Flue Gas Desulfurization (FGD) is a collection of technologies utilized to remove sulfur dioxide from exhaust flue gases in sulfur oxide-emitting processes, such as coal-fired boilers, paper and pulp facilities, diesel generators, oil-fired boilers, and waste incinerators. The sulfur dioxide (SO2) produced by burning coal, oil, natural gas, or wood is removed from the flue gas using absorbents.

Outdoor air quality is a vital aspect to be maintained to safeguard humans from the hazardous health effects caused due to toxic pollutants. Hence, FGD systems control and curtail the emission of SO2 and other gaseous pollutants. By purifying gases created during numerous industrial operations, including the production of cement, glass, paper, iron, steel, and copper, it aids in reducing air pollution. It also helps to prevent acid rain, which is brought on by an airborne concentration of sulfur dioxide (SO2) and nitrogen oxides (NOX) that is too high.
