FIELD: oil and gas production industry. SUBSTANCE: according to method, product from bed is delivered to first-stage separator, then liquid phase is taken out for further processing. Delivery of gas separated at first stage is effected through heat exchanger of first stage of cooling to separator of second stage. From second-stage separator, liquid phase is branched out for further processing. Gas separated at second stage is delivered through heat exchanger of second-stage cooling and expansion device to separator of third stage, and liquid phase is taken out from this separator. Gas separated at third stage is delivered through heat exchanger of second-stage cooling directly to consumer. Branched-out liquid phase after third-stage separator is divided into two parts. One part is delivered by pump into middle part of first-stage separator in such proportion that paraffins are not precipitated into solid residue in device. Other part of liquid phase is branched out for further processing. Application of aforesaid method prevents precipitation of paraffin hydrocarbons into solid residue on surfaces of heat-exchanging equipment, improves efficiency of its operation, reduces temperature of separation, and increases yield of heavy hydrocarbons going into liquid phase. EFFECT: higher efficiency. 1 dwgt |
