The design temperature of the tank is usually in the range of -20°C to -30°C (-4°F to -22°F)
Cryogenic carbon dioxide storage tanks are used to store liquid carbon dioxide (CO₂) and adopt a double-layer structure.
At room temperature (20°C or 68°F), the saturated vapor pressure of liquid CO2 is about 57.8 atmospheres (5.8 MPa). To keep CO2 in a liquid state, the tank must be able to withstand at least this pressure.
