What Gas Does Desulfurization Remove?

Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from flue gases produced from industrial combustion at petrol refineries, chemical manufacturing industries, mineral ore processing plants, and power stations to name a few.

Which gas is used for desulfurization?

Desulfurization is the process of using hydrogen gas to reduce the sulfur content in hydrocarbons thus reducing the emissions of sulfur oxides which are responsible for acid rain.

How effective is flue gas desulfurization?

For a typical coal-fired power plant, FGD systems will remove ~95% of the SO₂ in the flue gases. FGD predominantly employs two methods of filtering the emissions (dry or wet scrubbing) for coal-burning plants to be in compliance with regulations mandated by the EPA's Effluent Limitation Guidelines (ELG).
