Pressure relief systems are vital in the chemical process industries (CPI) for handling a wide variety of situations. They are used to prevent pressurization above a system’s design pressure; for venting during an unusual or emergency situation; and for normal depressurization during a shutdown, as examples. In some cases, such as when non-combustible gases including steam, air and nitrogen...
