Abstract

Methods and systems for CO2 separation for low emission power production in combined cycle power plants are provided. One system includes a gas turbine system that stoichiometrically combusts fuel and oxidant in the presence of a compressed recirculation stream to provide mechanical power and gaseous exhaust. The compressed recycle stream acts as a diluent to regulate the temperature of the combustion process. A booster increases the pressure of the gaseous exhaust gas before it is compressed into a compressed recirculation stream. A purge stream exits the compressed recycle stream and is directed to a CO2 separator configured to absorb CO2 from the purge stream using potassium carbonate solvent.
