Abstract Information :

Recognition of the needs to prevent and control pollution from industries is widespread for environmental protection. Regarding the marine and shipping industries, International Maritime Organization (IMO) has been regulating deliberate, negligent or accidental release oil and other harmful substances from ships by MARPOL 73/78convention.Especially, NOx and SOx emissions emitted form ships are restricted by Annex VI of the convention. Although particulate matter(PM) formed by incomplete combustion of fuel has been indirectly regulated by sulphur contents of fuel oil, Recently, direct regulation of particulate emission (especially black carbon (BC)) has been discussing at Marine Environment Protection Committee (MEPC) of IMO. In this respect, the wet electrostatic precipitator (Wet EP) developed for reducing Black Carbon and performance test of the wet EP was carried out using a low speed marine diesel engine (7,400 kW at 129 rpm) in this study. And the reduction rate of BC emission was calculated by comparing BC measured value between engine-out emission and downstream of Wet EP system. Two analysers, which are smoke meter and micro soot sensor (MSS), mentioned at the IMO committee, were used for BC measurements. The results revealed that reduction rate of BC emission, which are represented in Filter Smoke Number and soot concentration, was over 90 %. From these results, we confirmed that the possibility of application wet electrostatic precipitator in marine low speed two stroke engine for BC abatement technology.
