| abstract |
There is disclosed a method and apparatus to reduce emissions of target emission gasses such Sulfur Oxides, Nitrogen Oxides, and Carbon Oxides from combustion exhaust such as marine engine exhaust by gas membrane separation and liquid carrier chemical absorption. The membrane separation system consists of an absorption system containing semi-permeable hollow fiber membranes through which is circulated a liquid absorbent. Exhaust gases contact the exterior surface of the membranes and the target gasses selectively permeate the membrane wall and are absorbed by the liquid carrier(s) within the bore and thereby removed from the exhaust stream. |
