Abstract

Brine purification process of GHCL did not meet the specification of electrolyzer in the context of excess
hydroxide ion (OH-). The electrolyzer, anolyte tank and dechlorination tower tank faced serious corrosion.
This paper describes an innovative method adopted to meet the electrolyzer's specification of excess OH-.
This method consists of an innovative HCl dosing system added to purified brine tank. After adopting this
method corrosion of electrolyzer, anolyte tank and dechlorination tower tank has been decreased in a
noticeable rate. Also some chemical dosings have been reduced.
