Influence of Ecological Requirements on Choice of Equipmentfor Treatment of Hot Gases Emissions from Ship's Power Plants

Control of air pollution caused by ships power plant and its reduction to the desired limits can be achieved by various ways. One of the most significant and acceptable at this stage of today’s technological development is the catalytic converter operating on the principle of the selective catalytic reduction (SCR). Considering air pollution from ships, circumstances are rather complex. Namely, the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78) in addition to the general and common rules concerning every kind of pollutants anticipated specific provisions in the Annexes. At present, only local and partial laws are in forces, which are valid in the whole trading area (zone of economic interest) up to 200 Nm off the coast, with a requirement for ships built after 1995 to be fitted at least with a Selective Catalytic Reduction System (SCR).
