ABSTRACT:
A power generation system includes at least one turbine system. The turbine system includes a compressor section comprising at least one stage, configured to supply a compressed oxidant and a combustion chamber configured to combust the compressed oxidant and a fuel stream comprising carbon-based fuels and to generate a hot flue gas. The turbine system further includes an expander section having an inlet for receiving the hot flue gas comprising at least two stages. The two stages include a high-pressure expander configured to generate an expanded exhaust gas rich in CO2. The high-pressure expander fluidly coupled to a low-pressure expander configured to generate a final exhaust and electrical energy. A CO2separation system is fluidly coupled to the high-pressure expander for receiving the expanded exhaust gas from the high-pressure expander and providing a CO2lean gas that is then fed to the low-pressure expander.
