摘要
带中间贮槽的间歇精馏塔由２个分离段及其中间的贮槽组成。假定液体持液量和待分离的体系的相对挥发度均保持不变，建立了该塔的一个简化的模型，由此得到各组分在整个塔中的分布情况。在此基础上，又考察了各个操作参数对分离效果的影响。
A batch distillation column with a middle vessel is built up from two separation sections and a vessel in between. Under the assumption of constant molar overflows and relative volatility, a simplified model is developed to study the behavior of the distillation process under consideration. The influences of various process parameters on separation are investigated.
