[biofuel] WVO storage and titration
I have just found 2 sources for my wvo, university cantines, they produce quite a lot of wvo. When I collect the wvo can I put it all in one tank (after it has been filtered ofcourse)and then titrate it? (since I get like 10 kg at a time). The first sample that I have received (3 liters) has some solid fat (whiteish) at the bottom which I think is animal fat. How do I get that part in to the titration process? Do I have to heat it and then mix it? Or is it enough that it is in the same cup? Or does it not effect the titration at all? Or shoud that be used only in a 2 stage method? Thanks in advance Teoman [Non-text portions of this message have been removed] Yahoo! Groups Sponsor ~-- Yahoo!

Can the WVO be stored for longer by first filtering it to say 10 micron and then storing it in a heated tank? Why heated? Heat always accelerates microbial action. Keeping it cool or cold would be better, and airtight. The heat applied during the dewatering process will sterilize it (boiling it dry) or at least pasteurize it effectively (heating to 60 deg C for 15 minutes and settling) and if you seal it straight away it should last quite well. certainly much longer than a month. What would the temperature need to be? I assume if too hot that the oil may breakdown; so, there might be a range to aim for. It will break down anyway. Two things can happen - one, microbial decomposition, two, oxidization. Water content accelerates both, and both lead to the release of free fatty acids, not good for motors when using SVO, and beyond a certain point you can't make biodiesel out of it either, or at least not easily.

Also, keep it in the dark. Light accelerates decomposition, I understand. Edward Beggs Neoteric Biofuels Inc.

[biofuel] wvo - storage precautions
What precautions do you need to take for long term storage of wvo? Can it be stored, for example, in a large 2000 gal tank without having facility for internal heating and mixing? Does it deteriorate over time? [Non-text portions of this message have been removed] Yahoo!

Re: [biofuel] wvo - storage precautions
If i can store hydrogen the biofuel is a cinch thank you for your concerns.

Re: [biofuel] WVO storage
- Original Message - From: Bud Lois Pitts [EMAIL PROTECTED] Can anyone tell me how long WVO will store and still be usable for biodiesel and what would be the best storage conditions? Also how long will BD store before it becomes contaminate with organisms as petro diesel does? Have been experimenting with waste cotten seed oil that has been stored in 20L drums for over a month. During that time the oil has become progressively thicker and more opaque. In line with my aim to simplify the production of BD by reducing input of time energy and equipment I have been processing the oil cold straight from the drum. Result 500ml oil+ 75ml methanol containing 3 grams NaOH gives 350 ml BD + 250ml heavy white sludge. Same oil when heated to 160 deg C (probably doesn't need to go that high) and cooled back to 20 deg C gives a clear golden brown oil of lower viscosity. During the heat there was no indication that water was present. Cold processing this oil gave excellent results, two layers about 500ml BD and75ml glycerine which separated rapidly. Unless I can process the oil as it is drained from the fryers I will heat the oil before processing. Having heated the oil it can be cooled to 55 deg C and processed. Ammount of NaOH I have been using is below theoretical optimum so will try 55 deg processing with increased NaOH.

Re: [biofuel] WVO storage
How long is a piece of string? A lot depends on the amount of rubbish in the oil and the temperature. As regards biodiesel - why not use it? Biocides can help, but a couple of months at cool 18 deg C temperature should do no harm Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Please do NOT send unsubscribe messages to the list address.
