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…

One of the more complex situations for control valve failure is associated with the level control on the liquid bottoms of an upstream vessel operating at a pressure significantly higher than the downstream system.  Opening…

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…
