Abstract

The operational difficulties arising from simultaneously performing exothermic and endothermic reactions are presented. The behavior of reactor separation recycle systems carrying the coupled reactions A = P + Q (endothermic) and B + Q = R (exothermic) was studied. Irrespective of the control structure, state multiplicity could not be removed if the intermediate component Q was recycled. Thus, the chemical reactor should be designed such the recycle of Q could be avoided without economic penalty. The theoretical findings were applied to the design and control of a plant coupling ethylbenzene dehydrogenation and nitrobenzene hydrogenation for simultaneous production of styrene and aniline. After plant design, a rigorous dynamic model was developed using AspenDynamics. A plantwide control structure was implemented and achieved large production rate changes and effectively rejected various disturbances. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montréal, Quebec, Canada 8/23-27/2009).
