  1. 1. Mercury and dioxins in a MercOx-scrubber

    Författare :Carl-Johan Löthgren; Bert Allard; Bert van Bavel; Sven Andersson; Ivars Neretnieks; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waste incineration; flue gas cleaning; PCDD PCDF; PBDD PBDF; wet scrubber; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : The removal of mercury and the absorption of dioxins in an acid wet scrubber have been studied in industrial scale. Hydrogen peroxide is added as an oxidizing agent to the scrubber liquid with the purpose to remove SO2 and enhance the removal of mercury. LÄS MER

  3. 2. 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

  4. 3. The chemistry of organic iodides under severe nuclear accident conditions in LWRs

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic iodides; Wet-filter system scrubber ; Chlorine; Volatile iodine source term; Severe nuclear accident; Cables; Sorption; Containment; Paint; Iodine; LWR; Radiolysis;

    Sammanfattning : For many countries nuclear fission is an important part of their energy portfolio. However, a great concern is the occurrence of nuclear reactor accidents, which can result in the emission of radioactivity into the environment. LÄS MER

  5. 4. Upscaling and Evaluation of Absorption Based Systems for Co-removal of NOx and SOx from Flue Gases

    Författare :Jakob Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption; gas-phase oxidation; scale-up; Emissions control; SOx; NOx; ClO2;

    Sammanfattning : As long as combustion remains a vital part of the energy system, the removal of nitrogen oxides (NOx) will be a challenge that will need to be addressed. In addition, emissions of sulfur oxides (SOx) will be a problem as long as fuels such as coal and oil are used, as is envisaged in every road map suggested by the Intergovernmental Panel on Climate Change (IPPC).

  7. 5. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions

    Författare :Sabrina Tietze; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxy paint; Methyl iodide; Iodine source term; Organic iodides; Severe nuclear accidents;

    Sammanfattning : During severe nuclear reactor accidents such as Chernobyl or Fukushima large amounts of radioactive iodine can be released in form of inorganic and organic iodine species into the environment. Volatile radioactive iodine species are harmful to human health when inhaled. LÄS MER
