Abstract:
1. A method for CO 2 separation from a combined-cycle power plant, the method comprising: splitting a gas flow, expanded in a gas turbine, after a high-pressure turbine and upstream of a low-pressure turbine; expanding further a first partial mass flow of the split gas flow in the low pressure turbine and dissipating waste heat therefrom in a usable form; mixing induction air with the first partial mass flow after the first partial mass flow is expanded in the low pressure turbine; recirculating the first partial mass flow and the induction air mixed therewith into an inlet of a compressor of the gas turbine; diverting a second partial mass flow of the split gas flow, as an extraction flow; cooling the diverted second partial mass flow; separating CO emitting the CO
