E1. You need a solution to Problem 9.D23 (batch distillation) for this problem.
The batch distillation column in Problem 9.D23 is a 6-inch diameter packed column that is packed with 5/8-inch metal Pall rings. Operate at a vapor flux that is 70% of flooding. Design for conditions at the end of the batch calculated at the bottom of the column. Estimate the viscosity as that of pure water at 100°C (0.26 cP). Find the operating time for the batch distillation with the packed column.
