Abstract:
1. A method for operating a power plant including a CO2 process, the method comprising the steps of: compressing a working fluid into a circulation gas, a first secondary stream and a second secondary stream; heating the circulation gas at a constant pressure, heating the circulation gas at a constant volume, or both; expanding the circulation gas at a constant entropy; discharging heat from the circulation gas at a constant pressure, discharging heat from the circulation gas at a constant volume, or both; introducing the first secondary stream to an input side of a turbine; and regulating the degree of charging of the process at the input side of the turbine by controlling discharge of the second secondary stream to extract CO2; and the CO2 process comprising internal combustion of a fuel and an oxidant necessary for oxidation.
