FIELD: oil and gas industry.SUBSTANCE: method for deethanisation of unstable gas condensate (UGC) includes UGC division into two flows. The first flow is delivered to the first three-phase divider, wherein water-methanol solution and a part of deethanisation gas are separated from it. The second flow is heated in the heat exchanger and delivered to the second three-phase divider in order to separate water-methanol solution with mechanical impurities and blow off deethanisation gas. From the second three-phase divider UGC comes to the heat exchanger of reboiler type, whereat it is heated up by deethanised gas condensate up to the required temperature, degassed additionally and delivered as feed stock to deethanisation column. Gas outputs of three-phase dividers and deethanisation column are connected to the line of deethanisation gas discharge.EFFECT: reduced content of methane and ethane in UGC supplied to deethanisation column thus excluding disturbances in operation of the gas condensate deethanisation unit.5 cl, 1 dwg |
