Hi Keith and all,
I was wondering if does anyone have any information or insight into
H.T. Odum embodied energy calculations. Are they a valid way of
comparing energy sources? Has anyone done any good work on using
them for biofuel production on a small diverse farm? I saw some
discussion of
Joe,
I took a sample from my latest batch of BD destined for my boiler (failed
QT; but very little residue dropped out). It had settled for almost 10 hrs.
That was yesterday morning. Today there is a small, but noticable, bit of
glycerine on the bottom. More settled out after the
Tom;
It makes sense. Glycerin is an emulsifier. Have you ever tried dosing
the batch again with a little methoxide? After you remove the glycerin
it doesn't take much to get the last bit of the reaction to go and
settle out the remaining glycerin. Of course this is well known
already.
Joe,

From the moment that I decided to left the reacted mixture to settle two days
I never had a batch below standards.
Is a 5,000 lt reactor and the settling tank is separated.

Joe,
For the sake of precise concepts, gliceryn is NOT an emulsifier. Emulsifiers
contains a clear lipofilic and hidrofilic zones in the molecule. Which is an
emulsifier is the partially reacted mono or di-glicerides, but in a crystal
clear liquid there are not emulsions or dispersions.

I have used the glycerine cocktail to de-grease a barrel. Is it the
caustic (KOH) that reacts with the grease?
Also:
If I do a wash test on BD from a complete reaction no mono- or di-
glycerides, but
Hello all
I was just reflecting on how the growth in consumerism here in Europe has
marched hand in hand with the rise in 'personal credit' - thus empowering
(we) the masses to participate.
I wonder if this is also happenning in China and India now.

Ooops I gues you are right technically glycerin is not an emulsifier so
I shouldn't have used that term. Thanks for correcting me. It does
however have a big effect on the ability of water and esters to turn
into an emulsion. I said that because as you know when you get glycerin
even a tiny

Andres,
Emulsifiers contains a clear lipofilic and hidrofilic zones in the
molecule.
In mono- and di- glycerides the glycerin supplies the hydrophilic zone
and the fatty acid chain(s) supply the hydrophobic (lipophilic) zones.
The -OH groups in the glycerin give it regions of charge making
I absolutely agree. I loved this movie. Know the Truth, Seek the Truth, and

You are ans experimentalist like myself. How much oil/ water and how
many drops of glycerol did it take to create the emulsion?

Come on Joe!
You're giving me more credit than I deserve. I didn't measure . the old
little of this and a little of that method. I did use a graduated pipette to
draw the glycerine out of the bottle.
If it's important I can do it again. I have plenty of tap water and quite a bit
of veg

Hi Keith,
Then if you do one-litre test batches first, especially with iffy
batches of oil,
Ops.
I took Joe's point to be: If you have to re-process it is possible to
use info from the QT to determine how much (how little) methanol you'll need
to use.
I think that both Joe
