FIELD: oil and gas industry.
SUBSTANCE: crude gas 1 is separated at the first stage, obtaining the gas 3 of moisture 4 and hydrocarbon 5 condensates, the latest is reduced by means of the device 6 and separated with obtaining the gas 8 and the residual part 9. The gas of the first stage 3 is reduced by means of the device 10 and in the mixture with the deethanizated gas 8 at the second stage is cooled down upon the conditions of partial condensation in the fractional column 11 with obtaining the condensed fluid 12 and the gas 13, which is reduced by means of the device 14, heated, combined with the deethanizated gas 15 and extracted as the sales gas 16. The condensed fluid of the second stage 12 is reduced by means of the device 17 and debutanized jointly with the reduced by the device 18 residual part of the deethanizing 9 with obtaining the sales condensate 20 and the gas of debutanization 15.
EFFECT: increasing of the sales gas flow and improving the quality of the condensed fluid.
