Abstract
Research has been conducted in this country and abroad for nearly 50 years to develop technology for control of sulfur dioxide emissions from coal-burning powerplants. This paper describes five wet- scrubbing systems that have received the most attention for commercial application. The processes are (1) wet limestone or lime scrubbing, (2) double alkali scrubbing, (3) magnesium oxide scrubbing, (4) catalytic oxidation, and (5) sodium-base scrubbing. The first two processes are nonregenerable and produce a throwaway sludge. In the remaining three processes, the sulfur dioxide absorbent is regenerated, and marketable sulfuric acid or elemental sulfur is produced.
