This paper demonstrates that a state estimator can be successfully designed and implemented in a feedback control system of reactive distillation. The work of the state estimator is to provide the state compositions that are required to be used in th

The dynamic behavior for a high-purity/high-conversion reactive distillation is investigated. The impact of disturbance magnitudes and directions on both open loop and closed loop stability of the system is studied. Excess of less volatile reactant i

The performance of a linearized dynamic model of a generic reactive distillation system has been compared with that of a rigorous nonlinear model. The effect of steady state sensitivity to different input step changes on the performance of the approx

This paper presents a comprehensive formulation of a linearized state space process model for a generic two-reactant-two-product reactive distillation system. The development of the model requires the knowledge of the desired steady state design data

This paper compares the closed-loop performance of three control structures using an approximate linear model to that when a rigorous nonlinear process model is used for a generic reactive distillation. It is shown that an approximate linear model be

The synthesis and control of a plantwide flowsheet to produce tert-amyl methyl ether (TAME) is reported. The flowsheet consists of a plug-flow reactor, one reactive distillation column, and two conventional distillation columns. The two conventional

The control of an ideal reactive distillation column is compared with that of a similar, but somewhat different, real chemical system, the production of methyl acetate. Similarities and differences are observed. Three control structures are evaluated
