If you're not a little oily and there ain't a few stains on the floor
you can't be doing it right!

I just watched a biodiesel DVD that was made in eastern Ontario. It was
obvious that a pile of money was invested by somebody but everything
looked brand new and shiny, instead of used and oily like it should.
There were three hot water tanks in all, one for preheating, one for
reacting and one for drying. As I watched it became obvious that this
guy did not have a lot of knowledge. He had a small automotive style
cartridge filter for filtering feed stock! We have just been discussing
gravity settling on this list and why prefiltration is not needed. They
were using bubble washing and heating the fuel and bubbling air through
the fuel for drying which is a nice recipe for oxidizing. Then the guy
fires up the blender for a demo batch and with 200 ml of methoxide
frothing and spitting away with blender running he takes the lid off to
pour oil in, and this is also indoors. Yikes! They then start showing a
full size batch but completely skip over the process after filling the
pre-heating tank with what looked to be very well settled or previously
filtered oil. When he demonstrates a measuring cup of glycerin he has
decanted in the background on the sight tube you can see the reactor
doesn't even have anything in it. There is no pre wash test or anything
and he doesn't say anything about titration for that matter either. Has
anybody else seen similar crap? I wonder how much of this nonsense is
floating around out there. It makes me cringe. I have been asked twice
to be on TV and once approached to help make one of these DVD's and I am
starting to get the creeps!
