A general approach for the conceptual design of counter-current reactive separations

This paper is on a number of general aspects in the preliminary design of reactive separations. It provides a method for easy identification of reaction processes that can be improved by application of reactive separation. The method is based on analyzing chemical reactions by making a distinction between intensive and extensive concentration requirements for the involved chemical substances. Conflicting concentration requirements are indicators for a potentially attractive application of reactive separation. Here, the focus is mainly on improving the performance of the reaction process.Guidelines are given for the selection of a suitable separation technology on the basis of the intensive and extensive concentration assessment, together with a checklist on various practical issues. Further, a method for conceptual process design of a multi-stage counter-current reactive separation process is given, which is guided by the extraction factors of all relevant reaction ingredients. Thus, the technical feasibility of such a reactive separation process can be assessed in an early stage of the development. The resulting process concept is a good starting point for more detailed process development work.

Synthesis and Analysis of Reactive Dividing-Wall Distillation for Methylal Production

By means of water as an extractant, the two-feed and three-feed reactive distillation production processes of methylal are synthesized and analyzed. The effects of water on the methylal reactive distillation (RD) production is investigated. Thermally coupled two-feed and three-feed reactive dividing-wall columns are proposed and analyzed. The two-feed and three-feed RD processes are compared. The three-feed thermally coupled reactive dividing-wall column (DWC) exhibits an outstanding ability of energy and cost savings. Results from this work could be helpful for further development and application of RD or reactive DWC in methylal production.
