METHOD OF PREPARATION FOR TRANSPORTATION OF NATURAL GAS Russian patent published in 2016 - IPC F17D1/00 

FIELD: gas industry.

SUBSTANCE: invention relates to production of natural gas, in particular its preparation for transportation, as well as operation of gas collector pipelines and heat exchange unit for reducing gas temperature after compression. Method of preparation for transportation of natural gas consists in delivery of gas from well to booster compressor station via gas line, cleaning, compression and cooling of gas in heat exchanger using water-methanol solution (WMS), which after heat exchanger in a heated condition is supplied for cooling gas cavity through pipeline of smaller diameter laid inside gas pipeline, and WMS cooled in gas pipeline is returned to heat exchanger along external pipeline; wherein depending on ambient temperature initially WMS can be directed towards well after heat exchanger in external pipeline, and from well to heat exchanger - along pipeline laid inside gas line.

EFFECT: technical task of invention is providing simultaneous efficient and trouble-free operation of two interconnected process systems: collection of natural gas and its cooling in heat exchange unit after compression.
