Marine Diesel Engine SO2 Scrubbers

In 2010 I blogged about a Marine Scrubber system to remove SO2 from marine diesel engine exhaust gas.  This month, Envitech completed a 3MW marine diesel engine SO2 scrubber that will be used to clean the stack gases of ships while at dock at the Port of Long Beach, CA.Marine Scrubber   The scrubber will be used for the Advanced Maritime Emissions Control System (AMECs) by Advanced Cleanup Technologies, Inc..    The system will undergo duration tests at the port during 2012 and 2013 with the goal of obtaining a verification certificate by the California Air Resources Board (CARB). 

The AMECs system is a stationary system that uses a bonnet to capture the exhaust gas from the ships stack while at port. The exhaust gases are conveyed to the AMEC system to clean the gases of particulate (PM), NOx and SOx before exhausting to atmosphere. This allows the ship to operate its auxiliary engines and boiler system while at port to provide power to the ship.  The AMECs system provides a cost effective way for ships and port operators to reduce emissions and to meet tougher regulatory standards. 

In a parallel track, the maritime industry is looking for ways to meet tougher standards not only at port but while operating at sea based on the IMO Annex VI MARIPOL Tier III requirements. Envitech continues to develop De-SOx technology options for ship based marine diesel engines.  We are currently building a 3MW marine diesel SO2 scrubber system that will be used in a demonstration unit for a complete after treatment system for SOx and NOx. The system will undergo validation testing in a state of the art marine engineering facility.  Testing will begin before the end of this year.
