摘　　要：介绍应用PRO-II精馏多级计算程序进行间歇精馏的模拟计算。给出了拟稳态模拟计算法和严格模拟计算法。较之文献广为推荐的简捷法,其结果更准确。给出了两个工业应用实例,分别用此两方法得出了计算结果。最后,还对过渡馏分返回、持液量大小等的影响得出了对比计算的结果。Introduce multistage calculation program of PRO-II distillation is adopted for the simulation calculation of batch distillation. Quasi-steady state simulation and strict simulation calculations are described. Comparison with the simplified way recommended widely in literature is carried out, and result of these calculation more accurate. Two industrial examples applied are presented, and calculation results obtained by using the said examples respectively. Calculation contrast result is also obtained from affect of more or less amount of transit component return and liquid-held etc.
