Compared to vacuum tanks and spherical tanks, cryogenic storage tanks exhibit better safety due to their lower storage pressure. These tanks have been scaled up to larger sizes, occupying less land and reducing storage costs
With the development of science and technology, the technology of storing materials in low-temperature storage tanks under normal pressure is becoming increasingly mature. The construction of domestic low-temperature storage tanks under normal pressure is increasing, moving towards large-scale development. Compared with other storage methods, normal-pressure storage tanks have many advantages: compared to vacuum tanks and spherical tanks, due to the low storage pressure of low-temperature storage tanks, they have better safety. As low-temperature storage tanks achieve large-scale development, they occupy less land, reduce storage costs, have a simple structure, are easy to construct, and lower construction costs. Common storage media include liquefied natural gas (LNG) (-162°C), liquid oxygen (-183°C), liquid nitrogen (-196°C), liquid argon (-186°C), liquid ethane (-89°C), ethylene (-104°C), etc.
