Abstract: Systems and methods are provided for operating a combined cycle power plant while enhancing the CO2 content of the flue gas generated by the power plant. The CO2 content is enhanced by using a combination of exhaust gas recycle and oxygen-enriched combustion. The oxygen-containing flow for performing the oxygen-enriched combustion can be generated by an integrated pressure swing adsorption process that allows for production of a commercial grade nitrogen stream (95 vol % or more of N2) while also providing an oxygen-containing stream with an oxygen content between 25 vol % and 48 vol % with high 02 recovery.
