I do 5% prewash for my bd reactions, which means the Glycerol has 5% water in it.
If i wanna recover the methnaol fromt he glycerol (5% water in there). What shall i do? temperature control? or?
I don't wanna recover the methanol with very low purity =(, anyway to separate out the water?
keep the pot temp low enough to recover nice and slow. from what I have read, you will still end up with around 85% purity. Good enough to mix 50/50
how low temperature shall i go?
also for Dewater wvo..what temperature is good?
My pot temp can't really get above 180F, and I pull +-90% pure methanol from glycerin that has the 5% prewash in it. So that's one point to start with.
Are your reclaiming results from using a basic pot still or reflux and are you mixing the glycerin while reclaiming
It does as some amount of reflux to it since there is a 3' vertical section between the pot and the start of the condenser so the condenser can have a downhill pitch to the collection tank.
But not marbles, or steel wool, and any packing material, just an insulated 3' vertical steel pipe.
Here's a pic:
With the pot still are you mixing the glycerin at all abd if so how?, and whats your heat source electric?
Its recirculated through the blue pump, and it has a 6500 watt element inline after the pump. The element is only running on 110V though, so it only puts off 1625 watts for a low watt density.
THANKS RYAN P.
FOR YOUR HELP AND ANSWERS....
its so simple to add a relux column I don't know why you wouldn't do it. We don't prewash but we consistently get 99% pure methanol from ours. Matter of fact we brewed a 70 gallon batch the other day from all recovered methanol and it turned out fine
