Abstract
A system and method are described in which sulfur-containing flue gases are contacted with a solution containing excess calcium or magnesium bicarbonate. The sulfur oxides are reacted with the bicarbonate producing soluble bisulfites. This solution is then oxidized for pH control to produce calcium or magnesium sulfate and sulfuric acid. Dolomite or limestone or similar additives are then introduced to precipitate sulfates and to regenerate the bicarbonate solution for recycle to the scrubber.
