An acquaintance did a test and got about %4 back from a batch using %16 methanol. I assume then that the bd reaction only uses 10-12 percent. this is not scientific, but I think that since you are not only making your glycerin non poisomous, and reusing the "waste" methanol, it is worth the effort even at smaller returns than that. Also, if you are recovering the methanol, you can use more of it for a better reaction without a cost penalty.
What does anyone have to say about pretreating the biodiesel with the leftover weaste glycerin with the methanol still init? mix the glyc, whicvh has meth and NAOH, then do a reaction with a corresponding lesser amount of reactants... anton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, November 30, 2001 2:15 AM To: biofuel@yahoogroups.com Subject: [biofuel] Methanol Does anyone know how much methanol is recoverable in total, assuming that 25% meth is used (by vol of wvo). It would also be interesting to find descriptions of methods of extraction from both the glycerine and the wash water.
