Re: [Biofuel] Query on breaking emulsions
Thank you for the info Jan. As far as I know the excess methanol has already been evaporated as the batch was heated (probably excessively) outside the shop in a barrel over a three burner stove! Glycerin layer has also been removed. I'm thinking this batch did not completely react.Perhaps incorrect titration. Thanks very much for the tip on using weakly acidified water.

I think that the emulsion problem is caused by another issue that just the temperature itself. Any BD emulsion will break with the help of weakly acified water, preferably by sulphuric acid. Salty water (NaCl) is also an option. This will work assuming that you can have 20oC and that you have a reasonably good reaction of the BD. Have you evaporated the excess methanol ?

Re: [Biofuel] Query on breaking emulsions
Thanks for the tips Keith. the Journey to Forever website has revolutionized my family's life! Everything I have learned thus far about Bio-Diesel has been learned from going to your site and hands on experience. I've got a long way to go, but my community is now addicted to the concept of running on renewable energies! Thanks to all who have worked to research and develop the future of energy in our society. I'll send some photos etc. of my facility when it is finished. Another concept I am about to explore is using the biodiesel in my hydronic heating system thereby drying it while heating the floor of my shop.I installed an infloor pex pipe system in a concrete slab in the fall and I'm about to hook it up as the final stage in the processor. Once the fuel has circulated through the floor and had ample time to return to the reservoir and dry, it would be siphoned off as fuel, making room for the next batch that needs to be dried to take it's place. Only washed bio-diesel would be used for this. Are there any problems inherent with heating bio-diesel to 140 degrees?

Re: [Biofuel] Query on breaking emulsions
You are welcome. But have you analyzed the batch with the methanol test as initiated by undersigned ? That will give you useful information on the state of the batch.

Re: [Biofuel] Query on breaking emulsions
Biodiesel is not as chemically stable as gas oil, or water for heating purposes. High temperatures may cause the biodiesel to crack and form solids, so filtering is necessary to keep the circulation running. And the biodiesel will in each case loose quality in connection to heating. The higher degree of unsaturation, the greater the quality loss.But the process can be buffered by the use of anti-oxidants, preferably the BHT based. - Original Message - From: Seth Macdonald [EMAIL PROTECTED] To: sustainablelorgbiofuel@sustainablelists.org Sent: Tuesday, February 22, 2011 8:16 PM Subject: Re: [Biofuel] Query on breaking emulsions Thanks for the tips Keith. the Journey to Forever website has revolutionized my family's life!
