Sudden tube ruptures in shell and tube heat exchangers operating at a high differential pressure in which the low pressure side contains an incompressible fluid and the high pressure side contains gas have been recognized…

There are several controls used in a facility in various ways that directly affect the relief system design or design basis, and are critical to the design of a pressure relief system.  While there are…

An inadvertent mixing of hot and volatile fluids can result in overpressure if the volatile fluid is vaporized and sufficient volumetric accumulation occurs.  Hot fluid temperatures exceeding the bubblepoint temperature of the volatile fluid is…

The potential for heat input from an external fire resulting in the overpressure of a pressure vessel is one of the most common overpressure scenarios identified in processing plants.  Reducing the required relief rate can…
