Just Posted an article on reprocessing bad batches.

http://www.make-biodiesel.org/reprocessing/

Since this thread was opened, we've changed the appearance of the site and added several articles. I still have 6 more articles in various stages of completion pending, and I'm still open for suggestions.

I didn't think it was very clear what you are suggesting to handle "Barely Biodiesel": just mixing it into later batches a little at a time?

Wouldn't, or couldn't, you use the same procedure "as shown at the end of the "Almost ASTM" paragraph"?

I really like the site, and have picked up some great info from it.

Possible suggestion could be a write up on the waste products?
Water waste, how bad is it, what to do with it.
glycerine possibilities.

Also that one should pre plan what they are going to do with there waste before starting up their own biodiesel shop..

Aww...come on! Who is that organized!? I'm been making fuel for 3 years and I'm still not 100% sure what I am going to do with the glycerin! Nearing 250 gallons stored up now...some demeth'ed...some not...

Ha true. I have to admit I didn't plan it. I should have said, its something worth considering before going all in. Or something to think about.

Another thing, in the biodiesel quality section under 3/27 on the very last line
'My Opinion - An Exelecent test for conversion'

Is that meant to be excellent? think its a typo, or a word/slang im not familiar with.

The first option would be, to ask the question, "Can I burn it without reprocessing?" The next option would be blending. I've not seen barely biodiesel reprocessed successfully into ASTM fuel using a single recipe. If the brewer was shooting for ASTM and got barely biodiesel, then he made some pretty big mistakes. The root cause would establish the reprocess recipe. For instance if the water content of the WVO was too high, then then you reprocess one way, if you short the recipe for methanol or lye, then you reprocess another way. Problem is that beginners rarely are able to figure out the root cause of the problem.

the w-h-w test is very qualitative



By qualitative, I take it you mean quantitative. It's a definitional thing. Qualitative testing implies that it will only tell you, pass/fail or good/bad. In contrast, quantitative testing will tell you an actual number. Of course, once you know the actual number, you learn exactly how good or bad your water content is. So, quantitative trumps qualitative testing in most cases.

I say this without taking anything at all away from your point that good water testing is a make or break part of the process. Both in evaluating how wet your feedstock is, and in evaluating how dry your finished fuel is. Almost all of the experienced bio homebrewers agree that water is a big deal, and often overlooked by the newbie. Can't have too much emphasis on that IMHO.


Rick, your website continues to develop and mature. Go kick JTF but.

Finest regards,

troy

ps, I hate moving with a passion. My condolences.

Again Im not sure if this is on the site and I have missed it.. but might be important to mention material compatibility under the 'building your own reactor' sections. Things like piping, reactor, fittings, seals/gaskets, immersion heater materials..

Also materials for storage, and perhaps some stuff on engine part compatibility.

Just a thought as Ive found myself researching this on the internet quite a few times when tinkering with my processor.

Hi Rick,
Just visited your site again and noticed the drop down menu on the left (main page) is partially hidded on some selections by the HPT video. Other than that it looks good. Smile

I found a cure for this. Can you help me identify which pages are having this problem?

I'm no expert by any means. I just passed the 800 gallon mark and I am still learning.
Rick, the site looks great and is bookmarked for future reference.
Thanks for all the work you put into it as I am sure I will utilize the info.

Rick, one small suggestion. On the single stage recipe, it calls for KOH/NaOH to be mixed with methanol, and then once this is done, the methanol should be mixed with the heated oil I might suggest changing that term to "methoxide" for clarity's sake.

jowarge,

I'm reluctant to use the term 'methoxide' since we really don't use methoxide. We use NaOH or KOH dissolved in methanol. You are correct that the article can stand editing for clarity. I'll work on it this weekend.

I agree with Rick. It's well established that mixing methanol with alkali does not create "methoxide" even though most people think it does.

some might find this off topic of the last couple of posts..

yes methanol mix with a caustic is not methoxide..

but is methanol mixed with an acid?

I would call it a solution of methanol and (whatever)acid.
