What should the maximum designed pressure for a fuel oil storage tank be?

The maximum designed pressure for a fuel oil storage tank is typically set at 100 kPa. This pressure setting is based on safety standards and industry regulations that account for the properties of fuel oil and the design parameters of storage tanks.

Fuel oil is classified as a relatively low-pressure liquid, and maintaining a maximum pressure of 100 kPa allows for safe storage without excessive risk of failure or leakage. This pressure limit also ensures that the structural integrity of the tank is not compromised, while still allowing for adequate venting and pressure relief systems to function effectively in case of expansion or temperature increases.

Setting the design pressure too high could lead to unnecessary engineering costs and complications in the design and operation of the storage tank, while a lower pressure limit might not adequately account for the conditions that can occur during operation. Therefore, 100 kPa is a widely accepted standard for the maximum designed pressure in such systems.
