TANK FOR STORAGE OF LIQUEFIED NATURAL GAS OF INCREASED RELIABILITY Russian patent published in 2019 - IPC B65G5/00 

FIELD: gas production industry.

SUBSTANCE: invention relates to underground storage of liquefied natural gas (LNG), namely, highly reliable fire and explosion-proof tanks, and can be used for backing up, storing and delivering LNG to a consumer, especially where there is not enough or no pipeline natural gas, as well as to cover peak gas consumption. Tank is divided into sections, the number of which depends on the volume and height of the structure, as well as on the requirements for reliable storage of LNG. Separation of the tank capacity is performed by pre-stressed plates arranged in parallel, relative to the surface of the bottom plate of the structure. According to the invention, the use of more than one main storage volume is ensured, and several volumes separated by structural and heat-protective elements. Improving reliability, safety and durability is achieved by changing the design of the tank capacity, since the explosion of one of the sections, the other sections will function without changing the operating mode, which will allow to ensure the uninterrupted LNG to consumers. Location of the tank at depth provides protection of the tank against possible destruction as a result of man-made activities or sabotage acts.

EFFECT: invention provides a high degree of fire safety and explosion safety when committing a terrorist attack on a given object, also in case of accidents and various man-made impacts; possesses environmental safety during long periods of storage of LNG and storage operation.
