Dear Bobby,
In the light of the given information including molar flow rates, I modeled it on software basis and and also check some documentation such API 12J, accordingly regarding diameter seems not problematic considering lenght appr. 6 times more than diameter! However as for internals, in DS provided there are several internals for that system such as, inlet diverter, mist eliminator and it is not given explanation on it but maybe one baffle, coalescer or foam breaker shown as just dashed line as one line I am not sure what is these internals. System is working such 2 phase diverter and gas is on going to flare and liquid is transfering to recycle tanks. At that moment what is your recommendation, not putting any internals to drum, and how can I provide reference about that issue because I need to give certain explanation and references, unless I am using internals?
Thanks for your kind replies.
