FIELD: methods of utilization of waste motor oil. ^ SUBSTANCE: the invention is dealt with utilization of waste and may be used in the field, where four-stroke engines are used. The method provides, that the waste motor oil is heated up to the temperature of 70-80 and fed to the apparatus of centrifugal clarification. In the apparatus of centrifugal clarification the waste oil is separated for an oil phase and a water-oil slime. The water-oil slime then is subjected to filtration. As a result of the filtration a separation of a water phase and an oil slime. The oil slime then may be used further at production of asphalt. The oil phase is exposed to clarification by the chemisorptive and adsorptive filtration. Then the clarified waste motor oil may be added to a fresh motor oil in amount of no more than 30 %. The method is pollution-free and cheap, and addition of the clarified waste motor oil in amount of no more than 30 % into a fresh motor oil allows to receive a mixture practically corresponding to the fresh oil. ^ EFFECT: the method is pollution-free and cheap. ^ 1 ex |
