Thermal integration in a reactive dividing wall column (RDWC) can dramatically reduce energy consumption. This study, however, addresses unfavorable energy integration of the concurrent esterification of butyl, amyl, and hexyl alcohols in the RDWC. The reaction kinetics and vapor-liquid-liquid equilibrium of reactive mixtures are utilized to assess the feasibility of energy integration in a multi-partitioned RDWC. The thermal integration effect of an RDWC is elucidated by comparing its energy efficiency with that of the direct sequential configuration of a reactive distillation column followed by a non-reactive distillation column. The unfavorable thermal integration in the RDWC originates from the large internal flow to satisfy the product purities. Therefore, a single RDWC sequence showed higher energy consumption and total annual cost than the direct RD sequence for the simultaneous triple esterification.

用于同步酯化反应的反应性隔壁塔的能量整合不利

反应性分隔壁塔 (RDWC) 中的热集成可以显着降低能耗。然而，这项研究解决了 RDWC 中丁醇、戊醇和己醇同时酯化的不利能量整合。利用反应混合物的反应动力学和汽液液平衡来评估多分区 RDWC 中能量整合的可行性。RDWC 的热集成效应通过将其能量效率与反应性蒸馏塔后接非反应性蒸馏塔的直接顺序配置的能量效率进行比较来阐明。RDWC 中不利的热集成源于满足产品纯度的大内部流动。所以，
