Sulfur Dioxide Scrubbers - Air Quality - Duke Energy

An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas.
