OXIDATION OF SODIUM SULFIDE IN INDUSTRIAL WASTEWATER AND SPENT CAUSTIC BY HYDROCHLORITE ION SOLUTION

Oxidation of sulfide ion found in Ras Lanuf Oil and Gas Co (RasCo) industrial wastewater and spent caustic to soluble sulphate ion by hypochlorite ion. The method is based on industrial wastewater and spent caustic treatment with free dichromate ion hypochlorite ion solution for a short period of time sufficient to oxidize sulfide ion to sulphate ion. The method is practical and prompt to oxidize sulfide ion to sulphate ion.
