Flue Gas Desulfurization

Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. The process involves the wet scrubbing process that injects a lime or limestone reagent into the flue gas path to capture SO 2 as CaSO 3, which is then converted to CaSO 4 through forced air ...

FLUE GAS DESULFURIZATION

Exhaust flue gas is drawn from the boiler and forced into an absorber tower by a booster fan. Once inside the absorber tower, the gas flows upwards through a dense shower of lime or limestone slurry. The slurry absorbs the Sulfur Dioxide (SO2) in the flue gas. The absorption process converts the lime/limestone into Calcium Sulfite.
