| 摘 要： | 介绍了在理想操作条件下，“全回流”间歇精馏二元理想混合物量纲1最小操作总时间的数值计算方法.通过举例计算，比较了在理想操作条件下，“全回流”与部分回流间歇精馏二元理想混合物的能耗，得到了“全回流”间歇精馏适合于相对挥发度小、原料中轻组分的浓度低、塔顶产品中轻组分收率要求高而浓度要求低的分离任务的结论.

| Abstract: | The numeric method of dimensionless minimum total operation time of batch distillation of a binary ideal mixture under “total reflux” and ideal operating conditions is introduced.The energy consumption of batch distillation of a binary ideal mixture under “total reflux”and ideal operating conditions is compared with partial reflux using the calculated results of examples，and the conclusion shows that the batch distillation of binary mixture under “total reflux” can be adapted to the separation process characterized by a small relative volatility,low concentration of light component in the feedstock and high yield of light component in the overhead product. |

| Keywords: | batch distillation total reflux part reflux dimensionless minimum total operation time energy consumption |
