They will need methanol for the process, you need to find out about methanol
tanks size as well.

Steve,
I thought this project was dead, but apparently not.
The basics: The building is 5100 sqft. There are 3-5000 gallon tanks
of either glycerol or veg oil, with a plan for a fourth. I have no
idea what size the process tanks area, but there are two parallel
production lines. There is no data on outside storage, but there has
to be some.
The specifier (I'm not using Engineer, because there is no evidence
of engineer involvement) called for a 0.40 density over the whole
building with 100 sqft sprinklers (even though he drew sprinklers at 144 sqft)
To me, it sounds like they need some serious engineering in order to
get this right. I'm not sure how far I want to get into it until
someone "shows me the money"
Any thoughts would be appreciated. Have a good weekend.
Todd

Todd,
Yes, I just finished a biodiesel facility. A straight EH2 approach doesn't
really cut it for the indoor storage of some of those liquids. It depends a
lot on what sizes and arrangements of tanks you will have, where the
methanol is, whether the process is indoors or outside, etc. Basically, the
biodiesel itself and raw oils such as cottonseed, palm, and corn oils are
class 3B liquids typically, but the methanol and sodium methoxide are the
nasty ones (class 1B). Additionally, there is a point in the process
typically where the mixing has already occurred but enough free methanol can
still be present in the mixture to classify the entire vessel contents as
class 1B. We used a closed head foam system indoors and an open head deluge
system over a separate methanol storage area. I highly recommend foam for
this application versus just water at a high density as you initially
mentioned. Feel free to give me a call or email if you would like to
discuss it in more detail.
Good luck,
Steve Kowkabany, P.E.

I have been asked to look at some criteria for a small (2500 sqft)
biodiesel processing facility. Someone (I'm not sure who) defined
this as a Class !B flammable liquid and called for a 0.40 gpm/sqft
density over the entire building area. While I'm not necessarily
challenging this, I cannot find anything to verify it. NFPA 13 and 30
seem to focus more on storage than processing. Has anyone else run
into this yet?
