ABSTRACT:
The method of chromatographic separation comprises: a feed-withdrawal step in which, with liquid flow being permitted from the first to the third unit beds in the simulated moving bed, an eluant is fed into the first unit bed and the feed stock is fed into the third unit bed while, at the same time, part of the effluent from the first unit bed is withdrawn from the system as a fraction rich in component B and the effluent from the third unit bed is withdrawn from the system as a fraction rich in component C; a circulation stage in which, with liquid circulation being permitted through the simulated moving bed, the liquid in the simulated moving bed is moved downstream without liquid feed to or withdrawal from the simulated moving bed; and a withdrawal stage in which, with liquid flow being permitted from the second to the first unit beds, the eluant is fed to the second unit bed and the effluent from the first unit bed is withdrawn from the system as a fraction rich in component A; wherein, after the above three stages are performed, the same stages are repeated except that feed stock and eluant are fed to, and effluents are withdrawn from unit beds which exist immediately downstream of the respective corresponding unit beds.
