FIELD: production facilities.
SUBSTANCE: invention relates to production facilities and can be used in the creation of complexes for the production of liquefied natural gas (LNG) based on gravity type in the coastal and marine areas. The complex for the production of liquefied natural gas (LNG) contains at least two bases of gravity type 4-6 (GTB), on each of which there is a technological line 1-3 for liquefying natural gas using a mixed refrigerant, including installations for receiving and treating raw gas, gas condensate stabilization unit, gas dehydration and mercury removal unit, wide fraction light hydrocarbon (WFLH) recovery unit, refrigerant preparation and compression system and liquefaction unit. At least one GTB 4 (5, 6) of the production line 1 (2, 3) includes a fractionation unit for obtaining mixed refrigerant components from NGLs and at least one corresponding GTB 4 (5, 6) has at least one reservoir for each component of the mixed refrigerant. Each GTB 4 (5, 6) has at least one LNG storage tank. At least one GTB 4 (5, 6) has at least one storage tank for stabilized gas condensate (SGC). At least one GTB has berth 7 (8) for offloading LNG and SGC to tankers. At least one tank for each mixed refrigerant component is connected by pipelines to the refrigerant preparation and compression systems of all production lines to form a single system for replenishing mixed refrigerant components. At least one SGC storage tank is connected by pipelines to the condensate stabilization units of all production lines to form a single SGC storage and shipment system. LNG storage tanks are connected to each other by pipelines to form a single LNG storage and shipment system.
EFFECT: invention makes it possible to exclude excessive duplication of equipment by creating common technical systems for the entire complex.
