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.

“…The efficient implementations of MPC and dynamic optimization in industrial cases were already reported for several non-linear chemical processes including hybrid systems, such as reactive separations and in particular reactive distillation (Agachi et al 2006;Nagy et al 2007;Sharma and Singh 2010;Kiss 2010;Rewagad and Kiss 2012).…”

Reactive distillation (RD) processes integrate reaction and distillation, the reactants being converted with the simultaneous separation of the products. This chapter describes the use of reactive distillation technology to produce biodiesel by esterification of free fatty acids, or trans-esterification of various oils (triglycerides). An overview of the reported experimental and simulation studies is provided, covering also the process design, dynamics and control, as well as more complex RD configurations based on dividing-wall column technology.Reactive distillation (RD) is especially attractive in systems where certain chemical and phase equilibrium conditions co-exist. The reaction and distillation take place in the same zone of a distillation column, the reactants being converted with the simultaneous separation of the products and recycle of unused reactants. As the products must be separated from reactants by distillation, this implies that the products should be lighter and/or heavier than the reactants. The ideal case is when one product is the lightest and the other product is the heaviest, with the reactants being the intermediate boiling components (Luyben and Yu 2008).

In this simulation study the operation of conventional distillation column (column with one feed and two products) was investigated with the application of AspenPlus Dynamics TM software. Control structures of the column which separate a two-component mixture were studied. The aim of our investigations was to discover dynamic and steady-state effects of heating and cooling on tray temperatures. The relationship of the tray temperatures and the purity of products were also identified. Based on the identified relationships a three level hierarchical control structure was developed. On the lowest level of the hierarchy there are the local controllers of heating and cooling. On the middle level of the control hierarchy the process variables are two tray temperatures and the output of the controllers is the set point of local controllers. On the top level of the control hierarchy the purity of the products are controlled over by manipulating the set point of the temperature controllers. This paper presents the functions of the control hierarchies and the middle level of the control hierarchy was analyzed in detail.
