Vent header purge rate

Vent header purge rate

Vent header purge rate

(OP)
I am looking at the purge rate of fuel gas in our vent header. I have used the Shell DEP to calculate the required min purge rate, which is a function of diameter of the vent tip and the Mr of the purge gas. The purge gas is injected at the far end of the vent header.

It appears the same method is used to calculate the min purge rate for both flared and non-flared systems. Without going outside the DEP, I am interested to know if there is justification for reducing the purge rate for a non-flared system.

Thanks,
Mark
