Flue-gas desulfurization is an absorption process by which sulfur dioxide in flue gas from fossil-fuel power plants and from the emissions of other sulfur-oxide-emitting processes can be controlled. SO 2 is removed from flue gases by a variety of methods, common ones being: Wet scrubbing using a slurry of alkaline sorbent, usually limestone ...
