Abstract:
1. A method of power generation comprising: introducing a fuel, O combusting the fuel to provide a combustion product stream comprising CO expanding the combustion product stream across a turbine to generate power, the turbine having an inlet for receiving the combustion product stream and an outlet for release of a turbine discharge stream comprising CO withdrawing heat from the turbine discharge stream by passing the turbine discharge stream through a primary heat exchange unit to provide a cooled turbine discharge stream; removing from the cooled turbine discharge stream one or more secondary components that are present in the cooled turbine discharge stream in addition to CO compressing the purified, cooled turbine discharge stream with a first compressor to a pressure above the CO cooling the supercritical CO passing the supercritical, high density CO passing the supercritical, high density, high pressure CO supplying an additional quantity of heat from a source other than withdrawn heat from the turbine discharge stream to all or a portion of the supercritical, high density, high pressure CO recycling the heated, supercritical, high density CO wherein the temperature of the heated, supercritical, high density CO
