What is the minimum rated service pressure for vapor recovery receivers?

The minimum rated service pressure for vapor recovery receivers is correctly identified as 250 psig. This value is significant as it ensures that the equipment can safely handle the pressures encountered during vapor recovery operations. Vapor recovery systems are designed to capture vapors that would otherwise be released into the atmosphere, particularly in processes involving the transfer of liquid hydrocarbons.

Having a rated service pressure of 250 psig establishes a safety margin that accommodates typical operational scenarios while also accounting for potential pressure fluctuations during the recovery process. This ensures equipment integrity and reduces the risk of failures that could lead to leaks or environmental issues.

In the context of vapor recovery systems, this pressure rating aligns with industry standards, ensuring reliability and safety in operations. Thus, using equipment rated below this minimum might not provide sufficient safety performance and could result in operational inefficiencies or hazards.
