We present a simple rule that, for the first time, enables exhaustive enumeration of dividing wall columns (DWCs) corresponding to any given thermally coupled distillation column-configuration. With the successive application of our rule, every partition in a DWC can be extended all the way to the top and/or to the bottom of a column without losing thermodynamic equivalence to the original thermally coupled configuration. This leads to easy-to-operate DWCs with possible control/regulation of each and every vapor split by external means. As a result, we conclude that any given DWC can be transformed into a thermodynamically equivalent form that is easy-to-operate, and hence, there always exists at least one easy-to-operate DWC for any given thermally coupled distillation. Our method of enumerating and identifying easy-to-operate DWCs for an attractive thermally coupled configuration will contribute toward process intensification by providing ways to implement efficient and low-cost multicomponent distillations. © 2017 American Institute of Chemical Engineers AIChE J, 2017

一种合成所有分隔壁塔以进行n组分分离的系统方法:第二部分

我们提出了一条简单的规则,这是第一次使穷举式的分隔壁塔(DWC)能够对应于任何给定的热耦合蒸馏塔配置。通过连续应用我们的规则,DWC中的每个分区都可以一直扩展到色谱柱的顶部和/或底部,而不会失去与原始热耦合配置等效的热力学等效性。这就导致了易于操作的DWC,并可能通过外部方式控制/调节每一个蒸汽。结果,我们得出结论,任何给定的DWC都可以转化为易于操作的热力学等效形式,因此,对于任何给定的热耦合蒸馏,始终存在至少一个易于操作的DWC。我们枚举和识别具有吸引力的热耦合配置的易于操作的DWC的方法,将通过提供实现高效且低成本多组分蒸馏的方法来促进工艺强度的提高。©2017美国化学工程师学会AIChE的Ĵ,2017年
