Isothermal tanks are used to store liquefied hydrocarbon gases LPG, LNG, ammonia, ethylene, propylene and others at a boiling point of gas below 0 ° C and a constant overpressure close to atmospheric (no more than 0.12 MPa). Isothermal LPG tanks are manufactured with a volume of 700 m3 and more. The isothermal method of storing liquefied gases is convenient both for storage and for road and rail transportation of gases: the volume of gas during liquefaction decreases up to 1500 times.
Benefits of using isothermal gas storage tanks include:
Metal consumption for the manufacture of isothermal tanks is minimal compared, for example, with the metal consumption of cylindrical tanks for storing the same volume of gas.
