Re: [biofuel] zeolite - Digest Number 489
Hi Ed- I haven`t produced any biodiesel but I have done several experiments boiling off the water and filtering etc. and have produced a clear yellowey oil that I am sure is of some value- indeed it will burn away an its own once I get it ignited with a light yellow flame. Anyway, from a feedstock/cost point of view, trap waste has to be a good option- as the restaurant pays you to take it away! With the proper separation the food sludge can be composted, water goes to drain and the fat,oil,grease (FOG) can be recovered, assuming the water in oil can be removed at a reasonable cost. There must be a way of removing this water without high energy(cost) input.

Re: [biofuel] zeolite - Digest Number 489
Joseph Martelle wrotethese filters work because water in oil is an emulsion and thus easily separated with marine filters. Is this true? How do you take the oil out of emulsion, I have heard of de-emulsifying agents (chemicals) but they are expensive. Are there different types of emulsions - permanent emulsions, semi emulsions-what is an emulsion anyway? I collect large quantities of this type of waste from grease traps. Even the free floating oil/grease that separates out and is skimmed off carefully contains 20-30%water. (I refer to this as water in oil as opposed to oil in water) I find that the longer I let it sit, the more water will drop out after several weeks) leaving maybe 5-10% water in oil if I`m lucky., maybe it is my imagination but I think that some of the water may even be evaporating off when left to settle in an open top drum.I have thought about dripping the oil in some sort of enclosed environment onto a needle point (or something) that will shatter the droplet or indeed a mist sprayer and use an anhydrous powder to soak up any moisture that evaporates off. This would be cheap and gravity fed-but would it work? Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Please do NOT send unsubscribe messages to the list address.

Re: [biofuel] Re: small diesels and filtering fat
Thanks for comments. I already am getting paid to take away those fat balls! The problem is what to do with them- they certainly have water (but it can be as little as 10-20% if left to stand for long enough) and also quite a bit of food waste and debris. Any suggestions?

Hi, anybody ever done anything useful with greasetrap fat? I can just about get it to burn. Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html To unsubscribe, send an email to: [EMAIL PROTECTED] Your use of Yahoo! Groups is subject to http://docs.yahoo.com/info/terms/
