flue gas desulfurization

Flue gas desulfurization is a technology that employs a sorbent, usually lime or limestone, to remove sulfur dioxide from the gases produced by burning fossil fuels before discharge to the atmosphere. Flue gas desulfurization is the current state-of-the art technology for major SO2 emitters, such as power plants.


A flue-gas desulfurization unit is also called a scrubber.
