  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. 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.
