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. 假定液體持液量和待分離的體系的相對揮發(fā)度均保持不變，建立了該塔的一個(gè)簡(jiǎn)化的模型，由此得到各組分在整個(gè)塔中的分布情況。
If one component changes another component's vapor pressure, or if the volatility of a component is dependent on its percentage in the mixture, the law will fail. 如果一種組分改變另一組分的蒸氣壓，或者說(shuō)，一種組分的揮發(fā)度取決于它在混合物中的百分比，那么這一定律將歸于失敗。
