One of the 8" vents should be able to move all the gas by itself without exceeding the maximum tank pressure (1 psig).
It just seems like with that amount of gas there might be a pressure surge greater than 1 psi the instant that the PSV pops. Does that make sense?
There is a PSV set at 1440psi piped to a 400bbl tank through a 2" line. The maximum gas rate through the PSV would be about 10 mmscf/d. The tank is venting through two 8" vents.
Does anyone know how I could calculate the pressure in the tank the instant that the PSV vents gas to the tank?
I'm working on a project where we're exposing a pipeline while it is in service to repair some damaged coating. I'm wondering how to figure out the maximum allowable stress due to the bending of the pipe, so that I can decide how much pipe to excavate at one time. Any help would be greatly...
