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...

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 sulphide content in SSC leads to its toxic property, obnoxious odor and hazardous nature. This will threaten health and safety of workers, and may pollute the environment. The SSC may not be discharged to wastewater treatment facilities untreated as the high sulphide content will cause corrosion in the pipes especially in aqueous condition. In fact, the Malaysia Department of Environment has limited the acceptable sulphide discharge in industrial effluent at 0.5 mg/L as stated in the Environmental Quality (Industrial Effluent) Regulation 2009.
