A survey of flue-gas desulfurization processes covers the throwaway lime/limestone process, the most common method, with almost 90 3< efficiency; the unreliability of such wet scrubbing systems due to scaling, plugging, corrosion, and erosion; the major control loops of a scrubber system; the double alkali scrubbing method which uses sodium hydroxide or sulfite for scrubbing and calcium oxide or hydroxide for regeneration; current recovery processes which yield salable by-products and which include the magnesium oxide scrubber and the Wellman-Lord process, which reduces SO/sub 2/ to elemental sulfur; the dry scrubber/absorber process which, as yet, is only useful for low-sulfur coal application and forms a dry product; and the Clean Air Act Amendments emission standards which may cost $88 billion by 1995.
