Simultaneous Design and Control of a Ternary Reactive Distillation Column with Inert Material

Process integration means significant challenges in operating a chemical process dynamically due to its complexity. One example is the ternary reactive distillation with inert material. Based on the heuristic approach, chemical process design and process control are performed independently one after another. This may lead to infeasible solutions either in process design and control or in both. The application of simultaneous design and control, formulated as mixed‐integer dynamic optimization (MIDO) problems, increased rapidly in the last decade. Simultaneous process design and control, including control structure selection and control parameters, is devised for the challenging benchmark problem of a ternary reactive distillation with inert material. The improved process design and control is obtained by solving the MIDO problem. Process integration plays a key role in chemical process industries in terms of minimizing waste and energy demands. Simultaneous design and control is demonstrated for a complex ternary reactive distillation column with inert material. The optimization problem is formulated as mixed‐integer dynamic optimization problem. An improved process design and control is achieved by solving this issue.
