The processing of spent caustic products for BOD / COD reduction, odor control, and pH adjustment to allow the final stream to meet specifications for wastewater treating facilities. For the treatment of sulphidic caustic solutions, an effective wet oxidation process should eliminate sulphidic pollutants and produces a brine solution that can be disposed of without adverse environmental effects. The oxidation system selected is based on the type of used caustic solution being treated and the brine effluent specifications. Depending on the degree of oxidation needed to meet the refinery effluent specifications, the refinery may choose to install a partial oxidation process or a total oxidation system or deep neutralization system.
