摘　　要：基于ChemCAD软件,利用SHOR模块对工艺流程做初步计算,确定相关参数,并对无水哌嗪分离工艺流程进行模拟。在模拟过程中重点考察了回流比、塔板数、进料位置等参数的变化对模拟计算结果产生的影响。经过分析计算确定了最优分离参数,可以得到摩尔分数为99.55%的哌嗪及摩尔分数为99.29%的三乙烯二胺产品。间歇精馏实验表明,实验值与模拟值基本吻合。Based on ChemCAD software, preliminary calculation, determination of relevant parameters of the technological process and simulation of the separation process of the anhydrous piperazine have been conducted by using SHOR module. The effect of the reflux ratio, the number of the stage and the feed stage on simulation results are studied. Piperazine with mole fraction of 99. 55% and triethylenediamine with mole fraction of 99. 29% can be obtained by analysis and calculation. The batch distillation experiment shows that experimental values are basically consistent with the simulation values.
