Re: [Biofuel] Proper intgration of Biofuels for small farms

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

[Biofuel] Glycerine Settling Time

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.

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. - Original Message - From: Thomas Kelly To: biofuel@sustainablelists.org Sent: Thursday, August 09, 2007

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.

Andres, For the sake of precise concepts, gliceryn is NOT an emulsifier. 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

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

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
