FIELD: oil and gas production. ^ SUBSTANCE: invention refers to loading/unloading equipment intended for unloading of high-viscosity oil products in low temperature conditions. Device for emptying tank vessel (1) filled with fluid oil products and with loading/unloading opening (6) located on upper side includes downtake pipe (7) installed in the above opening, which has transport pipe (8) discharging oil product from tank vessel filling level area and transport pipe (9) located concentrically to it and supplying oil product to tank vessel filling level area. Both pipes ends are opened to internal space of tank vessel. To discharge transport pipe (8) there connected is pipeline (10) connected to inlet (12) of tank (13) of preliminary heating, which is filled with oil product, to the outlet of which there connected is supply line (17) connected to supply transport pipe (9). From discharge line (11) there branched is transport line (19) connected to return line (20) for oil product, which is connected to accumulator tank. Bypass line (24) with a valve is provided between supply line (17) and discharge line (11). ^ EFFECT: invention increases unloading and heating efficiency and provides compactness. ^ 7 cl, 3 dwg |
