  1. 1. Mapping and analysis of an internal heating network at Holmen Paper Braviken

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Ludwig Forsell; Ebba Samuelsson; [2023]
    Nyckelord :Energy mapping; Holmen paper Braviken; Internal heating network; Holmen; Energy usage in the paper industry; Energy usage for a TMP-plant;

    Sammanfattning : The pulp and paper industry is the most energy intensive industry in Sweden. Most of the energy usedaims to supply the large amount of heat to the production processes that is required to produce pulp andpaper . LÄS MER

  3. 2. Integration of an industrial heat pump for a TES-based power-to-heat system : A techno-economic assessment

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Cristian Contreras Aramayo; [2023]
    Nyckelord :Heat; electricity; industrial heat pump; power-to-heat;

    Sammanfattning : This work aims to investigate the potential electricity savings, as well as the potential decrease in LCoH and OPEX, that an integration of an industrial heat pump can have on a molten salt-based power-to-heat system with integrated thermal energy storage. The original system uses an electric heater to heat up molten salt, which acts as the heat transfer fluid of the system, from which heated steam can be produced and delivered at the output. LÄS MER

  4. 3. Phasing out peat from a co-fired 50 MWth circulating fluidized bed boiler : A theoretical sulfation potential study

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Axel Bergstrand; [2022]
    Nyckelord :Peat; corrosion; fuel mixture; CFB; circulating fluidized bed; S; alkali chlorides; Sulfur; additives; combustion; fuel design; alkali related corrosion;

    Sammanfattning : The chemical company Perstorp AB has a 50 MWth circulating fluidized bed to supply the production plant with process steam. The fuel mixture used shows a large variation with about 20 different fuel fractions that can be divided into the categories, residue wood chips, sludge, forest fuel, animal waste, industrial residues, and peat.

  5. 4. Sustainable Swedish Industry by Improved Excess Heat Recovery

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Rosengren; [2022]
    Nyckelord :Excess Heat Recovery; Black Liquor Evaporation; Pulp and Paper; Retrofit; Agenda 2030; Water Technology; Resource Management; Waste Heat; Technical Validation; Chemical Engineering; Water Savings; Energy Efficiency; Greenhouse Gas mitigation; Spillvärme; Indunstning; Svartlut; Pappersmassaindustri; Energieffektivisering; Technology and Engineering;

    Sammanfattning : Achieving a sustainable Swedish industry will require better utilization of resources already available and already spent. Nationally, vast amounts of heat are released into the atmosphere and not made use of. LÄS MER

  7. 5. Business Case, Design and Simulation of Solar Powered Hydrogen Refuelling Stations

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Axel Nordin Fürdös; [2021]
    Nyckelord :Hydrogen; HRS; Energy Systems; Technology and Engineering;

    Sammanfattning : Abstract The thesis investigates some possible pathways for how solar powered Hydrogen Refuelling Stations (Solar-HRS) can be implemented in a economically viable way. This is done by the use of a custom simulation model in MATLAB/Simulunk to simulate and evaluate the inner workings of the Solar-HRS. LÄS MER
