Definitions
- the invention relates to the field of cooling gaseous bodies stored in a liquefied form, and relates in particular to the cooling of a fuel gas such as liquefied natural gas (LNG).
- LNG liquefied natural gas
- Liquefied natural gas is stored in sealed and thermally insulated tanks at cryogenic temperatures.
- Such tanks can be part of a land storage facility or be installed in a floating structure, such as a LNG tank for example.
- An idea underlying the invention is to provide a method of cooling a liquefied gas and a storage and cooling installation of a liquefied gas for better control of the natural evaporation of liquefied gas while maintaining a large fraction of liquefied gas in a thermodynamic state allowing its storage in a sustainable manner.
- the invention provides a method for cooling a liquefied gas stored in the interior space of a sealed and thermally insulating tank; said liquefied gas being stored in the interior space of the vessel in a two-phase liquid-vapor equilibrium state and having a lower liquid phase and an upper vapor phase separated by an interface, said process comprising the steps of:
- sucking a vapor phase gas stream into a zone of the vapor phase in contact with a zone of the interface said step of sucking a vapor phase gas stream generating in said vapor phase zone a pressure P1 less than the atmospheric pressure so that a vaporization of the liquid phase is favored at the level of the interface zone and that the liquefied gas in contact with the interface zone is placed in a two-phase liquid-vapor equilibrium state in which the liquefied gas has a temperature below the liquid-vapor equilibrium temperature of said liquefied gas at atmospheric pressure ;
- the liquefied gas stored in the tank can be cooled to a temperature below its equilibrium temperature. vaporization at atmospheric pressure.

For most candidate materials, this constant is less than 1 and often less than 0.1. Thus, the critical buckling pressure when the tank is subjected to a depression is often more than 10 times lower than the maximum operating pressure.
