Reactive distillation has received intense attention due to the well known benefits of integrating distillation with reaction in a single unit. While there are procedures available for the synthesis of non-reactive columns and of reaction-separation systems, the design of reactive distillation columns is still a challenge. This work presents a new synthesis and design methodology for reactive distillation columns featuring both reactive and non-reactive sections. Two-feed column configurations are also addressed. The design method allows rapid and relatively simple screening of different reactive distillation column configurations. The results are also suitable for initializing more rigorous calculations. The methodology is illustrated for MTBE and ethyl formate production.
