Hello Michael
Other than water in the WVO and Methanol there are at least two other sources:
1. Atmospheric water vapor tries to establish equilibrium with
everything (including all feedstock and reagents used in the BD
process).
2. The catalyst widely used in homebrew, dissolved lye

I am probably missing something, but where would the water be coming from in the first place? Isn't the waste oil you start with not supposed to contain any water, and if it does, you need to boil it off? Then there's the methanol. It should not contain any water either. I don't believe the

If using the Acid process you will generate some water. Also remember
the oil is dry but there are trace amounts of water in the best grease
but I dont think this causes a problem.

This is true for tray towers. A more elegant setup is a

You can build a well insulated, e-glass, almost-walk-in, oven for $200.
I wouldn't buy one.

Yes, and you probably did. This is why they use distillation columns in
industry.
Zeolytes should work. Just make sure that whatever one you choose is

without getting into excessive detail, the boiling point of a mixture is
the weighted average of the stuff present. At first you have pure
methanol coming off. as the temperature rose, increasing amounts of
water contaminated the alcohol.
You need a fractionating column to obtain pure
good results with the
wash test.

Andrew
