Abstract Reactive dividing wall columns (RDWC) are a highly integrated column type. The coupling of a reactive distillation and a dividing wall column leads to complex interactions between vapor-liquid mass transfer, chemical kinetics and component split around the dividing wall. In simulation studies such interactions have been shown to lead to complex dynamics and the occurrence of multiple steady states. However, experimental investigations are still missing to verify the theoretical findings. In this work the first comprehensive experimental study of the dynamic behavior of RDWCs is presented. The reference system of enzymatic catalyzed butyl acetate transesterification with hexanol has been employed to investigate the start-up and open loop behavior under different operating conditions. Two different start-up strategies are tested and compared. The experiments demonstrate the reliable and secure start-up and stable operation of a RDWC. Additionally, a developed rigorous dynamic RDWC model is presented that considers the dynamic influence on the vapor distribution in the dividing wall section. A detailed model validation is carried out using the obtained experimental data. The comparison of simulation results and experimental values show good agreement over a wide range of operating conditions.

反应性分隔壁柱的动态过程行为和模型验证

摘要 反应隔壁塔（RDWC）是一种高度集成的塔型。反应蒸馏和分隔壁塔的耦合导致气液传质、化学动力学和围绕分隔壁的组分分裂之间的复杂相互作用。在模拟研究中，这种相互作用已被证明会导致复杂的动力学和多个稳态的发生。然而，仍然缺少实验研究来验证理论发现。在这项工作中，首次对 RDWC 的动态行为进行了全面的实验研究。已采用酶催化乙酸丁酯与己醇酯交换的参考系统研究了不同操作条件下的启动和开环行为。测试和比较了两种不同的启动策略。实验证明了 RDWC 的可靠和安全启动和稳定运行。此外，还提出了一种严格的动态 RDWC 模型，该模型考虑了对分隔壁部分中蒸汽分布的动态影响。使用获得的实验数据进行详细的模型验证。模拟结果和实验值的比较表明，在广泛的操作条件下具有良好的一致性。
