PLANT FOR PREPARATION OF PETROLEUM ASSOCIATED GAS OR NATURAL GAS FOR TRANSPORTATION ALONG PIPELINE AND PRODUCTION OF LIQUID HYDROCARBONS FROM SAID GAS Russian patent published in 2006 - IPC F17D1/02 

FIELD: preparation and transportation of petroleum associated and natural gases.

SUBSTANCE: invention relates to preparation of gas for transportation along gas pipeline and separation of heavy fraction condensate from gas. Proposed plant for preparation of petroleum associated gas or natural gas for transportation along gas pipeline and obtaining of liquid hydrocarbons from gas intake line, device to increase and decrease pressure, gas flow line, liquid hydrocarbons extraction line, three-circuit heat exchanger, separator, expansion valve, two regulating valves and swirl pipe whose input is connected through pressure increasing and decreasing device from one side with inlet gas line through first regulating valve and through series-connected second regulating valve and first circuit of heat exchanger, and from other side, with output of expansion valve. Output of cold flow of swirl pipe is connected through second circuit of heat exchangers with gas flow line, output of hot flow of swirl pipe is connected through third circuit of heat exchanger with input of separator whose condensate output is connected with line to remove liquid hydrocarbons, and gas output, with input of expansion valve.

EFFECT: increased degree of separation of condensate of heavy fractions of hydrocarbons from petroleum associated gas or natural gas designed for transportation along gas pipeline.
