METHOD FOR PREPARATION OF HYDROCARBON GAS AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F25J3/00 

FIELD: oil and gas industry.

SUBSTANCE: method includes separation of gas with branches of separated hydrocarbon condensate and water, adsorption drying and stripping of gas, withdrawal of prepared gas, regeneration of adsorbent, stabilisation of hydrocarbon condensate separated during gas separation and obtained at cooling and separation of gas after regeneration of adsorbent, with discharge of stable condensate and stabilisation gases, released stabilisation gases are directed to own needs or to compression with subsequent feed to inital gas flow, or to prepared gas flow, and spent regeneration gas is cooled by throttling followed by rectification to further produce a stable condensate, at that, stabilisation of hydrocarbon condensate separated during gas separation and obtained with cooling and separation of gas after regeneration of adsorbent, exhaust gas subjected to throttling is used for cooling.

EFFECT: reduction of heavy hydrocarbon losses.
