Adsorption Properties, Mathematical Modelling, Optimization, Control and Supervision of Simulated Moving Bed (SMB) processes
Conventional batch chromatography is relatively inefficient in terms of adsorbent and solvent consumption and significant benefits can be achieved by performing separation of high-added value products, such as enantiomers produced in the pharmaceutical industry, with a simulated moving bed (SMB) process (Lehoucq et al., 2000). The SMB process allows a counter-current movement of the liquid and ...
متن کاملProteins Separation and Purification by Expanded Bed Adsorption and Simulated Moving Bed Technology
Proteins not only play an important role in biology, but also have large potential applications in pharmaceuticals and therapeutics, food processing, textiles and leather goods, detergents, and paper manufacturing. With the development of molecular biology technologies, various kinds of proteins can be prepared from upstream processes and from biological raw materials. However, there exist vari...
متن کاملOptimal 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 کاملA Hybrid Automaton Representation of Simulated Moving Bed 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. Copyright ©2002 IFAC
متن کاملInteractive multi - objective optimization for simulated moving bed processes
In this paper, efficient optimization techniques are used to solve multi-objective optimization problems arising from Simulated Moving Bed (SMB) processes. SMBs are widely used in many industrial separations of chemical products and they are very challenging from the optimization point of view. With the help of interactive multi-objective optimization, several conflicting objectives can be cons...
