Vacuum Distillation Column

bjamin

I am trying to separate alcohol from a solution under a near vacuum. I would like to achieve around 95% abv and I was wondering if a fractionating column would be necessary to do so. If so, what kind of packing should I use? Would the dimensions of the fractionating column and the number of trays/plates need to be different than a conventional column (one not under vacuum)?
Thanks in advance!
