Solvent storage tank (alcohol based product) and Flame Arrestors

Solvent storage tank (alcohol based product) and Flame Arrestors

(OP)
Would a solvent storage tank require a flame arrestor if it already has a pressure relief valve or emergency vent?
 

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

What's the solvent, what's its classification, and where is someone telling you need a flame arrestor? It sounds like someone want the device in the tank emergency vent discharge, but that's only a guess.

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

(OP)
The solvent is a mixture of ethanol, methanol and propyl acetate.  So the classification is IB.   

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

Where do you want/need/desire to install the flamer arrestor?

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

(OP)
on the tank

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

In all three companies I've worked for, where a PRV or emergency vent is provided, flame arrestors are normally not provided.

Good luck,
Latexman

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

Since you won't say where your going to install the flame arrestor, I'm going to assume it's either on the tank's normal vent or emergency vent. In either case, an in-line flame arrestor is not required by NFPA 30 or the 2009 International Fire Code.

RE: Solvent storage tank (alcohol based product) and Flame Arrestors

(OP)
Thanks.  I am sorry, it was going to be installed on the normal vent.
