Methanol Storage, venting
Methanol Storage, venting
(OP)
I am installing a 10,000 gallon methanol tank into a biodiesel plant, has anyone done this that can give me an idea of venting requirements, also this tank will be a double wall certified tank, will i have to have leak detection in the space between the two tanks? This project is in FL.
Thank You,

RE: Methanol Storage, venting
Methanol absorbes water and O2 from the atmoshere and becomes corrosive. We always blanket our small methanol tanks with natural gas. On a larger tank I'd investigate N2 as a blanket with a way to recylce the N2/CH3OH vapors via a compressor/surge tank.

Some important points to consider about vent systems for bulk Methanol tanks:
- The LEL and UEL for methanol are not the same as gasoline tanks; ensure that you inerting system designer is experienced and aware of the differences.

This would be a useful report for the design of your installation, but I cannot find it anywhere on the net.....can anyone help..???

and you will find the tools necessary to analyze and identify the venting requirements, blanketing, and type of relief needed by your tank.
You state you're installing secondary containment. Is this truly a "double" tank? I've done secondary containment with raised MeOH tanks inside a concrete containment area and this is less expensive and more flexible that a "Double" tank.
