I was working at a refinery awhile back and had a quesiton that no one could answer.
I was looking up at some of the PSV's on the towers that wer not vented to the flare. All of these atmospheric relief safety valvs had a small spool that came out of the horizontal exit and then made a 90 degree bend upwards and then were cut on an angle at the atmospheric exit.
Does anyone have any idea why this is the case?
Some of the answers I got:
1. So birds don't nest in them
2. So they don't whistle
3. So the pressure is released gradually as it exits at the slash
thanks,
Andrew
