Reactive distillation processes can result in an economically attractive alternative to conventional process designs, where reaction and separation are carried out in dierent processing units. Successful industrial examples include esterication (Agreda et al., 1990) and etherication (Smith, 1981) processes. Numerous additional potential applications of reactive distillation are compiled in the chapter of Sharma and Mahajani on industrial applications. Consequently, there has been a lot of interest in this type of integrated processes during recent years. Emphasis has been on steady-state modeling, on the development of new processes and on the foundations of reactive distillation column design (Podrebarac et al., 1997; Taylor and Krishna, 2000; Malone and Doherty, 2000). Still, comparably little work has been done on nonlinear dynamics and control of reactive distillation processes, although these processes can sometimes show an intricate nonlinear dynamic behavior including input as well as output multiplicities and sustained oscillations. A profound understanding of these phenomena as well as their reliable prediction is not only of scientic interest, but also a necessary prerequisite for improved process design and control of industrial processes.
