water resource. LÄS MER
