Protective Materials For FGD Infrastructure
By Sauereisen
Flue gas desulfurization (FGD) is the technology used for removing sulfur dioxide (SO2) from the exhaust flue gases in power plants. Corrosion in FGD systems is an extremely important concern associated with the use of wet scrubbers. There are, however, two methods that minimize corrosion. The first method is to reheat the gases to above their dew point, and the second is to choose construction materials and design conditions that allow equipment to withstand the corrosive conditions.
