We use a batch column with four theoretical plates to separate a binary mixture of water and methanol at 1 bar. Temperature and concentration profiles versus time are obtained for a reflux ratio equal to 10. In addition, the total moles in the still and distillate are plotted versus time. This demo shows how one can use ode15s to treat a complex system of 13 differential algebraic equations very easily. This problem is solve using Berkeley-Madonna Language in the reference indicated below. We get the same results as Ingham et al. (2000).
