OXIDATION OF CONTAMINANTS IN REFINERY WASTE AND WASTEWATER USING PERMANGANATE
Abstract:Amines, phenols, and sulfur compounds are process water contaminants present in oil refinery wastewater. There are times when the amount of these contaminants, either due to volume, concentration, or both, causes a substantial increase in the loading to the wastewater treatment plant (WWTP). This increased loading carries with it costs for the WWTP (discharge permit violations) and potential consequences for the operation unit(s). Specifically, if this waste is drained to the sewer too quickly, these contaminants will result in an upset to the activated sludge plant resulting in violations to the facility's NPDES water discharge permit. This paper describes a treatment project that was developed to allow an increase in drain rate to the sewer (from caustic storage tanks containing high concentrations of phenol) without adverse affects at the WWTP. Because oxidation is one of the most effective technologies for destruction of phenol, oxidation with permanganate was selected and evaluated.
