What is the pressure specification for a cryogenic liquid cargo tank?

• A. Above 100 PSI
• B. Less than 22 PSI
• C. Between 40 to 60 PSI
• D. Less than 4 PSI

Answer: (B)

The pressure specification for a cryogenic liquid cargo tank is generally less than 22 PSI. This is because cryogenic liquids, such as liquefied natural gas (LNG) and liquid oxygen, are stored at very low temperatures and under low pressure to maintain their liquid state. High-pressure conditions could lead to hazardous situations such as tank rupture or rapid vaporization when the liquid comes into contact with warmer environments. Maintaining operating pressure below 22 PSI is critical for safety, as it reduces the risk of leaks and allows for safe transport and handling of cryogenic materials. It is important for safety protocols and equipment design to align with these pressure specifications to ensure the integrity of the cargo tank under all operational conditions.
