6 Simulated Moving Bed (SMB) processes are widely used in sugar, petrochemical, 7 and pharmaceutical industries. However, systematic optimization of SMB, especially 8 finding the optimal zone configuration including the standard and modified nonstan-9 dard configurations, is still a challenging problem. This paper proposes a simultane-10 ous, fully(More)
SMB represents one of the widely established periodic adsorption processes and its periodic and nonlinear dynamics presents a significant challenge to the formulation and solution of the optimal startup issue. A multistage startup concept allowing to adjust operating conditions stage-wise is proposed. The startup problem is then formulated aiming at driving(More)
A new improvement based on outlet fractionation and feedback has been developed for simulated moving bed (SMB) chromatography. In this contribution, this fractionation and feedback SMB (FF-SMB) concept is extended to the general scenario which integrates a simultaneous fractionation of both outlet streams. A model-based optimization approach, previously(More)
