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.

The power plant of claim 1, wherein an oxidizer is provided to the flue gases upstream of and/or within the cooler. 3. The power plant of claim 1, wherein the cooler is provided downstream of the boiler and upstream of a diverter that diverts the flue gases into the recirculated flow and the discharged flow. 4. The power plant of claim 1, wherein the boiler is a reheat boiler. 5. The power plant of claim 1, wherein the cooler is upstream of a diverter that diverts the flue gases into the recirculated flow and the discharged flow. 6. The power plant of claim 5, comprising: an oxidizer that is positioned between the boiler and the cooler. 7. The power plant of claim 5, comprising a liquid oxidizer positioned at a top of the cooler. 8. The power plant of claim 1, wherein the cooler is configured such that flue gases rise from a bottom of a casing of the cooler and a cooling liquid falls from a top of the casing of the cooler. 9. A method for operating a power plant comprising a gas turbine unit adapted to feed flue gases into a boiler of a steam turbine unit, the method comprising: diverting the flue gases into a recirculated flow and a discharged flow,mixing the recirculated flow with fresh air forming a mixture,feeding the mixture into a gas turbine unit compressor,feeding the discharged flow into a CO2 capture unit,operating the CO2 capture unit as an amine based or chilled ammonia based CO2 capture unit, wherein the CO2 capture unit is a chilled ammonia based capture plant comprising a washing unit to neutralize ammonia drawn by the flue gases,cooling the flue gases in a cooler, the cooler being a shower cooler located upstream of the CO2 capture unit, andfeeding the washing unit with nitric acid gathered at the cooler. 10. The method of claim 9, wherein the cooler is upstream of a diverter that diverts the flue gases into the recirculated flow and the discharged flow. 11. The method of claim 9, comprising: providing an oxidizer between the boiler and the cooler. 12. The method of claim 9, comprising: providing a liquid oxidizer positioned at a top of the cooler. 13. The method of claim 9, wherein the cooler is configured such that flue gases rise from a bottom of a casing of the cooler and a cooling liquid falls from a top of the casing of the cooler. 14. The method of claim 9, further comprising providing an oxidizer to the flue gases upstream of and/or within the cooler.
