[Biofuel] tirating a virgin oil
Hi, Recently I've came through problems with testing a cheap virgin oil in my test processor which every time ended up with incomplete reactions (emulsion problems). I did make the process longer (2 hours) and at higher temperature (60-63 degC) - still nothing, though by product separation is very nice. Today, I tried to titrate the oil and - to my surprise - it took 0.925ml of KOH solution. This was my first experience with titration, so I can also tell that the phenolophtalein solution turned pale (but noticable) magenta for about 15 secs (as described at JtF) after 0.925ml. After adding 1.05ml the colour got more intensive for longer time. My main question is - is it normal in case of cheap oils ? I suppose they contain (as other oils) some amount of FFAs, but so much ? Additional matter is whether I got titration right. I mean, interpreting the colours. I'm running out of ideas what could be wrong in the process, so any help is appreciated. -- cheers, Rafal Szczesniak **mir[at]diament.iit.pwr.wroc.pl Samba Team member mi***[at]samba.org +-+ *BSD, GNU/Linux and Samba http://www.samba.org +-+ ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] tirating a virgin oil
Rafal, I assume you are doing 1L test batches? Correct me if I'm wrong. Do you know the purity of the KOH you are using? I have heard of virgin oil containing some FFA. I have no experience with such oil. Your interpretation of the titration color sounds fine to me. The difference between .925 g KOH and 1.05 g KOH represents a 1 - 2 % difference in the amount of caustic/L of oil and would be insignificant compared to the approximately 15% difference in caustic needed for oil that titrates .925ml KOH and virgin oil that titrates to 0ml. Don't despair. Overcoming obstacles early on is part of the learning process. It is why one should start with small (1L) test batches.

I have heard tell of AP from the chemistry students (the naughty ones) here at work. From what I gather, the description is true, that it takes a good deal of time to precipitate out the final product making it problematic to produce in the confines of an airline flight. If it could be done on an airline (say a nice trans-atlantic flight) then the result could be bad since the velocity of detonation is about 5/6ths that of TNT. However, I'm of the opinion that it was not fesiable and the conspiricy has some merit. It seems to me that the ideal explosive on a plane would be a few rolls of Mentos and some Soda Pop...

"We all feel badly let down by Bush," the source said. "We thought we had persuaded him to take the Israel-Palestine situation seriously, but we were wrong. How can anyone have faith in a man of such low intellect?" The report comes as Parliament prepares to hold an unusual summer session, to allow members to question the government's handling of Israel's war with Hezbollah and examine whether the recent terror plot in Britain was linked to Blair's Iraq war policy. The newspaper said the reported rift between London and Washington is based on British anger over Bush's handling of the "road map" to peace between Israel and the Palestinians, which Bush agreed to just before the U.S.-led invasion of Iraq. "We have been banging on at them for three years about the need to address the Palestinian problem but they just won't engage," said a senior government source.

Re: [Biofuel] tirating a virgin oil
Dear Rafal, First of all, as long as you use cheap oil you should always be prepared to deal with much more FFA and water than it should normally contain. I think your emulsion problem occurs as a result of highly contained water. If that is the problem you should first dry the oil then process the reaction. Also if you use crude oil you should be very careful about the chemicals, such as lesitine, in the oil. So always try to use degummed oil, if you have to process crude oil. Another thing is, as you probably know, approximately 95 - 97 % of the reaction is completed in the first 35 minutes, so you do not have to wait for 2 hours. Also the alcohol boils at 65 C and the closer you get to that point, the more alcohol you will lose at the time you need it the most for the reaction. This prevents you to complete the reaction 100 %. As I mentioned above if you just watch the content of water and the other impurities in the oil you will be fine. Hopefully the information works for you. I am looking forward to hear from you soon.
