Abstract:
1. A method of separating betaine and at least one other component from a sugar beet based fermentation solution in a chromatographic SMB separation system comprising one or more partial packed beds of a strongly acid cation exchange resin and one or more partial packed beds of a weakly acid cation exchange resin, wherein the volume of the weakly acid cation exchange resin bed(s) is 20 to 40% of the volume of the total resin bed(s) of the system, comprising passing the solution through the strongly acid cation exchange resin bed(s) to form a separation profile, which comprises a part of the separation profile enriched in betaine and at least one other component, and to provide a residual fraction, which is withdrawn, and transferring and passing said part of the separation profile enriched in betaine and at least one other component to and through the weakly acid cation exchange resin bed(s) to recover a fraction enriched in betaine and to provide a fraction enriched in at least one other component.
