Movable emission control system for auxiliary diesel engines

Abstract

A mobile emissions control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system comprises two essential elements: an emissions capturing system and an emissions control system. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. The emission capturing system captures exhaust from a ship's diesel engine and conducts it into the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.

What is claimed is: 
     
         1 . A method for reducing emissions from a ship's exhaust, the method comprising the steps of:
 (a) providing an emissions capturing system having a duct for capturing the ship's exhaust for treatment; and   (b) connecting the emissions capturing system to an emissions control system positioned within a housing having an upper and lower level, where the emissions control system has an exhaust inlet for receiving diesel engine exhaust and an exhaust outlet for emitting reduced emissions exhaust, a filter housing, and at least one waste catch positioned on the lower level.   
     
     
         2 . The method of  claim 1 , where the emissions control system is mounted on a chassis. 
     
     
         3 . The method of  claim 1 , where the emissions control system is mounted on a barge. 
     
     
         4 . The method of  claim 1 , where the emissions capturing system includes a crane that extends the duct over the ship to capture the ship's exhaust. 
     
     
         5 . The method of  claim 1 , where the emissions control system incorporates a filter housing. 
     
     
         6 . The method of  claim 1 , where the emissions control system incorporates a primary reactor and a secondary reactor for treating the emissions from the ship's exhaust. 
     
     
         7 . The method of  claim 1 , where the emissions control system incorporates an algae bioreactor.
