Thanks Paul, I'll try to follow that up.
Currently in Thailand, we wash the BD made from stearin with almost indecent haste. Of course, if the skin comes from near the BD/glycerol interface, we should suspect methanol evaporating from the glycerol. So is the skin on the top of the BD or really on top of the glycerol? Others participants have already raised the matter of 1) whether it is BD soluble or 2) water soluble 3) Affected by separation time, 4) Disappears in the wash. Are we sure we are all talking about the same skin???? Thanks again Paul ----- there is nothing like a few facts to muck up a perfectly good theory! : - ) Michael Allen 12/12/02 00:39:00, "rpg" <[EMAIL PROTECTED]> wrote: >Michael, >have noticed that raw biodiesel from tallow readily forms a skin as it >cools, but the same BD after washing does not. >Paul Gobert. > > >Biofuels at Journey to Forever >http://journeytoforever.org/biofuel.html >Biofuel at WebConX >http://webconx.green-trust.org/2000/biofuel/biofuel.htm >List messages are archived at the Info-Archive at NNYTech: >http://archive.nnytech.net/ >To unsubscribe from this group, send an email to: >[EMAIL PROTECTED] > > > >Your use of Yahoo!
