First operational experiences with a combined Dry Desulphurization Plant and SCR Unit downstream of a HFO fueled marine engine
In December 2011 Couple System has successfully managed the commissioning of a Dry Scrubber (DryEGCS) in combination with a SCR catalyst. The application consists of an engine test bed on which marine diesel engines up to an output of 24 MW are running. The exhaust gases of the HFO fueled engine are fed into the dry scrubber named DryEGCS where the exhaust gas is cleaned off of SOx in a magnitude of more than 99 %. Particles are removed in excess of 90 %. The temperature of the exhaust gas is maintained and represents the optimum temperature for the reduction of nitrogen oxides by the SCR catalyst. The SCR process requires the injection if ammonia which in this case is done in the form of an aqueous ammonia solution. The installed SCR system is one of the largest systems operated downstream of a marine diesel engine. The combined DeSOx and DeNOx system meets all present and future IMO regulations including a potential PM regulation. The entire system is monitored by a continuous monitoring system according to scheme B (MEPC.1849). The paper includes a full technical description as well as operational data.
