VSEP recycles used motor oil at 90°C providing a filtrate suitable for use as marine grade diesel fuel or lube oil feedstock
A unique membrane filtration system was installed in July 2001 at a major waste oil re-refining operation in Portland, Oregan. The system manufactured by New Logic Research, Inc. of Emeryville, California near San Francisco, is being used to process used crankcase waste oil and produce filtrate that can be sold as a higher value bunker oil. The VSEP, (Vibratory Shear Enhanced Process), system uses a Microfiltration membrane module with special construction for service with high temperature solvents and waste oils and is able to process up to 80% of the dewatered waste oil. The use of high temperature polymeric membranes has many significant advantages over the conventional methods of oil rerefing and also over expensive ceramic and inorganic filter media. New Logic's use of Polymeric membranes in it's VSEP Filter Pack is ground breaking and has stirred the interest of oil recycling companies around the world.
