The present disclosure relates to a system for removing a pollutant from a power generation cycle that utilizes a high pressure circulating fluid. The system includes a first direct contact cooling tower configured to cool the high pressure circulating fluid and condense a fluid stream that removes SO2 from the circulating fluid. A first recirculating pump fluidly communicates with the first direct contact cooling tower. The first tower includes an outlet configured to circulate a cooled CO2 product stream, and a second direct contact cooling tower is configured to receive at least a portion of the cooled CO2 product stream from the outlet. The second direct contact cooling tower is configured to cool the CO2 product stream and condense a fluid stream that removes NOx from the CO2 product stream. A second recirculating pump fluidly communicates with the second tower. An associated method is provided.
