Abstract
The principles concerning the evolution of pinch-point zones with variation of the vapor-liquid ratio in the stripping section of a multicomponent dis tillation column with an infinite number of stages, which are similar to th ose of the pinch-point zones in the rectifying section published in a prece ding paper, are given in this work. Based on these new findings, a new meth od for calculating the minimum reflux ratio of multicomponent continuous di stillation can be developed.
