May 18, 2019· Flue gas desulfurization is required to reduce the amount of sulfur dioxide getting into the air. It is a large factor in the formation of acid rain. A device called a scrubber is used to remove sulfur from flue gas. It works by combining the sulfur with lime or limestone to create a compound or slurry.
