Al,
I spent a few hours monkeying around with this stuff. I succeeded in
making soap.
A couple of years ago I split the glyc. mix ----> methanol recovery. I
blended the FFAs that split out with BD to fuel my "oil-fired" heating
system. I can't help but think that somebody dumped FFAs into the dumpster.
A sample from the top titrated 19; deeper titrated 24!!! The FFAs split
from the glyc mix titrate 33. Maybe they split the glyc in order to recover
the methanol, and had no use for the FFAs.
The good news: This stuff burns nicely in a friend's waste oil heater.
A 100+ gal will help heat his shop next winter.
Thanks for the good advice,
Tom
