Is very slow vaporspeed bad?
- Hi folks!
I modified my previous version of Johan's spiral still and fired her
up. To my surprise it makes ~95% when the power is kept low enough.
The problem is that the separation is terrible. I've collected about
1.5 liters from ~4 liters of total alcohol and there's still ethyl
acetate present. Now I consider adding a column to help separation. I
have 700mm x 40mm pipe to use. I calculated the vaporspeed for
estimated 250W power and it's only ~6.5 inches / second. I know below
20 is good, but is there lower limit as well? If not do you think
700mm column will provide good separation with that vaporspeed?
