  1. 1. Status Mapping of tank to grave management of Low-GWP refrigerants.

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

    Författare :Sandra Parra Gimeno; [2023]
    Nyckelord :Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER

  3. 2. Desulphurisation of cement flue gases

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ellen Sjöstrand; [2023]
    Nyckelord :Flue Gas Desulphurisation; FGD; gypsum; cement;

    Sammanfattning : Flue gas desulphurisation (FGD) is a crucial method to minimise the SO2 emissions from industrial processes. The FGD system utilise an alkaline sorbent to remove SO2 from the flue gases. Calcium in form of limestone is a commonly used sorbent where gypsum is produced asa by-product. LÄS MER

  4. 3. Top European electricity producers´eco-efficiency : And the role of policy instruments

    Master-uppsats, Umeå universitet/Nationalekonomi

    Författare :Matilda Hahne; [2022]
    Nyckelord :;

    Sammanfattning : There is an implicit trade-off between environmental quality and the production of goods which can be analysed using an eco-efficiency approach. Within an eco-efficiency approach, Decision Making Units (e.g. LÄS MER

  5. 4. MEASURING ECO-EFFICIENCY OF PRODUCTION IN OECD MEMBER COUNTRIES : A STOCHASTIC FRONTIER ANALYSIS

    Master-uppsats, Umeå universitet/Nationalekonomi

    Författare :Mahmoud Seif Mohammed; [2022]
    Nyckelord :;

    Sammanfattning : This paper analyzed the eco-efficiency of 27 OECD member countries by using output-oriented Stochastic Frontier Analysis (SFA) model. In the set-up of the model, Gross Domestic Product (GDP) was used as a good output whereas Carbon dioxide (CO2), Sulphur dioxide (SO2) and Nitrogen oxide (NOx) emissions were used as bad outputs.

  7. 5. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linus Brakebusch; [2022]
    Nyckelord :sedimentology; geochemistry; ooids; oolites; oncoids; oncolites; Triassic; Jurassic; Rhaetian; Hettangian; ocean acidification; Earth and Environmental Sciences;

    Sammanfattning : The end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea. LÄS MER
