Summary

Reactive distillation is a unit operation in which chemical reaction and distillation occur simultaneously in a single piece of equipment. The reaction can be either homogeneously or heterogeneously catalyzed. The subset of heterogeneously catalyzed reactive distillation processes are commonly referred to as catalytic distillation processes. The most common properties of reaction or separation that drive use of reactive distillation are given in this chapter. Simulation calculations for reactive distillation are based on either equilibrium stage modeling or rate-based modeling. The feasibility of reactive distillation as a process option is best explored with initial simulation of the process using modern software packages such as CHEMCAD and AspenPlus. Such simulations require significant effort to characterize the physical properties and reaction rates of the species present, and choose the appropriate model for the process design. Reactive distillation is a commercially established process intensification technology that has significant applications in the emerging biorefinery.
