Abstract

In the separation of waxes from oils by flotation at a temperature below the cloud point the feed contains cracked material and has a viscosity of not more than 20 centistokes at the separation temperature. Dewaxing is effected at 0-80 DEG F. using nitrogen, flue gas, hydrogen, gaseous hydrocarbons or air for the flotation in amounts of 0.1-10 vols. (S.T.P.) per volume of oil. The oil is cooled as described in Specification 1,022,430.
