The paper is an overview of utility flue gas desulfurization (FGD) technology and costs. The two commercially offered throwaway and salable product systems that are considered to be the most important for near-term (through 1990) SO2 control are: throwaway product systems--lime and limestone scrubbing (both sludge and gypsum variations) and dual (double) alkali; and salable product systems--magnesium oxide scrubbing and Wellman-Lord (sodium sulfite scrubbing). Other potentially important systems which are close to commercialization include dry scrubbing, seawater scrubbing, carbon adsorption, and copper oxide adsorption.
