If I make a 50 gallon batch of BD, how much glycerol can I expect to separate out of it? I am trying to figure out what size tanks I will need if I do plan to vacuum off the methanol after separation. Thanks.
Thanks for the replies. When you are draining the glycerin out of the separation tank,can you see the difference enough so you can stop draining when you get to BD or how do you guys know when to stop draining?
