METHOD FOR PREPARING GAS-CONDENSATE MIXTURE TO TRANSPORTATION Russian patent published in 1997 - IPC

FIELD: oil and gas production industry. SUBSTANCE: this method prevents falling of paraffined hydrocarbons into solid residue on surfaces of heat exchanging equipment, increases its heat-transfer coefficient, reduces separation temperature, and enhances proportion of heavy hydrocarbons coming into liquid phase. According to method, branched from first-stage separator is liquid phase for further treatment. Separated gas is delivered through heat exchanger to second-stage separator. Liquid phase is branched from second-stage separator for further treatment. Gas separated at second stage is cooled in second-stage heat exchanger. Then gas is throttled and delivered to third-stage separator. Liquid phase is removed from it. Gas separated at third stage is supplied to consumer. Liquid phase branched out after third-stage separator is divided into two portions. One portion is delivered by pump into pipeline between first-stage separator and first-stage heat exchanger in such proportion that paraffin-creating components do not fall into solid residue in equipment. Other part of liquid phase is branched out for further treatment. EFFECT: high efficiency. 3 tbl, 1 dwg
