Selection of steel for cryogenic storage tanks

The thermal insulation design of liquid nitrogen storage tanks is a key factor in ensuring efficient and economical operation of liquid nitrogen storage tanks. Excellent thermal insulation properties can minimize the evaporation and loss of liquid nitrogen.

An air-heated vaporizer is a device used to vaporize a liquid sample or solution into a gaseous state

Thermal evaporators use temperature differences in the air environment as a heat source. Heat is exchanged through an aluminum star-shaped fin tube with good thermal conductivity.

Since LNG storage tanks involve high pressure and extremely low temperature environments, safety is a key factor in design and operation.

Both vertical and horizontal LNG tanks have a liquid level meter in a prominent position, now mainly differential pressure level meters, which work on the principle that when the liquid level in the container changes, the static pressure generated by the liquid column also changes accordingly.

When the facilities around the area of the LNG leakage fire are threatened by the burning heat of the flames, the storage tanks, equipment and pipelines that are not on fire should be insulated and cooled down.

The LNG storage tank is made up of an interior container, an outside shell, support, a process piping system, thermal insulation materials, and other parts.
