Simulation of Simulated Moving Bed process model

Based on the single column partial differential equation model for the industry chromatographic separation, the mathematical model of the Simulated Moving Bed chromatographic separation process is established from the flow and mass conservation relations of the SMB process. Method of line is used for the numeric model computations. Simulation results show that compared with the true moving bed model, the established model takes into consideration the periodic switch at the feed inlets and outlets, hence reflects the conditions in a true SMB process.
