Hello Guys,
Is there any requirement/recommendation (preferably a reference to a standard like API 521 or a code) about the sweeping/purging gas for the flare header?
I see it is common that the essential purging gas is applied at the end of the flare header. My question is that what happens if we apply the purging gas at the base of the flare stack (to a mount exceeding flame velocity by a margin—to prevent fire flashback) and not at the end of the flare header?
Thanks
