A brief review of the state of collection, disposal and processing of used oils shows the availability of their resource in the country and the main trends in the organization of qualified collection, disposal and processing according to the lubricating oil version. The relevant technologies are given for individual stages and in general for enterprises, the choice of which depends on the quality and characteristics of raw materials. The advantage of the technological scheme, including coagulation purification at the stage of raw material preparation and vacuum distillation with the selection of distillate fractions and the residue, followed by additional purification of the residue, is shown. The use of this technology makes it possible to increase the yield and quality of the target product, which is practically impossible for the raw materials currently available in the Russian Federation using other technologies.
