Summary

Dividing-wall column (DWC) is nowadays applied mainly for the separation of mixtures consisting of three or more components, although novel applications to reactive, extractive, and azeotropic distillation were also reported. This chapter provides a comprehensive review of industrial DWC applications, providing referenced details about the companies currently using DWC technology, equipment constructors, process description and process flowsheets whenever available. Two case studies illustrate the application of reactive DWC to the synthesis of dimethyl ether (DME), and the use of azeotropic and extractive DWC to bioethanol dehydration processes.
