Abstract
A system and method is disclosed for recovering reagents that are used in removing contaminants from a flue gas stream. The system and method includes contacting the flue gas stream with reagents such as ammonia and sulfuric acid to create an ammonium sulfate stream. The ammoniated sulfate stream is forwarded to an electrodialysis unit wherein the reagents are regenerated and recirculated back to the system.
