摘　　要：完善了采用恒回流比操作方法 ,在理想操作条件下间歇精馏二元理想混合物时 ,最小回流比的计算方法 .分析了采用恒回流比操作方法间歇精馏二元理想混合物 ,在馏出液中轻组分的收率和平均浓度要求均高时 。It is derived that the varying manner of instantaneous constant composition region with batch distillation of a binary ideal mixture under constant reflux ratio and ideal operating condition is determined with the numeric of f(xF) [Eq. (15)] by setting up the function f(z) [Eq. (12)], and its algorithm of minimum reflux ratio can be improved. This paper analyzed the cause leading to high energy consumption of batch distillation under constant reflux ratio to meet the demand for a high light distillate composition and high average concentration of light component in the overhead product as compared to the case of operation with a constant distillate composition.
