[Biofuel] Query on breaking emulsions
Hi all, Seth Macdonald here from Northern BC CANADA. I run a very small bio-diesel refinery with plans to sell/trade with local organic farmers this coming spring. This winter has been particularly harsh up here and I am having problems maintaining constant temperatures in my shop. This has led to a variety of problems. Does anyone out there have any ideas on breaking an emulsion with a large batch of fuel that will NOT separate from the wash water? I know, it should never have happened in the first place. Cross-contamination due to cooled glycerin in the processor lines is likely the culprit. Even though the product DID pass the wash test. I have tried heating and cooling, but it is taking a ridiculous amount of energy to heat 40 gallons of emulsified fuel and I can't seem to get it hot enough to make any difference. Any help on this issue will be greatly appreciated. Seth "The Dredneck" Macdonald Robson Valley Bio-fuels Dunster BC CANADA V0J 1J0 PH: 250-968-4411 -- next part -- An HTML attachment was scrubbed...

Re: [Biofuel] Query on breaking emulsions
Hello Seth. 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 ?
