Here we analysed the possibility of improving the sustainability performance for the recovery of dichloromethane and methanol from a binary azeotropic mixture using different energy-intensified extractive distillation-based processes: side-stream extractive distillation (SSED), thermally coupled extractive distillation (TCED), and extractive dividing wall column (EDWC). The sustainability performance of the different processes was analysed based on three main factors: total annual cost (TAC), CO₂ emissions, and condition number.

通过工艺设计、控制和强化实现二氯甲烷和甲醇共沸混合物的可持续分离和回收

在这里，我们分析了使用不同的能量强化萃取蒸馏工艺（侧流萃取蒸馏 (SSED)、热耦合萃取蒸馏 (TCED)、和萃取分隔壁塔 (EDWC)。基于三个主要因素分析了不同过程的可持续性绩效：年度总成本 (TAC)、CO ₂排放量和条件数。
