FGD SCRUBBER MATERIAL Material Description. ORIGIN. The burning of pulverized coal in electric power plants produces sulfur dioxide (SO 2) gas 1990 Clean Air Act and its subsequent amendments mandated the reduction of power plant SO 2 emissions. The Best Demonstrated Available Technology (BDAT) for reducing SO 2 emissions is wet scrubber flue gas desulfurization (FGD) .

In a flue gas desulphurisation system (FGD), sulphur compounds are removed from the exhaust emissions of fossilfuelled power is done by means of an industrial process through the addition of absorbents. This can remove up to 95 % of the sulphur dioxide from the flue gas, since the current threshold value for SO 2 in the EU is 200 mg/Nm 3 (Nm 3 = normal cubic metre).
