简单蒸馏与平衡蒸馏比较的一种定性分析方法

摘要

简单蒸馏和平衡蒸馏是蒸馏操作的两种方法，用定量的计算来进行这两种蒸馏方法的比较很繁琐，而将t—x（y）相图应用在两者的定性分析比较中，则可以很直观地描述出各过程。本文通过具体的实例进行分析，从而得知，在相同条件下，简单蒸馏总是优于平衡蒸馏。%Simple distillation and equilibrium distillation were two methods of distillation operations. Quantitative cal- culation for this comparison of two distillation methods was cumbersome. But applying the phase diagram t -x （y）in both in the comparison of qualitative analysis, description was very intuitive to processe. From analysis of specific instances, it showed that under the same conditions, simple distillation was always better than equilibrium distillation.
