COAL-FIRED POWER PLANTS:SULFUR DIOXIDE REMOVAL .

Feb 14, 2016· Sorbent injection into a flue-gas stream is one of the cheapest methods of capturing sulfur but it is not the most efficient. The best established method of removing most of the sulfur from the flue gas of a power plant is with a flue-gas desulfurization (FGD) unit, also called a wet scrubber.
