ABSTRACT:
Oxidizable impurities, particularly hydrogen sulfide and ammonia, are removed from sodium chloride brines used for the electrolytic production of chlorine and caustic soda by oxidizing such impurities with hypochlorite at pH values at which the brines are commonly treated with sodium hydroxide and sodium carbonate to remove calcium and magnesium ions. The hypochlorite oxidation can be accomplished by adding to the brine the waste liquor from a scrubber in which a gas stream containing chlorine is scrubbed with a sodium hydroxide solution, which can be cell liquor. The gas stream so scrubbed can be the tail gases from the liquefaction of the chlorine produced by electrolysis of the brine.
