Abstract: A method for capturing ammonia present in combustion flue gas subjected to carbon dioxide removal using a water wash unit included in a chilled ammonia process. The method includes combining a CO2 loaded liquid and a wash water liquid to form a CO2 enriched wash water liquid that is then brought into contact with the combustion flue gas.
