TL;DR: In this article, a review of industrial applications of DWCs and related research activities, including column configuration, design, modelling and control issues, is presented, with an emphasis on the application of the DWC for azeotropic, extractive and reactive distillation.

TL;DR: In this paper, an in-depth review of extractive distillation is presented, where a new solvent with high boiling point, i.e. separating agent, is added to the components to be separated, so as to increase their relative volatility.
Abstract: Extractive distillation is more and more commonly applied in industry, and becomes an important separation method in chemical engineering. This paper provides an in‐depth review for extractive distillation. Separation sequence of the columns, combination with other separation processes, tray configuration and operation policy are included in process of extractive distillation. Since the solvent plays an important role in the design of extractive distillation, such conventional and novel separating agents as solid salt, liquid solvent, the combination of liquid solvent and solid salt, and ionic liquid are concerned. The prominent characteristics of extractive distillation is that one new solvent with high boiling‐point, i.e. separating agent, is added to the components to be separated, so as to increase their relative volatility. Selection of a suitable solvent is fundamental to ensure an effective and economical design. CAMD as a useful tool is applied for screening the solvents and thus reducing the expe...
