Question:
Five hundred lbmol of 48.8 mol% A and 51.2 mol% B with a relative volatility aA,B of 2.0 is separated in a batch rectifier consisting of a total condenser, a column with seven theoretical stages, and a still-pot. The reflux ratio is varied to maintain the distillate at 95 mol% A. The column operates with a vapor boilup rate of 213.5 lbmol/h. The rectification is stopped when the mole fraction of A in the still is 0.192. Determine the
(a) Rectification time and
(b) Total amount of distillate produced.
