sizing of Nitrogen purge nozzle

(OP)
Dear Friends
I have a pentane tank 20000 m^3 capacity and i want to know what size of nozzle can i use for Tank  Nitrogen purge ?is there any refrences for it?

RE: sizing of Nitrogen purge nozzle

rezapayman,
It will depend on how quickly you want to purge, and consequently the size of your nitrogen generator. We hired a unit that could do 500 Sm3/h, but we were only purging LPG bullets of around 2000m3, and related piping. The generator had a 2" outlet, so that's the size hose we used.

Connection to the bullets for the purge was via branches in the attached piping, not via specific nozzles.  

Cheers,
John
