Recent progress on hybrid reactive-extractive distillation for azeotropic separation: A short review

The reactive-extractive distillation (RED) has the advantages of combining beneficial features both reaction and separation processes. Relative to conventional reactive or extractive distillation-based processes, RED is also less energy intensive as it relies on heat produced for subsequent process. Therefore, application ternary azeotropic become subject popular interest, evident by increasing number publications since 2020. This review paper first that puts together, in a chronological manner, all existing studies date, starting from initial three column (TCRED) most recent dividing wall (DW-RED), separation, so rapid progress this area summarised any gaps these easier identify future work. last part provides potential areas work, i.e. analysis sustainability RED, combination different process intensification strategies improve efficiency performance, further exploration control RED.
