Abstract

Procedure for the purification and recovery of used crankcase oil, characterized in that it comprises separating said oil with steam, to separate the volatile substances from it; deasphalting said separated oil with steam in a countercurrent solvent deasphalizer system; hydrogenate the deasphalt oil to separate impurities from it; and recover a lubricating oil of good color and viscosity.
