[b]Fuel Gas as a Blanket[/b]

[b]Fuel Gas as a Blanket[/b]

(OP)
We are thinking of using fuel gas as a blanket for our ethylene glycol storage tank.  The boiler for the glycol is downstream approx. 10-15 feet away.  Is it a bad idea to have a fuel gas blanket on a vessel so close to an ignition source.  Does anyone know what code or standard gives spacing regulations regarding these situations?

RE: [b]Fuel Gas as a Blanket[/b]

Consider checking NFPA 59, Utility LP-Gas Plant Code.
 

RE: [b]Fuel Gas as a Blanket[/b]

Why are you putting a pad gas on ethylene glycol anyway?  If it was me I would not put a flammable gas on top of a relatively inert fluid.  It just makes things more difficult.   Why not just put a concervation vent on the top of the tank or pad with N2?
