INTEGRATED COMPLEX FOR PRODUCTION OF LIQUEFIED NATURAL GAS (LNG) ON GRAVITY-BASED FOUNDATION (GBF) Russian patent published in 2022 - IPC B63B35/44 E02B17/02 E02D27/52 F25J5/00 F25J1/02 F17C1/00 

FIELD: gas industry.

SUBSTANCE: liquefied natural gas (LNG) production complex comprises a gravity-based foundation (GBF), on the upper plate of which there are superstructure modules, including connecting modules 35–38, located along the middle line of the upper GBF plate 2, and equipment modules, at least part of which is located in one row on each side of connection modules 35–38. Inside the GBF there are reservoirs 12, 15, 17 for storage of liquids. Equipment modules include located in the first row on one side of connecting modules 35–37 module 28 of receiving structures, condensate stabilization unit and acid gas removal unit and mixed refrigerant compressor module 32 (33); located in the second row on the other side of connection modules 35–37 are modules 29–31 of gas dehydration, mercury removal, extraction of a wide fraction of hydrocarbons and fractionation and liquefaction, as well as a boil-off gas compressor module 34, a fuel gas system and a heat carrier; as well as equipment modules include power plant module 39 located along GBF end, module 40 of the main technical room and emergency diesel generators and module 41 of auxiliary systems.

EFFECT: invention solves the problem of expanding the range of LNG production facilities in the coastal zone of the water area with severe ice conditions.
