CO2 concentration enhancement method in exhaust gas by supplying oxygen to the gas engine

Abstract

Oxygen additional system was examined for CO2 capture system in gas fueled engine. In this study, the effect of the oxygen supply on combustion was investigated to increase CO2 concentration of the exhaust gas. As the amount of supplied oxygen increased, the more EGR was required for the higher thermal efficiency. Exhaust temperature increased as the amount of supplied oxygen increased under same G/F condition. The supplied oxygen could increase the CO2 concentration and the temperature of the exhaust gas.
