In this work, integrated process design and control of reactive distillation processes is considered through a computer-aided framework. First, a set of simple design methods for reactive distillation column that are similar in concept to non-reactive distillation design methods are extended to designcontrol of reactive distillation columns. These methods are based on the element concept where the reacting system of compounds is represented as elements. When only two elements are needed to represent the reacting system of more than two compounds, a binary element system is identified. It is shown that the same design-control principles that apply to a non-reacting binary system of compounds are also valid for a reactive binary system of elements for distillation columns. Application of this framework shows that designing the reactive distillation process at the maximum driving force results in a feasible and reliable design of the process as well as the controller structure.

“…As seen, although our system does not have the high yield of the reactive distillation processes (above 98%), our system does not require the high operating pressures of the other processes [9,11,12] nor does it use a reflux system for the top products. While complete separation of unreacted benzene from the cumene formed is not possible in one pass, additional testing and design optimization should improve the separation results.…”

“…While these systems still require cumene be separated from the reaction by-products, they contain an energy efficient distillation step of separating unreacted benzene from the products. However, these later technologies require the use of high pressures in the column to operate [9,11].…”

A novel reactor design has been completed and tested for catalytic separation and production of cumene. Use of a reactive separation column packed with a solid acid catalyst where simultaneous reaction and partial separation occur during cumene production allows separation of unreacted excess benzene from other products as they form. This high yielding system allows for one step processing of cumene, with reduced need for product purification. Beta catalysts produced promising results, including cumene selectivity for catalytic separation reactions starting at 85% and cumene reaction yield up to 30% at a reaction temperature of 115°C. Simultaneously, up to 76% of unreacted benzene was separated from the products.

“…9 In recent years, the non-equilibrium model, also called rate-based model, has been developed for reactive distillation column to describe the mass transfer between vapor and liquid phase using the Maxwell-Stefan equations. 10 Always, the two phase non-equilibrium model is used for the prediction of the catalytic distillation, which treats the solid catalyst as a pseudo-liquid phase for the reaction in the catalyst. Also a more complex three-phase model 11 have been developed in some contributions in recent years to rigorously describe the reaction kinetics and mass transfer rate between the liquid and the solid catalytic phase in the catalytic distillation.…”
