对间歇真空精馏过程的近似处理，将一个间歇真空精馏过程看作是一个改变进料组成的拟稳态连续过程，从而用于连续过程设计的Ｆｅｎｓｋｅ－Ｕｎｄｅｒｗｏｏｄ－Ｇｉｌｉｌａｎｄ方程被应用到间歇真空精馏过程的设计计算。该简捷设计法对组份较多且未知的复杂体系的间歇真空精馏过程的初步设计是适宜的。
The approximate treatment of an intermittent vacuum distillation process considers an intermittent vacuum distillation process as a quasi-steady state continuous process that changes the composition of the feedstock so that the Fenske-Underwood-Gililand equation for continuous process design is applied to intermittent vacuum Design and calculation of distillation process. The simple design method is suitable for the preliminary design of the batch vacuum distillation process of complex system with more components and unknown.
