Dear Tom ,really very good your plan to make biofuel from Waste oil .As you are near by Brazil, you can think of the flexible car as this can run both form ethanol as well as the biogas which can be very made in small scale in the farm.Go ahead with the help of several experts from here as the small scale unit of our can be good start in the South America .For the same you can better make use of several recent information , thanks to Keith hard work to make our list archives much update , as this can solve half of hard problems to do practical woks in the field of Biofuel.I believe the south America can be the leader of the Biofuel using appropriate small bio refinery.
Let us join to make this reality , with the help of this list members too as the wise peoples and all relevant informations needed are made possible here.Wishing you the best success.
Yours truely

Hi Manick,Although I am an American, I live in Uruguay. There is no access to ethanol vehicles here as yet. Diesel vehicles definitely are available though heavily taxed. Plus this fits my overall scheme for making BioD in sufficient quantities to power an electric generator, my car and ultimately my tractor. The waste heat from the generator will heat hot water for house use and it's heating system. I'm lining up waste oil suppliers so I can have about 2000 or more liters per year available. The money I hope to save doing this will be put into the organic farm on high ground just outside the city. That's it in a nutshell.Tom Irwin

Yes, after making temperature correction for water at 25-30C I get 0.785 which is very near literature value of 0.7893 for ethanol and pure enough for mixing. Could you please enlighten me why you did not opt for E85 auto which I understand is available in USA?
Tom Irwin <[EMAIL PROTECTED]> wrote:Thanks Manick,I just ran a density test. I got 0.7824g/cc vs. .7893g/cc from my CRC handbook. The original material is .7924g/cc. That's about a 10 or 12 % removal. with some slop for my measuring technique this might be good stuff. I'll try mixing it with gasolene next. Thanks all.Tom Irwin

Hello Tom,May I offer unorthodox solution? Try to measure the specific gravity and density using specific gravity bottle. If it matches sg of pure ethanol you are there for practical purposes, unless you are aiming for AR quality..
Tom Irwin <[EMAIL PROTECTED]> wrote:Hi All,I finally found a source of 3A molecular sieve. It´s been sitting in 95% ethanol overnight. How do I test the ethanol to see if I removed the 5% water? Simple mass balance? I don´t have a Karl Fisher titrator. BTW, I used the recommended 250 grams of 3A per liter of ethanol.Thanks,Tom Irwin_______________________________________________
