Green Shipping: Abatement of Marine Engine Emissions Using an Integrated Catalyst/Srubber Technology

In the present contribution we report results concerning the abatement of emissions of marine engines which is of a major concerns in terms of contribution to the total emissions due to transportation. A combined catalytic/scrubber technology capable of effectively reducing NOx, SOx, HC, CO and PM emissions from a marine engine is described. The system has been first investigated in a laboratory micro- plant and to obtain necessary data to dimension a real prototype (1.5MW engine power). The real plant has been used for over one month period studying the effects of S-content and engine load conditions. Very high SOx, PM, HC, CO and substantial NOx conversions have been obtained, showing the feasibility of this integrated technology for marine engines. The advantages and the drawbacks will be discussed
