PROCESS FOR PROMOTING MERCURY RETENTION IN WET FLUE GAS DESULFURIZATION SYSTEMS

摘要

A system and method is proposed for removing mercury from a process gas stream containing mercury. The proposed invention provides for contacting an aqueous desulphurization liquor with a flue gas stream to capture mercury that may be contained in the flue gas stream. A promoter is mixed with the liquor to prevent oxidized mercury in the liquor from reducing into elemental mercury.
