What Is LNG Storage Tank

LNG can be used to supplement or replace diesel fuel in High-Horsepower engines utilized in the shipping industry, the oil and gas industry, the rail industry, mining, and over the road trucking.
LNG must be stored and distributed with specialized equipment and stored in insulated tanks in order to keep the fuel in a liquid state at minus 260° F.

A liquefied natural gas storage tank or LNG storage tank is a specialized type of storage tank used for the storage of Liquefied Natural Gas. LNG storage tanks can be found in ground, above ground or in LNG carriers. The common characteristic of LNG Storage tanks is the ability to store LNG at the very low temperature of -162 °C (-260 °F). LNG storage tanks have double containers, where the inner contains LNG and the outer container contains insulation materials. The most common tank type is the full containment tank. Tanks vary greatly in size, depending on usage.

In LNG storage tanks if LNG vapours are not released, the pressure and temperature within the tank will continue to rise. LNG is a cryogen, and is kept in its liquid state at very low temperatures. The temperature within the tank will remain constant if the pressure is kept constant by allowing the boil off gas to escape from the tank.
