FIELD: pipe line transportation. SUBSTANCE: proposed method includes extraction and transfer of oil refinery tar by obtaining oil-in-water dispersions from said tar; such dispersions contain at least 20 mass-% of water; dispersing agent is selected from salts of alkaline metals, ammonium and respective mixtures and salts of polymer sulfonates obtained due to condensation of naphthalenesulfonic acid and formaldehyde. Proposed method includes the following stages: (a) thinning of tar by heating it to temperature equal to its softening point; (b) mixing thinned tar with required amount of water and dispersing agent for forming oil-in-water dispersion and (c) extracting and mixing tar in form of oil-in-water dispersion obtained at stage (b). EFFECT: enhanced efficiency. 5 cl, 3 tbl
