I think it was in response to a post in this list. Either that or the
biodiesel list and I put in the wrong address on my reply.
Either way, Oops. Somebody is practicing junk science.

Remember, Boiling requires heat to make it happen, even if it is
occuring in a vacumn. The vacumn making the ethanol boil will absorb
heat from the mix. That's the process that air conditioners work
byor did you mean the heat in the condensor from the condensing
vapors?

I'm looking to purchase a digital scale for weighing out the lye
in biodiesel production. My question is, how sensitive a scale is
needed? Would a scale with 1 gram readability be fine, or do I
need a readability of .1 gram?
Your answer would be most appreciated!

Can anyone give sond tchnical data as to why azeotropic ditillation is no
longer used comercially? Will the use of molecular sieves be overtaken by
pervaporation with membranes to produce 200 proof ethanol?

As I recall, azeotropic distillation of ethanol uses benzene, or maybe hexane.
Benzene is a big problem with EPA, OSHA, etc., and probably similar groups
in other countries.
guess they missed the picture of the guy drinking his biodiesel.

Why not set up a waste heat exchanger. That would allow you to
recapture some of the heat needed for distillation to heat the next
batch.

They have made a mistake, but it is actually becoming a fairly common
sentiment in Europe that pure plant oil (SVO) is greener and less
polluting than biodiesel, that it is preferable from CO2 standpoint, and
also because no methanol or processing (energy) is needed. Also, that
