摘　　要：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。A shortcut design using the Fenske Underwood Gilliland(FUG) equations of continuous distillation design is developed based on the reasonable approximation that the batch distillation column can be considered as a continuous distillation column with changing feed The method is a powerful and computationally fast tool that can be used in batch vacuum distillation process design
