Semicontinuous Distillation of Quintenary and N‑ary Mixtures

This work examines the feasibility of the separation of a five-component mixture using a semicontinuous distillation process. The results are used to generalize semicontinuous separation to N-component mixtures. The proposed five-component separation system, called quintenary semicontinuous separation, requires just a single distillation column with three middle vessels. In contrast, a conventional continuous distillation process would require …
