Question for the Chemist out there...
After distilling Methanol out of my Bio, I pump it into a settling tank. After sitting overnight, I get some glycerine settling out. Since there is always still some methanol in the batch even after distillation, I was curious to know if bubbling the bio would release more methanol / glycerine before dry-washing? Still have the stones from my attempt at water washing. I bubbled it for about 3 hrs while Refilling the processor. Did I gain anything by doing this?

I'm assuming you are heating the mix to remove/distill methanol from it? After the reaction and draining off the glycerin???
Any methanol not used in the reaction should leave with the glycerin. Some will distill the methanol back out of the glycerin so they can use it again. We often pre-treated our WVO with glycerin to take advantage of the unused chems still in there....
If you still have methanol AND glycerin in your biodiesel - my knee-jerk response would be you did not get a complete reaction. That would also explain your problem with water washing. I know we made a couple batches of emulsion by attempting to water wash without getting a full reaction... Then we started doing the 3/27 test and even washing a sample of the oil before mist washing.
I like the water wash because if you can wash the fuel - it is GOOD! You can't wash fuel that is not fully reacted. I've been offered homemade B100 before and after asking a bunch of questions (and not liking the answers) - took a sample and mixed it with water in a bottle. If you shake this up and create a milkshake - the fuel is not fully reacted or separated. The water should quickly separate and the fuel remain clear if the fuel is 'good'.

Bubbling air through the biodiesel will most definitely release more methanol. In doing so, more glycerine will drop out of suspension. I have a couple friends who do this, except they bubble it for a few days, then let the remaining glycerine drop out before they run it through wood chips. Me? I still water wash due to some of my equipment limitations, but I still produce great fuel.

Hey Tom, was in Sturgis all day yesterday... Anyway haven't been making near as much lately. I did get a bag of Magnesol from the Dallas Group last summer. I will try and find my contact and pm it to you. hope all is well. Hope to get a few barrels of oil from the rally and run a batch soon.
