YIKES! Sounds like a good place to store the methanol and caustic too... Wink
DD, Your on!
We would have more fun heading up north for a moose or a bear though. I am new to this area and you need to know the local farmers to find a place to hunt around here, its fairly populated in these parts and everything is posted with no crown land anywhere to be seen...
I have been so busy over the last couple years I have only looked at my hunting gear with a fond look and glazed over eyes... Its amazing how starting a family and moving out of the north can interfere with a guys bush time. Roll Eyes

new batch in at 2pm. Neutralized processor with acid and water flush, dewatered oil
T 14 to start. .12 mult to see if it helps compensate for mixing. 155F. 2 hrs later T 7. will check it later this evening.

we'll just have to see how low it goes and what the yield ends up at

-I noticed you had to did two repos on the last batch, you may find you have better results by spliting up your base stages into a 90/10 or 95/5 this works better for me than 80/20 which most times required a repo. Tom

Tom, Ill try that. It did pass 3/27 after the first repro, but after the second it passed 9/27 easily
I never got out to the barn last night to check the T. Checking it here after my morning coffee.

T is now a 3. I turned the pump and heat off last night at 6pm, let it ride as it was until just now.
Interesting. 14 to a 3 in 15 hours. No draining

A word of caution for those of you mixing during the acid stage. I have recently been in contact with MP Pumps for some pump information and their tech wanted me to look over a synopsis he wrote about some problems they have had with biodiesel facility's. Their cast iron pumps were failing in the biodiesel process, to quote
quote:
The ductile iron in this unit was dissolving away at a rate that was requiring the housing to be replaced every 6 to 12 months
They have resolved it by using a cast stainless steel pump. I would assume that it was acid processing that caused the failure...
The synopsis also address's the failure of the viton pump seals due to the methanol and they have rectified that by using Teflon seals...

I attached the document if any of you care to add anything. I used track changes to make it easy, my comments are in red.
Just change the file extension from .txt to .doc

Thanks for the info Jon.
My pump is Bronze housed with packings. Cool

Hook, mixing hurts ending T with both HTAE and AE, but is a neccassary component for HTAE to keep the methonal mixed in.

You need to use a tube sock (or equivalent) full of sodium bentonite to counteract the negative effects of mixing. HTAE can easily drop T of 11 to completion in 1 hour, also your acid can be cut in less than half and get about the same result. Higher temps makes for even better finish T and even faster finish if your reactor can handle it.

Also a refractor tower is a must to keep the methonal in the reactor if you can't seal it.

Biotom is right about the caustic, his findings changed my setup and helped me remove the remaining inconsistencies.

methanol containment is not a problem, neither are temps, I can take it as high as I wish if needed. Problem is the sodium bentonite. I dont have any way to make use of it because my reactor is 100% sealed( not counting vent line with shut off)
I use the apple turnover design with a few of my own modifications to suit my needs.
Any ideas on how I could make use of the SB?

I'd like to hear where mixing hurts ending T comes from, I mix continuously during 150 degree AE, today my 300 gallon batch went from 9 to 1.75 in three hours.

fab, there were a few tests done that showed mixing hurt ending T vs non mixing and hlding temp at 130F

One question for you. On your ae, which at 150F could be considered HTAE, how many gpm or LPM are you running? I running at 20 gpm, and have seen pretty quick drops inside of 3 hrs using HTAE, but not finished T's inside of 3 hrs, more like 12-15 hrs at 155F

125 gpm, I have never had an AE go longer than three hours, even with oil that starts at ten or eleven.

increased mixing then explains the short times.

Are you using sodium bentonite?

No, I don't see a need for it in my process.
