1. 6. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anna Wagne; [2023]
   Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER

3. 7. 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

4. 8. Assessment of the integration of solar heat power into food drying processes

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Charalampos Psilopoulos; [2023]
   Nyckelord :Sustainable; sustainability; co2 reduction; feasibility; solar thermal; direct steam generation; drying; food industry; scope 1 emissions; sdg; sustainable development goals; spray drying; drum drying; powder; food; Technology and Engineering;

   Sammanfattning : The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit significant amounts of Greenhouse Gases (GHGs).

5. 9. Negative Emission from Electric Arc Furnace using a Combination of Carbon capture and Bio-coal

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

   Författare :Abhijith Namboodiri Kapothanillath; [2023]
   Nyckelord :EAF; Off-gas handling; CCS; Calcium Looping CaL ; Post-combustion; Waste heat recovery; Bio-coal; Negative emissions; Techno-economic analysis; EAF; Avgasrening; CCS; Calcium Looping CaL ; Efterförbränning; Återvinning av spillvärme; Biokol; Negativa utsläpp; Teknisk-ekonomisk analys;

   Sammanfattning : Steel is one of the most essential metals in the world, and it plays a vital role in various industries. The growing demand for steel has resulted in increased CO2 emissions, with the steel industry contributing to approximately 7% of global emissions of carbon dioxide. LÄS MER

7. 10. 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
