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.
