What is Foots Oil?
at Monday, August 9, 2010
For preparing lubricant base stocks, crudes are treated by subjecting
to atmospheric distillation
followed by vacuum distillation from which the lube base stock boiling range cut is taken,
solvent extracted, usually with furfural, and then solvent dewaxed, usually with methylethyl ketone or the like to produce a product which, upon filtration, is separated into a lubricant base stock and a wax.
In order to further purify the wax fraction into a product of extremely high value, it is subjected to conventional deoiling from which a rather hard waxy product is recovered and from which a mixture of oil and soft wax by-product is also produced. This mixture of oil and soft wax is generally referred to as Foots oils.
