abstract
A model for predicting the steady state behavior of the simulated moving bed (SMB) is developed. SMB performance is characterized by purity, recovery, solvent consumption and productivity. The effect of switching time (rotation period), extract flowrate and section length on the SMB performance is discussed. A pilot plant for the separation of optical isomers is operated and tested with two systems: “Sandoz epoxide” and “bi-naphthol”.
