Safety Valve vent stack sizing
Safety Valve vent stack sizing
(OP)
Greetings,
Does anybody have recommendations on techniques for sizing vent stacks on PSV discharge stacks; open or closed. I am familiar with the techniques of Benjamin, Liao, B31.1, and Miller of the BHRA.
Has anybody experience blowback on vents sized with any of the above techniques?
Chris

I have not read API RP 521. My employer doesn't deal with API specifications often so they are not kept up to date.

Do you know why the B31.1 App II did not include the min. back pressure correlation that Liao has? Perhaps it was covered in the B31.1 equation for the chocking pressure?
