ABSTRACT:
A method for operating a power plant to facilitate reducing emissions, wherein the power plant includes a gas turbine engine assembly and a carbon dioxide (CO2) separator. The method includes increasing an operating pressure of exhaust gas discharged from the gas turbine engine assembly, separating substantially all the CO2entrained within the gas turbine engine utilizing the CO2separator to produce a CO2lean airstream, reducing the operating temperature of the CO2lean airstream, and utilizing the cooled CO2lean airstream to facilitate reducing an operating temperature of air entering the gas turbine engine assembly.
