PLANT FOR PREPARATION OF HYDROCARBON GAS FOR TRANSPORTATION Russian patent published in 1999 - IPC

FIELD: plants for preparation of oil and natural gases for transportation to pipe line for processing. SUBSTANCE: plant includes compressor with low-pressure and high-pressure stages, interstage gas cooler mounted after low-pressure stage, separator for separation of condensate and water provided with liquid inlet branch pipe and condensate and water outlet branch pipes, separator for separation of gas from condensate and water provided with gas inlet branch pipe and gas and liquid outlet branch pipes (last branch pipe is connected with inlet branch pipe of condensate and water separator), water replenishing unit, terminal gas cooler mounted after high-pressure stage, separator for separation of gas from liquid provided with gas inlet branch pipe and gas, liquid and condensate outlet branch pipes. All these components are interconnected by means of pipe lines. Water outlet branch pipe of condensate and water separator is connected, via pump and filter, with inlet of inter-stage gas cooler; besides that, condensate and water separator is additionally provided with water inlet branch pipe connected with water replenishing unit and gas drainage water outlet branch pipes. liquid outlet branch of separator used for separation of gas from liquid is connected with liquid inlet branch pipe of condensate and water separator. Gas outlet branch pipe of condensate and water separator is connected with pipe line delivering the gas to low-pressure stage of compressor. EFFECT: enhanced reliability; reduced expenses. 3 cl, 1 dwg
