Hello guys... I would like get a final answer regarding this as I have read statements for and against it. So does crude coconut oil (freshly pressed from...
Bill, I do my 3/27 test before I remove the methanol, the excess aids in the reprocess (there is residual catalyst as well). I would assume, it would depend on...
Richard, When using the 3/27 test, how can we tell if the bio is grossly under processed or just slightly under processed? Sometimes I get just a little bit of...
Tom, For me to answer your question, I would have to paraphrase the following web page: http://www.biodieselcommunity.org/methanoltest/ This a good source of...
Coming out of the cave ..I just happened upon an issue of Scientific American Dec 08..And on the 8th page was an article about this company..Upon looking up...
I finally ran out of NaOH and am ready to start using 2 big bags of dry chinese KOH that say 90% purity. To pass 3/27 test I had to go up to 900 grams NaOH for...
... Actually, I get by with quite a bit less. Conversion is dependent on a lot of things, the most important of which are process temperature, processing...
I am wondering if a processor calibration error has resulted in this odd discrepancy in how much lye to use. 30 gallons is 113.5 liters. With oil that titrates...
Doug, Multiply your NaOH number by 1.4 to get an equivalent with KOH, 90% purity you will need to divide by .9 (900 * 1.4 = 1260 / .9 = 1400) Rick ... From:...
Perhaps you are right about the calibration. I have the typical poly clear site tube run up the outside of my sealed insulated 55 gallon steel drum. I...
Actually, the 3/27 test doesn't indicateglycerin. It only indicates di and triglycerides (unreacted oil). HTH, Gary ... From: dougwene <dougwene76@...>...
There's no way to get glycerol in your fuel filter unless you aren't washing completely, Doug. Glycerol is water soluble, so when you mist wash and bubble...
... It's easy enough to test if he still has some of it around. It could be glycerin, soap, dirty water, or oil crud. Glycerin will burn and dissolve in...
I think there needs to be some clarity. As Rick mentions figuring in the purity. It should be noted that this is for converting the math over to KOH from NAoH....
"So a gallon of cold hydrogenated oil becomes less than a gallon of warm hydrogenated oil." Maud, do you mean becomes "less WHEN a gallon of...." otherwise...
Yes, I agree that a new titration should be done using the KOH you have. My intent with the math was to give a ballpark indicator of how much KOH was needed...
Doug, The purity of the NaOH may also affect how much is needed for conversion. You could check the purity of the NaOH by doing an acid titration of the NaOH....
Greetings all-- Been Lurking for a long time. Looking for a discussion on the controversy over the need to wash the fuel. I'm sure I've seen it over the...
I don't follow your confusion. I can just tell you what happened. I calibrated the first half of my processor with cold hydrogenated oil, marking off the...
There's no controversy over washing. You will find individuals who will say they've never washed a drop of fuel in xxx,xxx miles and never had any trouble. Ho...
Two 15 gallon batches using 13.8 grams KOH, three washes + magnasol. Washing temp was 65*F. Finaly came clear after two weeks of average temp 50*F. Both passed...

To the person who said his feedstock or product lost volume when he heated it: I think it was an illusion. When you heated the system, the steel container...
The volume of ice is reduced when it thaws! ... From: Louis James <loujam35@...> Subject: [Biodiesel] Shrinking Liquid To: Biodiesel@yahoogroups.com ...
Hydrogenation 'puffs up'Â liquid oil similar to freezing water (hence pipes burst when frozen). Consequently liquefying semi solid hydrogenated reduces...
OK. Processed in a 20 gallon Appleseed (working volume 12 gallons WVO) 1500 Watt element, WVO dewatered by settling after filtering to 50 micron with...
I'm the one who said it, Lou. Hydrogenation "plumps up" oil molecules at room temperature. When a certain volume of solid hydrogenated oil is heated, the...
Water is one of the very few substances that expands on freezing. About 4% by volume. All oils, whether hydrogenated or not, will expand on heating, and when...
