Development of DeNO{sub}x system for marine diesel engine by SCR with liquid hydrocarbon

摘要

The exhaust gas of marine diesel engine contains a lot of NO{sub}x, SO{sub}x and PM, that is, it contributes to global warming and air pollution, and the IMO has regulated the NO{sub}x emissions for the vessels built after January 1st, 2000. KHI has the experience of research about DeNO{sub}x methods, for example, timing retard, EGR, fuel-water emulsion, natural gas and methanol ignited with pilot fuel oil, and SCR with NH{sub}3 or HC. This paper introduces the test results of DeNO{sub}x system for marine diesel engine by SCR with liquid hydrocarbon extracted from marine diesel oil, which has the advantage in cost, treatment and supply compared with troublesome N113 system.
