  2. 11. Models for Wet Scrubbing of SO2 and NOx

    Author : Charlotte Brogren; Avdelningen för kemiteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 12. NOx Formation in Rotary Kilns for Iron Ore Pelletization

    Author : Rikard Edland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; combustion chemistry; emissions control; Grate-Kiln process; Nitrogen oxides; NOx formation;

    Abstract : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. READ MORE

  5. 13. An Investigation of Low Temperature Combustion Using high Levels of EGR

    Author : Malin Alriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low soot; low NOx; low temperature combustion; emissions; diesel combustion;

    Abstract : The diesel engine offers good fuel economy and generates low carbon dioxide (CO2) emissions, but it is also a source of undesirably high particulate matter (PM) and nitrogen oxide (NOx) emissions, which are subject to increasingly strict legislative limits because of their adverse effects on the environment and human health. Thus, in recent years, several combustion concepts have been developed to meet future legislation requirements, one of which is Low Temperature Combustion (LTC) using high levels of EGR (Exhaust Gas Recycling).

  6. 14. Remote Measurements of Ship Emissions

    Author : Niklas Berg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

    Abstract : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. READ MORE

  7. 15. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

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

    Abstract : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. READ MORE
