Preliminary study of sulphide removal using ion exchange resin

The paper presents the investigation of sulphide removal via ion exchange resin. Sulphidic spent caustic (SSC) is a dark brown to black effluent generated from petrochemical and oil refinery industries. Typically, SSC has a pH of 13-14, and sulphide concentration of 0.5-4.0wt%. The large amount of s...
