Фазовое состояние газопроводной системы в промысловых условиях подготовки газа к транспорту

Abstract

Results of two liquid phase equilibrium study in polypropylene glycol – hydrocarbon condensate – surfactant system are presented. To develop highly effective processes of gas field treatment and transportation, need of experimental data on phase equilibrium in liquid systems containing hydrocarbon condensate, methanol, surfactant and high salinity formation waters, is evident. Phase equilibrium of hydrocarbon condensate methanol – water in field conditions of gas treatment depends on the quantity of liberated in this conditions liquid hydrocarbon phase, its group composition, methanol and surfactant concentration in water phase and salt composition of the latter. According to obtained results phase diagrams of polypropylene glycol – condensate – NaCl aqueous solution and polypropylene glycol – surfactant – hydrocarbon condensate system state are constructed.
