Patent ID: 7861511

Claim:
A system of reducing the constituents within an exhaust stream generated by a turbomachine, the system comprising: a total exhaust stream operatively generated by the turbomachine having an inlet, a compressor, an external combustion system, an exhaust section, and a turbine section, wherein the exhaust stream is a portion of the total exhaust stream exiting the turbomachine; an exhaust gas recirculation (EGR) system integrated with the turbomachine and containing a scrubber that: receives the exhaust stream containing constituents at a first level at a first temperature from the turbomachine exhaust section; reduces the exhaust stream temperature to below the saturation temperature of the exhaust stream; reduces the constituents to a second level; sequesters and removes concentrated CO2 from the exhaust stream; outputs the exhaust stream at a second temperature; and re-circulates the exhaust stream exiting the scrubber to the inlet of the turbomachine; a heat exchanger upstream of the EGR system, the heat exchanger receiving the exhaust stream, reducing the temperature of the exhaust stream, and directing the exhaust stream to flow to an inlet portion of the scrubber; a demister located downstream of the heat exchanger that removes water from the exhaust stream; and a mixing station located upstream of the turbomachine inlet that mixes the exhaust stream with inlet air entering the turbomachine inlet.
