Abstract

The transesterification of hexanol (HeOH) with n-butyl acetate (BuAc) has a low conversion rate and high energy consumption in reactor-separator system due to its unfavorable reaction kinetics and thermodynamic properties. The conventional reactive distillation column (CRDC) and the reactive single dividing-wall distillation column (R-SDWDC) consider the coupling between the reaction and separation operations, but their inherent structural deficiencies still prevent them from effectively reducing the irreversibility of separation operations. In this work, the recently proposed principle of co-process intensification is adopted for the process synthesis and design. Full consideration is given to process intensification of the remaining separation operations based on the non-sharp separation mode in the reaction column, resulting in a step-by-step derivation of the reactive double dividing-wall distillation column (R-DDWDC). The resultant outcomes indicate that the R-DDWDC is the optimal topological structure for implementing transesterification of HeOH with BuAc. The advantages are certainly attributed to the inclusion of the process intensification between the separation operations and its coordination with the process intensification between the reaction operation and associated separation operations involved. Although the proposed methodology is derived in terms of the transesterification of HeOH with BuAc, it has universal guiding significance for reaction systems with unfavorable kinetics and thermodynamic properties.
