Abstract : The Simulated Moving Bed Process is widely used in many sectors of the chemical, petrochemical, food and pharmaceutical industry. It lies on a chromatographic separation however its continuous character imposed a hybrid behavior, marked by the absence of steady state related to the cyclic switching of the valves and by a narrow operating domain. It results a delicate modeling and a complex and challenging control. In a first part, the manuscript offers a review on chromatography which later leads to modeling and simulation of true and simulated moving beds. Model predictive control is frequently used for multivariable processes and in particular for this type of process. After a general review of model predictive control, this latter is applied on the true and simulated moving beds with consideration of hard constraints for technical parameters of the process like flow rates and soft constraints for economical criteria such as eluent consumption
