Method for desulfurization of flue gases (Patent) OSTI.GOV

May 21, 1991  Flue gas desulfurization (FGD) processes have been widely used since the early 1970's for control of sulfur dioxide emissions from coal-fired power plants. First generation FGD systems employ ''wet processes'' whereby the flue gas is contacted with a solution or slurry of an alkali reagent. Most of these installations use either lime or limestone.

FLUE GAS DESULFURIZATION - Emerson Electric

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.

Flue-gas desulfurization - Wikipedia

Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the S
