PROCESS OF PREPARATION OF GAS FOR CONVEYING Russian patent published in 2003 - IPC

FIELD: gas production, extraction of gas and its preparation for transportation. SUBSTANCE: process includes extraction of high-pressure gas-condensate mixture from well, preliminary cleaning, heat exchange and cooling of gas, low-temperature separation, drainage of hydrocarbon condensate for further separation and conveying of dried gas to user. Gas is cooled by its separation with the help of vortex tube into cold and hot gas flows and hydrocarbon condensate. Cold gas flow is directed for low- temperature separation. Hot gas flow is directed for mixing with main flow of dried gas conveyed to user. Hydrocarbon condensate is sorted out for subsequent separation. EFFECT: decreased energy and material consumption for preparation of gas, enhanced efficiency of technological process. 1 dwg
