[Biofuel] bubble WASHING and oxidation.

Since I am not a chemist by any means, I was wondering why I should be concerned about oxidation? I could see a problem if I was trying to store the fuel perhaps,but I use up to 50 gal a week. I have only noticed oxidation being a problem in my best tequila after many months if I don't drink

Since I am not a chemist by any means, Very few of us are. So what. I was wondering why I should be concerned about oxidation? You don't know? It's been discussed a lot since you joined. See: http://www.mail-archive.com/biofuel@sustainablelists.org/msg46511.html [Biofuel] Stirring and

Re: [Biofuel] bubble WASHING and oxidation.

I'm a NewB to Biodiesel and never even considered oxidation. What would happen if you purged your mixing chamber with N2 or CO2 and used it as the bubble supply? Course you would need to keep everything sealed and/or purged from dewater to fuel tank. Just thinking out loud. Shane ---

RE: [Biofuel] bubble WASHING and oxidation.

Hi Shane, Good idea, in principle, however the energy used by the gas Co. to compress distribute your N2 or CO2 is really a waste when simple agitation washing would suffice, assuming your fuel to be washed is well made of course. Don't forget, unless you have your own water supply, energy has

Re: [Biofuel] Fw: Electronic PH meter

Howdy Kieth and Willem, the issue of the use of a pH meter as opposed to other methods for determination of the end point of a titration comes up from time to time. It seems that many believe one really needs a pH meter. I think not and here is why. Although a pH meter may be more accurate

Re: [Biofuel] Re: solar tracking devices

OK folks. For what its worth, here is another crack at it. 1 square meter panel = 1000W * .10 (split the difference between 8 and 12) = 100W 100W * $5.00/W = $500.00 per panel 100W * .30 = energy gained using tracker, based on previous reference = 30W Equivalent value of PV panel = 30W *$5.00 =

[Biofuel] Reactors - tall or short

Hi everyone, I'm in the planning stageof trying to put together my biodiesel reactor. I've heard that the taller slimmer water heaters are usually best, however, I'm a bit cramped for space would probably need to go with a shorter one. If anyone has any thoughts, comments, advice, etc, I would

[Biofuel] introduction and stirring question.

I just joined. I am a chemistry teacher, and I've decided I'm going to start making biodiesel this summer. I ran some test batches this week, and I'm going to start on my reactor today. I read in the archives an allusion to someone attempting to make a magnetic stir plate. I had the same idea

Re: [Biofuel] Fw: Electronic PH meter

I haven't done much with biodiesel yet, but I can shed some light on pH meters vs. phenolphthalien(PHTH) from a chemist's perspective. As acids become weaker, it is important to become more careful in the selection of a chemical indicator (such as PHTH), as the change in pH is much slower than it
