Dear all,
As far as I know, a flare system usually includes flashback seal drum and flashback prevention section as in picture below:
However, the flare system in some gas processing plants I know does not include any flashback seal drum or flashback prevention section. It just includes K.O Drum and there is a "annular slot" in the flare stack. I wonder if it is safe and the "annular slot" could play the role as a flashback prevention section?
Thanks in advance,
Hoang
