METHODS OF REDUCING HARMFUL POLLUTANT EMISSIONS FROM SHIPS
Kristijan Lenac
Abstract
This paper outlines methods used for reducing emission of air pollutants such as: nitrogen oxides, sulfur oxides, particulate matter, carbon monoxide, carbon dioxide and volatile organic compounds from ships. These methods can be separated into two major groups: primary and secondary. Primary methods consist of different tehnical solutions that prevent producing of air pollutants in the engine, while secondary methods neutralize the air pollutants that have already emerged. Primary methods are: modifications of the combustion system and air system, direct water injection, exhaust gas recirculation, fuel and water emulsion. Secondary methods are: selective catalytic reduction, low sulfur fuels, plasm system of reducing air pollutant emission.
