FIELD: oil industry.
SUBSTANCE: device comprises five towers separated at the middle. The halves of the towers are connected with compressors. The top halves of towers are provided with condensers, and the bottom halves are provided with heaters. The discharging pipes of the condensers are connected with the bottom halves of the next tower. The condensates are supplied from the dummy plates to the top halves of the next towers, and condensate of the fifth tower (gas oil) is finished product. The number of discharging pipes is equal to the number of towers. The temperature of initial oil is equal to 20-23°C. The temperature of the oil in the condensers of two first towers is equal to 35°C.
EFFECT: enhanced efficiency.
