  1. 1. Models for Wet Scrubbing of SO2 and NOx

    Författare :Charlotte Brogren; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limestone scrubbing; wet scrubbing; absorption; WFGD; flue gases; SO2; mass transfer; NOx; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. LÄS MER

  3. 2. Applications for Molten Carbonate Fuel Cells

    Författare :Ivan Rexed; Göran Lindbergh; Carina Lagergren; Michel Cassir; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell MCFC ; poisoning; electrolyte degradation; SO2; Electrochemical Impedance Spectroscopy EIS ; CO2 separation; button cell set-up; reversible molten carbonate fuel cell; high temperature electrolysis.; Chemical Engineering; Kemiteknik;

    Sammanfattning : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. LÄS MER

  4. 3. Conceptual Design of Semi-Closed Oxy-Fuel Combustion Combind-Cycle

    Författare :Majed Sammak; Kraftverksteknik; []
    Nyckelord :Oxy-fuel; Gas turbines; Combined Cycles;

    Sammanfattning : Accelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. LÄS MER

  5. 4. Thermal formation and chlorination of dioxins and dioxin-like compounds

    Författare :Stina Jansson; Stellan Marklund; Mats Tysklind; Jochen F. Müller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; dioxin-like compounds; isomer distribution pattern; homologue profile; injection; O2PLS; PCDD; PCDF; PCN; PCBz; PCPh; MSW combustion; formation; chlorination; flue gas; quench profiles; Environmental chemistry; Miljökemi;

    Sammanfattning : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.

  7. 5. Waste incineration residues : Persistent organic pollutants in flue gas and fly ash from waste incineration

    Författare :Eva Weidemann; Lisa Lundin; Stellan Marklund; Jean-Francois Boily; Henrik Bristav; Kees Olie; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSW; PCDD; PCDF; PCN; PCB; POP; formation; degradation; case study; flue gas sampling thermal treatment; fly ash; surface characterization;

    Sammanfattning : Modern societies produce large quantities of municipal solid waste (MSW), which is commonly disposed of by incineration. This has several advantages: it reduces the waste’s volume and sterilizes it while also enabling energy recovery. LÄS MER
