Re: [biofuel] Re: some results
mark - do you mean doing a reprocess test on the clear biodiesel that I just made? I haven't done that yet, but it still isn't all that easy to wash so maybe I'll try that. when the batch that came out clear was done, there were many variables changed, such as more drying of oil, MUCH finer filtration of oil, a bit more lye, and higher proces temp - so I have to go back and try to suss out what the variable or combination of variables was that caused the fuel to clear right away after process.

[biofuel] Re: some results
Yup, it really sounds like a typical annoying emulsification troubleshooting problem. I had the same thing with what seemed to be super nice oil (other than the clarity problem which I didn't have). Just out of curiosity, what kind of oil do they use? so I asked if you reprocessed the new clear oil just because I am interested in the following: what tests are there to tell whether soaps or poor conversion are a problem? I believe that both are frequently a factor at the same time, which is why the mistwashing works even with poor biodiesel (not a reason to use mistwashing necessarily, but a reason to figure out what's making poor biodiesel instead. ANother thought: have you tried washing any better of a batch with the wash equipment you have? If not, try and get a different source of oil just to make a batch and wash it- and see if it's the process and not the washing equipment... anyway I wanted to see if you still had poor conversion... the fact that you had a hard wash means something's still off- it;'d be good to know if it was poor conversion or if it might instead be soaps. mark --- In biofuel@yahoogroups.com, Jack Kenworthy [EMAIL PROTECTED] wrote: mark - do you mean doing a reprocess test on the clear biodiesel that I just made?
