Abstract

Scrubber is used for scrubbing and removing corrosive gases from the flue gases, HCl generated by burning chlorine contg. cpds. The gaseous medium is blown through floors of the scrubbing column and acid solution is formed due to water spray. This soln. is drawn off, stored and recirculated.
