Sulfur in coal cannot be destroyed; it can only be converted to one form or another. The technology of Flue Gas Desulfurization (or FGD) is therefore one of conversion, but the technology is generally split according to the type of end product generated, rather than by the exact chemical route used. With this viewpoint, the two broad classes of FGD are: Non-regenerable (or throwaway) Processes: These produce sulfate salts which are worthless and must be discarded. Regenerable Processes: These produce sulfur or sulfuric acid which have a potential market value. The throwaway type of FGD systems received the greatest development push back in the late 1960's, and they have become the most widely applied type today. Therefore, the current technology can best be illustrated by examining some of the components in a throwaway system.
