ABSTRACT:
A method and system for reducing an amount of ammonia in a flue gas stream. The system100includes: a wash vessel180for receiving an ammonia-containing flue gas stream170, the wash vessel180including a first absorption stage181aand a second absorption stage181b, each of the first absorption stage181aand the second absorption stage181bhaving a mass transfer device184; and a liquid187introduced to the wash vessel180, the liquid187for absorbing ammonia from the ammonia-containing flue gas stream170thereby forming an ammonia-rich liquid192and a reduced ammonia containing flue gas stream190exiting the wash vessel180.
