G'day;
I have just completed a simple condenser for methanol recovery, however I am
still left with a question.
Do I need to bring the glycerine to a rolling boil or just bring up the heat
sufficiently to get the methanol to evaporate (148.5F/65C) not necessarily
boiling ?
That depends on the exact shape of the boiling pot/chamber and still
head, but my concentrating solar still used to start getting methanol
in the condenser coil ONLY when the glycerine was "simmering".
The question is -- how rapidly does vapor have to be produced to overcome
the rate that it condenses before reaching the downhill side of your setup.
-K
I can remember people mentioning other "equipment" besides stills for
the removal of the methanol, words I can remember include "thin film",
"evaporators", "vacumn" etc etc. Can anyone provide a few "buzz words",
or links, that I should look for if I want to do a slightly larger BioD
unit, 20 Kl/week, and do methanol recovery.
Any thoughts greatly appreciated,
Andrew Lowe
