597608 Disclosed is a method for removing elemental mercury from flue gas in wet scrubber comprising the steps of: providing a wet scrubber having a scrubber slurry; providing a flue gas comprising a sulfur dioxide (SO2), a oxidized mercury, and an elemental mercury; enabling the flue gas to pass through the scrubber; introducing a mercury oxidizer into the scrubber slurry, and oxidizing the elemental mercury with the mercury oxidizer at a gas-liquid interface of the flue gas and the scrubber slurry within the wet scrubber; and introducing a promoter into the scrubber slurry, wherein the promoter acts as an oxidizing agent for sulfite oxidation but not for elemental mercury oxidation. |
