PRODUCTION OF TREATED HYDROCARBONS GAS FROM GAS FLOW CONTAINING HYDROCARBONS AND ACID IMPURITIES |
摘要 |
FIELD: oil and gas industry.SUBSTANCE: invention is related to method for production of treated hydrocarbons gas from gas flow containing hydrocarbons and acid impurities that includes: (a) cooling of gas flow up to temperature at which mixture containing solid and potentially liquid acid impurities and vapour containing gaseous hydrocarbons is formed; (b) delivery of formed mixture to the unit and separation of solid and potentially liquid acid impurities from the mixture in this unit; in result treated hydrocarbon gas is produced; (c) delivery of heat to at least part of solid and potentially liquid acid impurities; in result at least part of solid impurities is melted and flow with concentrated impurities is formed; (d) extraction of heated flow with concentrated impurities from the unit; the method includes additionally (e) reheating of at least part of heated flow with concentrated impurities with formation of reheated recirculating flow; and (f) recirculation of at least part of heated flow with concentrated impurities to the unit. Invention is also related to LNG production.EFFECT: increasing output of treated hydrocarbon gas.11 cl, 3 dwg |
