- Hello All, I asked some questions in my last post but didnt get any answers but Ill ask another one anyway and maybe someone will answer it. Im assuming that when the unwashed biodiesel stratifies, that pretty much all the Glycerine-methanol and soap has settled beneath the biodiesel and that can be decanted. The washing process to meet astm seems to take up a long time .. Is it feasable to distill the water-methanol mix out of the biodiesel rather than wait for it to separate and stratify?? or will trace elements of soap screw things up..?...any thoughts on this??? Marc
