Optimal startup operation of simulated moving bed chromatographic processes
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 the system towards the reference cycl...
متن کاملModel-based Control of a Simulated Moving Bed Chromatographic Process for the Separation of Fructose and Glucose
Chromatographic separations are an emerging technology for the separation of high value products, particularly in the area of pharmaceutics, food, and ne chemicals. The simulated moving bed (SMB) process as a continuous chromatographic separation process is an interesting alternative to conventional batch chromatography, and gained more and more impact recently. The SMB process is realized by c...
متن کاملOptimization of Ternary Simulated Moving Bed Separation by Superstructure Formulation
Simulated moving bed (SMB) chromatography has been widely studied in past and there have been various operating schemes proposed for efficient separation of binary mixtures. SMB is a promising option of separation because of its capability to achieve efficient separation even when the components differ very little in terms of affinity towards the stationary phase. However, separation of a terna...
متن کاملA hybrid automaton representation of simulated countercurrent chromatographic separation processes
Simulated Moving Bed (SMB) chromatographic separation processes show typical hybrid phenomena: Discrete state jumps and switching dynamics. The SMB principle and two modelling approaches based on hybrid automaton are presented and discussed within the context of hybrid systems theory. It is shown how these models are affected by open-loop and closed-loop control.
متن کاملSimulation of Separation of a Racemic Mixture of Ibuprofen by Supercritical Fluid Chromatography in Simulated Moving Bed
Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...
