METHOD OF TREATING GAS-CONDENSATE MIXTURE FOR TRANSPORTATION Russian patent published in 1999 - IPC

FIELD: oil and gas production. SUBSTANCE: invention aims at reducing amount of toxic aqueous solution of inhibitor accumulated at low-temperature separation plant and reducing losses of inhibitor and hydrocarbon concentrate. Method includes feeding formation product into first- step separator and removing liquid phase therefrom into first-step divider. A part of cooled first-step condensate is fed into gas stream before third-step separator. Liquid phase is withdrawn from third-step separator into second-step divider. Gas from third-step separator is successively transferred through second- and first-step heat exchangers to consumer. Liquid phase from second-step separator is combined with part of first-step hydrocarbon condensate and resultant mixture is fed into gas stream before third-step separator. EFFECT: reduced loss of inhibitor and improved environmental condition. 1 dwg, 1 tbl
