Recycling waste lube oils for profit (UOP Direct Contact Hydrogenation Process)
- UOP, Des Plaines, IL (USA)
An innovative new re-refining process has evolved from existing commercial petroleum refinery technology providing an economic means of treating and recycling potentially hazardous waste oils. Direct Contact Hydrogenation (DCH) eliminates the need for burdensome pretreatment steps such as dewatering, light ends removal and vacuum evaporation that require considerable volume of intermediate product storage capacity and present hazardous by-product disposal problems. By treating the entire waste oil in a heated hydrogen-rich atmosphere, the yield of recyclable high quality products is increased by up to 30% while at the same time eliminating the co-production of hazardous distillate fractions. The additional yield combined with a completely integrated continuous processing scheme results in an economic scenario that is competitive with the production of virgin derived lubricating oil products. The availability of this technology under license from UOP offers the industry an opportunity for increased profits from the recycle of lubricating oils.
