FIELD: environmental control, particularly, protection of water basin from pollution with oil products, fats and oils; applicable at objects of oil production, processing and pumping over, and also in utilization of oil sediments in oil tanks, etc. SUBSTANCE: method consists in separation of mixture of liquids into fractions by forward motion of endless pulling and accumulating member through separation vessel. Fractions are separated due to provision of elastoplastic deformation of member with contact pressure in tunnel chamber of variable section. Device has conveyer with pulling member, tunnel chamber with holes in its walls for fraction draining. EFFECT: extended functional potentialities; higher efficiency of the method. 7 cl, 5 dwg
