Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide () from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes. ==Methods== As stringent environmental regulations regarding SO2 emissions have been enacted in many countries, is now being removed from flue gases by a variety of methods. Below are common methods used: *Wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime, or seawater to scrub gases; *Spray-dry scrubbing using similar sorbent slurries; *Wet sulfuric acid process recovering sulfur in the form of commercial quality sulfuric acid; *SNOX Flue gas desulfurization removes sulfur dioxide, nitrogen oxides and particulates from flue gases; *Dry sorbent injection systems. For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 95 percent or more of the in the flue gases. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flue-gas desulfurization」の詳細全文を読む スポンサード リンク
