STORAGE OF LIQUEFIED NATURAL GAS Russian patent published in 2011 - IPC F17C1/00 B65G5/00 E04B7/14 

FIELD: construction.

SUBSTANCE: storage is arranged below earth level (1), is enclosed along the perimetre from the soil massif with a concrete wall of "wall in soil" type (2) and comprises a reinforced concrete reservoir (5) arranged on the base from compacted soil (3) and a heat insulation layer (4), and this reservoir at its external side surface is surrounded with a pliable layer (6) and is coated from inside with layers of heat insulation (7) and hydraulic insulation (8). The storage is equipped with a process well that exits the reinforced concrete reservoir to earth surface. On the concrete wall of the "wall in soil" type there is a support reinforced concrete ring (14), where guy ropes (15) coated with anticorrosion material are attached to support the roof of the reinforced concrete reservoir. At the external side of the concrete wall of "wall in soil" type from the level of the reinforced concrete reservoir roof to earth surface there is a conical or stepped mine filled with a layer of light heat insulation material (13) together with the roof of the reinforced concrete reservoir, guy ropes, support reinforced concrete ring.

EFFECT: possibility of increased capacity storages construction.
