A rigorous plate-to-plate calculation method for reacting distillation problems by considering plate efficiency is proposed.<BR>Although several calculation methods for reacting distillation have been presented, all assumed the ideal stage, and did not consider the significance of its effect on separation. In the proposed method, a reaction term and a plate efficiency are introduced into a plate-to-plate calculation, and this is combined with Lyster's θ method of convergence to satisfy the condition of plate-matching. This algorithm satisfactorily gave us a rigorous, rapid solution of operational problems of reacting distillation.<BR>In this paper, numerical examples are presented to show the convergence characteristics of the proposed method and demonstrate the stability of solutions to initial values.
