The tightening of environmental regulations world-wide is causing the petroleum refining industry to rethink its processing options. New approaches are being implemented both for production of cleaner petroleum products, and for the generation and handling of waste effluents. A large portion of refinery effluent is spent caustic. Because spent caustic is a hazardous waste, its disposal is difficult and expensive for the refiner. The UOP Merox process is the refining industry standard for mercaptan control in gasoline and kerosine. However, it can be a generator of spent caustic waste. During the 30 year commercial lifetime of this process, UOP has made step-wise improvements that have led to the complete elimination of spent caustic effluent. Changes made in the catalyst system and process conditions led to a new process whose characteristics are in line with the needs of an environmentally aware refining industry.
