The continuous operation is only feasible if one increases the number of plates or uses a sequence of continuous columns. 97 for a batch distillation column operating at a constant reflux. This makes the separation feasible using the given column with the number of plates equal to six. The feasibility considerations for batch distillation are described in Chapters 4 and 5 using a shortcut method. 8. 8a, as explained, is the conventional batch distillation column with the reboiler at the bottom and the condenser at the top, which essentially performs the rectifying operation.
