Tear-Off Points of the Reversible Distillation Trajectories

Condition in Tear-Off Points of the Reversible Distillation Trajectories 

Let s examine the tear-off points of the trajectories of reversible distillation from the boundary elements of the concentration simplex (Fig. 4.9). These points are points of branching one branch of the trajectory is being torn off from the boundary element and goes inside the concentration simplex, and the second branch stays inside the boundary element. Conditions [Eqs. (4.11) or (4.13)] should be 

The location of reversible distillation trajectories in the concentration simplex at sharp separation may be presented in the following brief form
