I was wondering how much methanol you guys are recovering from your BD(only - no glycerin) before transfer to the settling tank to let the soap drop? I'm trying to get a feel for how much of the excess methanol is in the BD vs the glycerin.
Please state how much methanol you use to process(%), the purity of the recovered methanol,the quantity of methanol recovered, and the amount of BD it's recovered from.
About 5 to 6 liters for a 40 gallon batch. I use 22% to process and usually recover at about 96% purity. Mine has been pretty consistent for the last few years. I get much more from the glycerin later.
