SOx Abatement

• SOx are various oxides of sulphur, in particular SO2 and SO3 derived from the burning of sulphur embedded in fuel.
• SOx emissions have been shown to affect human health and acidification of groundwater
• Since there is a direct relationship between the sulphur content of the fuel and the sulphur content within untreated exhaust gas, legislation has generally been framed around limiting the sulphur content of fuel
• International legislation (IMO MARPOL Annex VI) and regional legislation (EU Directive 1999/32) limits the SOx that ships may emit, and abatement technologies may be used by ships to achieve these required emissions reductions
