A new plate-to-plate calculation procedure for extractive distillation is proposed, the characteristics of which are the following three points. First, when the liquid composition in the enriching section becomes negative in the course of trial calculations, the composition is set at a small positive value. Second, the idea is introduced of solvent feed plate matching instead of conventional feed plate matching. Third, the θ-Z method of convergence is further modified by using the new parameter Zp. The merits of the present method are as follows; l) solutions obtained satisfy the rule of degrees of freedom for an extractive distillation column. 2) it is usable for any non-ideal system. 3) no experience in distillation calculation is required to assume initial values. 4) no special calculation for very small amounts of components is necessary. 5) composition profile obtained here gives a strict solution for the system.
