FIELD: oil and gas industry.
SUBSTANCE: method is provided, comprising mixing the gas with the separation gas, compressing the obtained mixture, cooling the liquid hydrocarbons under dephlegmation with external coolant to obtain the compressed gas and condensate, which is throttled to obtain the separation gas and the stabilized condensate. To implement the method, the device is proposed, consisting of a compressor equipped with the gas injection line connected to the separator with the gas supply line of separation, and connected by the supply line of the liquid hydrocarbons with a dephlegmator equipped with a compressed gas output line and the output line of the condensate, on which the throttling device is mounted.
EFFECT: increase in volumetric output of compressed gas, reduction of pressure of saturated vapour of the condensate and reduction of losses of heavy components with the compressed gas.
