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!
