FIELD: chemistry; technological processes.
SUBSTANCE: gas chemical complex providing processing of natural hydrocarbon gases of various deposits can be used in gas industry under conditions of its intensive development. Complex comprises a gas processing plant, a gas chemical plant, a methanol and mineral fertilizer production plant, natural gas liquefaction plant and gas-transport network uniting plants to each other, natural gas of one or several deposits of gas-producing region is supplied to gas processing plant, successively subjected to purification from mercury, methanol, acidic impurities in form of H2S and CO2, drying and low-temperature fractionation with separation into methane, ethane and wide fraction of light hydrocarbons (WFLH), wherein at natural gas liquefaction plant water vapor obtained by recuperation of flue gas heat of gas turbine drives of compressors is used to cover requirements for water vapor of auxiliary needs of liquefaction plant and / or is supplied to gas processing plant and / or to gas chemical plant, and / or to plant for production of mineral fertilizers during commissioning works, and / or during normal operation, as well as to steam drives of heat power plant for generation of electric power and / or to other consumers outside the complex, at that water vapor of low pressure (LP) and / or medium pressure (MP), and / or high pressure (HP) is obtained.
EFFECT: invention enables to use internal energy resources to produce water vapor as an industrial heat carrier covering the complex needs.
