After producing liquefied gas through cryogenic method, it is vital to store it under certain conditions so that it can be exploited when needed. Liquid nitrogen, oxygen, and argon storage tanks are known as cryogenic tanks, which have the ability to store these liquids at very low temperatures. These pressure vessels have a double-walled structure in them the gap between two walls is completely insulated with very high thermal resistance. In addition, the middle gap has a relative vacuum, which leads to the minimum heat transfer from inner vessel to the surroundings. These storage tanks can be manufactured with the capacity of up to 300 cubic meters
