By means of water as an extractant, the two?feed and three?feed reactive distillation production processes of methylal are synthesized and analyzed. Effects of water on the methylal RD production is investigated. Furthermore, the thermally coupled two?feed and three?feed reactive dividing?wall columns are proposed and analyzed. Comparison of the two?feed and three?feed RD processes are conducted, and the three?feed thermally coupled reactive DWC shows an outstanding ability of energy and cost consumption. Results from this work could be helpful for further development and application of the reactive distillation or reactive dividing?wall column in the methylal production.
