Regarding the relief of safety valves
Thread Content
May I ask how to determine the diameter of the discharge pipe for a safety valve? I’m confused why, for some gases with a large volume, the discharge pipe diameter is small, while for others it is large. I hope experts can help clarify this. I am extremely grateful. How to determine the pipe diameter if a large amount of inert gas is discharged from the top of the tower?
There are standards for all of this, and it needs to be calculated.
The discharge pipe diameter is related to the process safety requirements for back pressure and operation.
Some time ago, I carried out some calculations regarding safety valves; the diameter of the discharge pipe is related to the properties of the material, the back pressure, as well as the design parameters of the equipment itself. You’d better check the professional standards; I did my calculations based on API521
