STUDY OF THE POSSIBILITY OF PRACTICAL APPLICATION OF THE METHOD OF MARINE ENGINES EXHAUST GAS CLEANING BY SOLID ADSORPTION IN THE PRESENCE OF OZONE
To improve the ecological safety of ship power plants, the methods of ship engine exhaust gas cleaning are considered. It was established that the purification of ship power plants exhaust gases from harmful impurities, especially nitrogen oxides, can be realized by the oxidation of nitrogen oxide to nitrogen dioxide by adsorption, proceeding in parallel with the condensation of the water vapor of the exhaust gases formed during combustion of fuel in the diesel cylinder, or boiler furnace. A complex device for marine engine exhaust gas cleaning is developed. As an adsorbent for harmful exhaust components, granulated slag pumice is used, while ozone is used as an oxidizer to accelerate the cleaning process. The experiment made for the purpose of check of the complex cleaning device operability and an assessment of its efficiency proved the possibility of practical usage of the studied cleaning method.
