  3. 17. Particle Emissions from Ships

    Författare :Maria Zetterdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LNG; marine fuel; fuel sulphur content; particle emission; sulphur emission control area; aromatics; SECA; heavy fuel oil; marine diesel oil; liquefied natural gas; ship emission;

    Sammanfattning : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. LÄS MER

  5. 19. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008

    Författare :Erik Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IMO; SOx; global cap; Annex VI; MARPOL; air pollution; ships; sulphur oxides; policy-making; emissions;

    Sammanfattning : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

  7. 20. Remote Measurements of Ship Emissions

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

    Sammanfattning : 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. LÄS MER
