Dear all,
I am trying to find out the nitrogen quantity required to be used to inert a non-continuous flare at star-up.
In the standards that i have, like API, i found indications regarding the purge gas used during flare operation, in order to avoid air ingress.
But what about start-up? I should bring the O2 level to 6% also, starting from lets say 21%?
The method with system pressurization up to 2-3 barg i think i cannot use it because the system is open to atmosphere.
If you have any suggestions i will be very grateful!
Thanks!
