Storage Conditions for Air Separation Equipment

While the air separation unit itself is a gas separation facility and does not directly "store" products, its accompanying liquid storage system is utilized to store cryogenic liquid products such as liquid oxygen and liquid nitrogen.

 

Cryogenic Environment: The storage tanks must maintain a temperature below -180°C to ensure the stable storage of cryogenic media, such as liquid oxygen and nitrogen.

 

Thermal Insulation Structure: Storage tanks typically employ a double-walled vacuum insulation structure-or utilize powder/high-vacuum multi-layer insulation methods-to minimize heat ingress.

 

Pressure Control: These storage tanks function as low-pressure vessels (e.g., flat-bottom tanks); their design pressure must be compatible with the overall system requirements to ensure safe operation.

 

Material Compatibility: All components in direct contact with the cryogenic liquids must be constructed from materials capable of withstanding ultra-low temperatures to prevent brittle fracture.

 

Safety Configuration: The tanks are equipped with various safety devices, including automatic leak detection systems, pressure relief mechanisms, and seismic-triggered interlock shut-off systems.
