FIELD: oil refining. SUBSTANCE: residues of crude oil refining are mixed with dimethyl carbonate at temperature equal to, or exceeding that of formation of homogeneous solution with its subsequent cooling down to temperature below that of formation of homogeneous solution. Mixture is separated in settler into cleaned light liquid phase containing asphaltenes and extracted medium liquid phase which in amount of 10-90 mas. % is recirculated for stage of mixing with dimethyl carbonate, and remaining part is directed for solvent regeneration. EFFECT: higher efficiency. 8 cl, 1 dwg
