Marine Exhaust Emissions Control
Exhaust gases from engines and boilers contain atmospheric pollutants
which are principally nitrogen oxides (NOX), sulphur oxides (SOX),
carbon oxides and unburnt hydrocarbon particulates. These various
pollutants contribute to smog (smoke+fog) and acid rain, and carbon oxides
contribute to the greenhouse effect, which is increasing global
temperatures.
The IMO Marine Environment Protection Committee is considering ways to reduce the pollutants in exhaust emissions. The SOX content of emission may be reduced by either a reduction of the sulphur content in fuels or an exhaust gas treatment system. New engine technology may reduce NOX formation and thus emissions, while carbon oxides can be reduced by good plant maintenance.
