Description:
The reactive dividing wall column (RDWC) combines a reactor and a dividing wall column (DWC) in a single column shell. Lately, various reaction systems have been proposed for the RDWC. However, only little general knowledge has been published on the RDWC so far. In this article, the fundamental mechanisms of the RDWC are analyzed and a profound process understanding is deduced based on fundamental aspects of reactive distillation and the DWC. We systematically derive fields of application and insights into the key factors for an energy efficient operation. Moreover, we propose a semi-shortcut method to derive the minimum vapor demand of the RDWC and explain its energy saving mechanism. Thereby, process engineers can evaluate already during the process synthesis whether the RDWC is a promising option. Furthermore, they can quantify the energy savings quickly and get an understanding of the key factors for an energy efficient column design and operation.
