“…Figure 4 shows a section of the bifurcation diagram for constant reflux rate in the 17 stage MTBE column described in Table 4. This configuration is similar to that which was analysed by Jabobs and Krishna (1 993), Nijhuis et al (1993), Schrans et al (1996) and others. Multiple steady states exist for boilup rates of 80-82 lanoyhr if the simulation model includes rigorous energy balances for each theoretical stage but only one steady state if the results are obtained with a CMO model.…”

“…The existence of multiple steady states in the reactive distillation of MTBE has been demonstrated by simulation (Jacobs and Krishna, 1993;Nijhuis et al, 1993;Schrans et al, 1996;Sneesby et al, 1998;and others) and although conclusive experimental evidence has not yet been published, this evidence is anticipated shortly as similar investigations have already been completed to experimentally confirm the existence of multiple steady states in binary distillation (Kienle et al, 1995;Koggersbnrl et al, 1996) and azeotropic distillation .…”

Commercial process simulators (Pro/IP and Speedup-) were used to investigate multiple steady states in reactive distillation via the construction of bifirrcation diagrams (the locus of solutions obtained by varying a single continuation parameter). These results indicate that the mechanisms described by

“…In order to demonstrate the application of the framework for integrated process design and controller design of multi-element systems, the synthesis of methyl-tert-butyl-ether (MTBE) and its well-known production via reactive distillation is selected (Grosser et al, 1987;Schrans et al, 1996;Sharma and Singh, 2010). Furthermore, it is assumed in this case (since chemical reaction takes fast) that the equilibrium is achieved.…”

In this work, integrated process design and control of reactive distillation processes that involve multiple elements (more than two) is addressed through a computer-aided hierarchical decomposition-based framework. Multiple elements are encountered for reactive systems when four or more compounds (including inert compounds) are encountered. The reactive distillation design methods and tools which are similar in concept to design of binary non-reactive distillations and binary reactive distillations are used for design of multi-element reactive distillation processes, such as driving force approach. The methods that are used in this work are based on equivalent binary element concept. This concept provides the representation of a multi-element system in terms of two key elements, light key and heavy key elements. First, the reactive distillation column is designed using the equivalent binary element driving force approach. Next, through analytical, steady-state and closed-loop dynamic analysis it is verified that the control structure, disturbance rejection and energy requirement of the reactive distillation column is better than any other operation point that is not at the maximum driving force. Furthermore, it is shown that the design at the maximum driving force can be both controlled using simple controllers such as PI as well as advanced controllers such as MPC.

Systematic integrated process design and control of binary element reactive distillation processes

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.
