  1. 21. Investigation of carbon capture technologies for Sävenäs waste-to-energy plant

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jasmine Andersson; [2020]
    Nyckelord :CCS; flue gas treatment; waste incineration; energy balance; emission abatement;

    Sammanfattning : Carbon capture technologies have the potential to decarbonize the emissions to air from the heat and power sector and contribute to the necessary greenhouse gas emission mitigation in order to meet the Paris Agreement requirements. The energy requirement and ability to retrofit carbon capture units are crucial to convert existing power plants into more environmental benign processes to meet the Swedish national goal of greenhouse gas neutrality at 2045.

    Sammanfattning : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. LÄS MER

  5. 24. Vitalisering med biokol i urbana växtbäddar : befintliga tekniker på marknaden som kan implementeras

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Björn Skålberg; Jacob Stenlund; [2020]
    Nyckelord :biokol; biochar; växtbädd; pyrolys; jordförbättring; vitalisering;

    Sammanfattning : Biokol är en produkt med högt kolinnehåll. Upptäckten av biokol “Terra preta” kommer från Sydamerika där biokol var en restprodukt som visade sig ha mycket positiva effekter på växtligheten. LÄS MER

  7. 25. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Anton Åkervall; [2020]
    Nyckelord :DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

    Sammanfattning : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). LÄS MER
