FIELD: process engineering.
SUBSTANCE: invention relates to oil-and-gas industry. Proposed plant comprises refrigerator, pipeline connected with tank vapor zone and refrigerator, pump, shutoff valves and accessories and connection pipelines. Note here that refrigerator 1 is composed of vapor-air mix condenser communicated with refrigerator 2 and comprises cylindrical body 6 with outer heat insulation. Said body accommodates coaxial one or several hollows baffles composed of sleeves 7. Coolant pipeline 8 is coiled outer surface of every said sleeve at staggered pitch to make vapor-air flow swirl to create centrifugal forces and optimum contact with cold surface. Ends of pipeline 8 are rigidly fixed at bottom of said body having coolant inlet and outlet pipes 9, 10 connected with refrigerator 2. Vapor-air mix condensate drain union 11 is arranged at body bottom center and connected via pipe 12 with condensate collection tank 3 equipped with water header 4 with drain valve 5. Pipeline 19 with valve 20 is connected to said tank 3 to communicate the latter with pump 21 of tank 17. Body top is tightly closed by cover 13 fitted with vapor-air mix feed union 14 to feed said mix from tank 17 and union 15 to discharge clean air to drain tank. Note here that refrigerator housing 6 accommodates pressure and temperature gages connected with instrumentation and refrigerator control unit 22.
EFFECT: higher quality of oil products, better ecology.
