I recently "dumped" a WVO supplier because their oil has become unmanageable - my best guess is that they are using Magnesol to "filter" it, and get more mileage out of it... The titration was all over the spectrum, and yes, for those of you that would ask, all was well with the titration chemicals, and process... Test batches done at titration levels varied in result, and again, I suspected I had a bad component somewhere, but even with many test batches, only changing one component at a time to control the outcome(s), it was never anywhere near what the titration said it should be... Titration results "suddenly" went up with the change of ownership... hmmm.. So, that's my best guess, and my exp. with that sort of thing... and BTW, I have other suppliers with very dark oil and their stuff titrates and processes as it should... good luck with that, Al
FWIW, I don't eat there either... >:-| > Hi All, > I was offered a dumpster full of WVO. New owner of a diner "inherited it" from the previous owner.

I would just as soon keep it out of the food chain and make 100+ gal of biodiesel. Will the two stage acid/base method handle such WVO as this? Am I looking for trouble pumping out, and getting stuck with, 100+ gal of burnt-out oil? > > The new owner is willing to give me his WVO which is nothing like what's in the dumpster. > Advice appreciated, > Tom > Biofuel mailing list > Biofuel@sustainablelists.org > http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel > > Biofuel at Journey to Forever: > http://journeytoforever.org/biofuel.html > > Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): > http://www.mail-archive.com/biofuel@sustainablelists.org/ _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
