Pressure relief valve at the outlet of the hydrogenation reactor
Thread Content
The last edit to this post was made by QD guy on 2015-7-18 06:19. Why are two pressure relief valves always installed after the hydrogenation reactor, and why are they used simultaneously, with one having a bypass line and the other not?
Why is there a pressure relief valve at the outlet of the hydrogenation reactor? Could you please explain it? Also, your question mentions a pressure valve, and I’m not clear about that. (Why are two pressure valves installed after the hydrogenation reactor?)
Pressure relief valve? Attach a flowchart or a simple diagram; I’ve never seen a pressure relief valve at the reactor outlet~~~~
Without a flowchart, it’s unclear what is being referred to? As far as I know, pressure relief valves are located in critical positions; they are installed as a backup to each other so that operations can continue in the event of a problem. When used simultaneously, one unit has a fixed small opening degree while the other is used for adjustment. The secondary line you mentioned should be the one common to both valves, not one having it and the other not.
Is what the poster is referring to a pressure relief valve ordered from high pressure to low pressure?
