摘要
The design of dechlorination units using sulfur dioxide as a reducing agent for once-through power plant cooling streams is considered. The average concentration of hypochloric ions is determined downstream from the point of injection of sulfurous acid as a function of the number of injection points and the initial sulfurous acid concentration. The results can be used for the design of sulfurous acid injection units required to reduce the hypochlorite ion concentration to a special level. A sample design calculation is presented for a typical power plant cooling stream.; The design of dechlorination units using sulfur dioxide as a reducing agent for once-through power plant cooling streams is considered.
