Patent ID: 8104259

Claim:
A method for reducing emissions in a power plant including a gas turbine engine assembly and a carbon dioxide (CO2) separator, said method comprising: increasing an operating pressure of an exhaust stream discharged from the gas turbine engine assembly; reducing an operating temperature of the exhaust stream; substantially reducing a concentration of CO2 entrained within the exhaust stream utilizing the CO2 separator to produce a CO2 lean exhaust stream; reducing the operating temperature of the CO2 lean exhaust stream; channeling the cooled CO2 lean exhaust stream through a first flow path of a heat exchanger to reduce an operating temperature of a flow of ambient air channeled through a second flow path of the heat exchanger prior to entering the gas turbine engine assembly wherein the first and second flow paths are coupled in thermal communication and isolated in flow communication with respect to each other; substantially removing moisture entrained in the gas turbine engine inlet airflow utilizing a desiccant air drying system; and channeling the relatively dry air discharged from the desiccant air drying system through a heat exchanger.
