user.eng.umd.eduNatural Gas Desulfurization The natural gas is delivered as dry gas containing a maximum of 40 ppm by weight of sulfur, which is a poison for the reformer catalyst. The desulfurization unit reduces the sulfur content to about 5 ppm by hydrogenating it to hydrocarbons and hydrogen sulfide and then absorbing
FLUE GAS DESULFURIZATION - Emerson Electric
www.emerson.comWhat 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.
