What is Flue-Gas Desulfurization (FGD)? Definition from

Flue-gas desulfurization (FGD) is the removal process of sulfur dioxide (SO 2) from flue gas emissions, often chemically. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.

The by-product from the combination process is a completely dry powder. As a result, the need for waste water treatment for the wet scrubber purge stream is eliminated. In addition, the combination system allows low cost limestone to be used as a sorbent while providing an easy to handle, free flowing solid by-product.

Flue Gas Scrubber for SO2 Absorption By MET

In sodium scrubbing, a solution of sodium hydroxide, sodium carbonate or sodium bicarbonate absorbs the SO 2 from the flue gas. The SO 2 reacts to form sodium sulfite and sodium bisulfite which are dissolved in solution. Part of all of the sulfites can be oxidized to form sodium sulfate.
