FIELD: gas industry.
SUBSTANCE: invention relates to gas production, gas processing and gas chemical industries. Natural gas liquefaction complex includes two gas and/or gas condensate fields 100 and 200, complex gas treatment plants (CGTP) 101 and 201 of the first and second fields, preliminary treatment and drying units 111 as part of CGTP 101 and 211 as part of CGTP 201, units for cleaning from acidic impurities and heavy hydrocarbons and drying of raw gas 112 as part of CGTP 101 and 212 as part of CGTP 201, units for recycling acidic impurities 113 as part of CGTP 101 and 213 as part of CGTP 201, BCS 114 as part of CGTP 101 and 214 as part of CGTP 201, gas fractionation unit 215 as part of CGTP 201, after-drying units 301 and liquefaction of natural gas 302 as part of LNG plant 300, as well as consumers 400 and gas chemical production 500. CGTP boosting compressor station of the first deposit is connected to a pipeline of a part of purified and dried natural gas of the second deposit, and CGTP boosting compressor station of the second deposit is connected to the gas fractionation unit by pipelines of a part of compressed cleaned and dried gas and methane fraction.
EFFECT: higher quality of commercial gas and efficiency of gas chemical production.
