Flue-gas desulfurization - Wikipedia

Flue gas desulfurization scrubbers have been applied to combustion units firing coal and oil that range in size from 5 MW to 1500 MW. Scottish Power are spending £400 million installing FGD at Longannet power station, which has a capacity of over 2 GW. Dry scrubbers and spray scrubbers have generally been applied to units smaller than 300 MW.

Flue-Gas Desulfurization (FGD) Working | Thermal Power Plant

Apr 11, 2021 · Flue-gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. 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.

Performance of Dry Flue Gas Desulfurization on a Petroleum

The flue gas clean-up system is designed to process 205,000 acfm leaving the waste heat boiler at approximately 405°F. The system removes a minimum of 90% of the sulfur dioxide in the untreated gas (1100 ppm), and reduces the solid par-ticulate concentration to less than .005 gr/acf. Calcium hy-droxide slurry is the absorbing medium for SO2 control.

FLUE GAS DESULFURIZATION - Emerson Electric

Exhaust flue gas is drawn from the boiler and forced into an absorber tower by a booster fan. Once inside the absorber tower, the gas flows upwards through a dense shower of lime or limestone slurry. The slurry absorbs the Sulfur Dioxide (SO2) in the flue gas. The absorption process …
