Heteroazeotrope

The simplest case of continuous heteroazeotropic distillation is the separation of a binary heterogeneous azeotropic mixture.

The other application of the heteroazeotropic distillation is the separation of a binary system (A-B) forming a homogeneous azeotrope.

The main parts of the conventional batch distillation columns are the following: - pot (include reboiler) - column - condenser to condense the top vapour - product receivers - (entrainer fed) In case of the heteroazeotropic distillation the equipment is completed with a decanter, where the two liquid phases are split.

The heteroazeotropic batch distillation was investigated by feasibility studies, rigorous simulation calculations and laboratory experiments.

Experimental result was published by Rodriguez-Donis et al.,[10] Xu and Wand,[11] Van Kaam [12] and others.
