ABSTRACT:
Power plants and process for lowering CO2emissions generally includes extracting a portion of the recirculated CO2-rich flue gas mid-way through the compression pathway of a gas turbine and removing the CO2in a separation unit. The remaining portion of the CO2rich flue gas (i.e., the portion of the recirculated flue gas that was not fed to the separation unit) is mixed with fresh air coming from an additional compressor-expander and then fed back to the compression pathway. As a result, flue gas recirculation increases the CO2concentration within the working fluid, leading to an additional increase in CO2partial pressure. As the concentration and partial pressure of CO2is increased, a lower energy penalty is observed to remove the CO2. Moreover, a reduced volume is fed to the CO2separation unit during operation. Consequently, the size of the separation equipment can be reduced as well as the energy required for the separation process.
