Re: [Biodiesel] Re: glycerine pretreatment poor separation

 

Yes indeed... lots more work and time with less biodiesel in the end.  Why do you do this?  I don't see how you can use a filter to separate the glycerin.  I've run glycerin thru a 1 micron filter just to see what would happen and almost all of it went right thru the filter.

I distill 40 gallons of MeOH/glycerin at a time and usually recover 5 gallons of beuatiful MeOH. It costs me $3/gallon to buy MeOH and the electrical costs for 24 hours of distillation mean that I pay $1/gallon for recovered MeOH.
