This paper presents a novel optimization and design strategy for simulated
moving bed (SMB) chromatographic processes in general and SMB reactors in p
articular. A suitable computationally efficient and accurate process model
is presented. The choice of the process model is motivated by a brief revie
w on modeling and simulation of SMB processes. A review on design strategie
s for SMB processes, their capabilities, and limitations is given, which is
limited to pure separation processes since no rigorous design and optimiza
tion approach for SMB reactors has been published so far. The novel optimiz
ation strategy is based on mathematical optimization, a rigorous dynamic pr
ocess model, and a detailed cost function. The desired properties of the no
vel optimization approach are derived from the limitations of the currently
known design strategies. The capabilities of the new approach are illustra
ted using two applications of the SMB chromatographic reactor. Potential sa
vings in operating cost of up to 20% and in desorbent consumption of up to
60% are identified.
