ABSTRACT:
A method and system for controlling emissions with ammonia recovery and fly ash beneficiation in accordance with the present invention includes introducing ammonia to react with at least a portion of sulfur trioxides in an exhaust emission and result in at least one or more ammoniated compounds. At a least a portion of fly ash particles and the ammoniated compounds in the exhaust emission are precipitated and at least the precipitated fly ash particles are beneficiated. At least a portion of the beneficiated fly ash particles which are heated are mixed with the precipitated ammoniated compounds to recover at least a portion of the ammonia. The recovered ammonia is reused in introducing ammonia to react with at least a portion of sulfur trioxides.
