Inlet Latent Heat -This term is an estimation used in sizing pressure relief valves for two-phase liquid/vapor applications when the system has less than 0.1 wt% H2, a nominal boiling range less than 150°F, and is far from the critical point. It’s important to note that true “Latent...
Control Valves InPipeline Rules of Thumb Handbook (Eighth Edition), 2014 Sizing methodologies The code describes three methods to provide adequate relieving capacity for a pressure vessel. These methodologies are applied based on the characteristics of the relieving system, not individual components. ...

To get you started on scenerios,things like any thermal input, fires, heaters, solar radiation can cause a pressure increse. Mechanical equipment like pumps and compressors. These mechanical sourses of pressure increase are from failures of control valves or ESD systems as well as human error. ...

This may lead to chatter and It is generally found that applying the API 521 relief-valve sizing methodology, the relief valves are grossly oversized compared the actual size used in the dynamic simulations where a D-orifice is sufficient to keep the vessel pressure below 121% of the design ...
