  1. 16. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Frida Nilsson; [2023]
    Nyckelord :CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

    Sammanfattning : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. LÄS MER

  3. 17. 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

  4. 18. Biodrivmedelsproduktion i Sverige: Utvecklingen av svenska styrmedel och politiska mål

    Master-uppsats, KTH/Kemiteknik

    Författare :Viktor Kjellvertz; [2023]
    Nyckelord :Biofuel policy; Biofuel quota duties; Energy- and environmental policy goals; Biofuel production; Swedish biofuels; Biodrivmedelspolitik; Reduktionsplikt; Energi- och miljöpolitiska mål; Svensk biodrivmedelsproduktion; Svenska biodrivmedel;

    Sammanfattning : I det här examensarbetet har utvecklingen av den svenska politiken kring biodrivmedel under perioden 1975–2020 undersökts. Detta i syfte att öka förståelsen för de politiska motiv som legat till grund vid utformningen av politiska styrmedel samt hur sambanden mellan styrmedel och biodrivmedelsproduktion utvecklats.

  5. 19. Metodik för framtagande av konsekvenskartor för klimatanpassad dagvattenplanering

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Vendela Karlsson; [2023]
    Nyckelord :Consequence mapping; Consequence analysis; Flooding; Stormwater management; QGIS; Water and Environmental Engineering; Technology and Engineering;

    Sammanfattning : The extreme short-term precipitation in Sweden is expected to increase due to climate change. This means that there will be an increased risk of floodings in urban areas. Several cloudbursts during the past decade have caused major damage to communities all over Sweden with high restoration costs as a result. LÄS MER

  7. 20. FTIR mätningar av absorptionsvätskor i Bioenergy Carbon Capture and Storage processer

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Isa Pettersson Haag; Emma Hedberg; Oliver Svahn; David Danielsen; [2023]
    Nyckelord :BECCS; FTIR; carbon dioxide; carbonate; bicarbonate; PCA;

    Sammanfattning : The effects of global warming are well understood. In order to combat this, society must move towards net zero emissions of green house gases, where carbon dioxide (CO2) plays a key role. In several IPCC climate scenarios that meet the Paris agreement, negative emission technologies that effectively remove CO2 from the atmosphere are included. LÄS MER
