I am trying to size relief valves for a pressure vessel that is rated for 250 psig @ 115 F it was originally designed to store liquid Propane. The vessel is made of carbon steel (SA616 for the shell and SA516 for the heads). The vapor pressure of the contents, in this case Tetrahydrofuran is only about 6 psia at 115 F. This causes the relief valves to be extremely large. I am wondering if there are any guidelines (API, etc) about relief temperature. Is it allowed to exceed the vessels rated temperature so that the relief valves could be set at a higher pressure? (The only relief case for this storage tank is the fire case.)"
