Wetted surface area calculations for fire-relief sizing in ASME pressure vessels
Although individual operating facilities take many steps to protect plants from fire, pressure vessels within a fire zone must be protected by a pressure safety valve (PSV). Proper calculation of the vessel’s wetted surface area is a crucial step in properly sizing a PSV.
Protect tanks with pilot-operated vent valves
A number of devices are available for protecting low-pressure American Petroleum Institute (API) tanks against overpressurization. A case study demonstrates the need for the designer to analyze the en..
