Tools for reactive distillation column design: Graphical and stage-to-stage computation methods

Abstract

Publisher Summary This chapter introduces a new set of graphical and multicomponent stage-to-stage computation methods for the design of reactive distillation columns. These design methods are based on the element mass balance approach. The methods developed are similar to those typically employed for nonreactive systems. For binary element systems, which may be ternary or higher in terms of mixture compounds, a simple reactive McCabe–Thiele method has been developed. For design of ternary element systems, which are usually quaternary or higher in terms of mixture compounds, a reactive stage-to-stage calculation method has been developed. For columns comprising reactive and nonreactive stages, the stage-to-stage procedure is used. The driving force approach of Gani and Bek–Pedersen has been extended to application in reactive separation systems. The methods have been tested in a systematic manner with several reactive systems. The chapter discusses the methyl tert-butyl ether (MTBE) reactive system. All design examples have been verified through rigorous simulations.
