A process for processing acid tars using membrane technology is proposed. Petroleum products are obtained as a result -lube oil, resin, solid fuel.In refining crude oil into a commercial product, in particular, in treatment of lube oils, waxes, and motor fuel, large-tonnage, environmentally hazardous (toxicity class 2) wastes -acid tars -are formed. These wastes are frequently discharged and stored in special ponds -open-air earthen tanks of man-made and natural origin.The acid tar reserves in CIS countries have reached 1-1.5 million tons according to different sources of information. There are also acid-tar ponds in other countries -Hungary, Brazil, Mexico, etc. Hundreds of thousands of tons of these wastes are concentrated in these ponds.It should be noted that the information on all sites of accumulation of large amounts of acid tars cannot be considered reliable. Companies, organizations, and other owners carrying storage ponds on the balance sheet are not interested in divulging them due to the recent strengthening of liability for environmental pollution.The situation is also similar for processing of acid tars in Ukraine.The proposed methods of utilizing acid tars (basically using expensive foreign units) are based on partial neutralization (with lime), homogenization, and conversion of toxic wastes to neutral wastes and on combustion of the bottom layer. These methods are suitable for utilization of acid tars of a certain kind. They are usually
