Electrical process removes Glycerol

Postby leftcoastjeff » Fri Nov 07, 2008 1:14 pm

Have any of you seen/done this on WVO
Electrical process for removing Glycerol
1000 volts to start, up to 2000 volts as the Glycerol drops out
Low amps, around 20MA
My Question is,
Is the H2O being removed bonded with the Glycerol?
Makes sense to me.

8000 volts, 20ma

There is no glycerol in VO to be removed, its only in biodiesel. I haven't heard of anyone testing it on VO for dewatering.

Thank you for your response,
I understand that there is no glycerol in VO to be removed, its only in biodiesel. (byproduct of process)
What component is being effected, the glycerol or the water associated with it?
I know that water (with some salts) conducts electricity.
How about the glycerol alone?

Did you see the voltage go up as the glycerol settled, very interesting.

I agree,I haven't heard of anyone testing it on VO for dewatering.
Sounds like a good reason to ask, then experiment.
Have you heard of anyone measuring resistance of the oil to check for water?

I may be way off base, but the only dumb question, is the one not asked.

VO is an insulator, it has infinite resistance so you can't use that to test. There are meters for water in VO that use capacitance, and they are very expensive.

both these videos if I understood it right was about removing soap/glycerin from BioDiesel.

There were other videos listed on the sides about using ultrasonics for making biodiesel W/out triesterfication. Or they miss labled the video's and it was all the soap removing via ultrasonics. The lanugage in these videos was Korian I think so Im not sure.
