Abstract
A power plant includes a gas turbine unit adapted to feed flue gases into a boiler of a steam turbine unit, to be then diverted into a recirculated flow and discharged flow. The recirculated flow is mixed with fresh air forming a mixture that is fed into a gas turbine unit compressor. The discharged flow is fed into a CO2 capture unit that is an amine based or chilled ammonia based CO2 capture unit. A cooler for the flue gases can be configured as a shower cooler located upstream of the CO2 capture unit. The plant can also include a washing unit to neutralize ammonia drawn by the flue gases that can be fed with nitric acid gathered at the cooler.
