Abstract

See full text

The present invention relates to a method for fractionating a feedstock into two or more fractions enriched with different components, and more particularly to a method for fractionating a feedstock into two or more fractions by a chromatographic sequential simulated moving bed (SMB) system, wherein the SMB system comprises a separation loop comprising at least 2 compartments; and wherein the method comprises a separation cycle comprising at least one feeding step, at least one circulating step and at least one eluting step; wherein the dissolved substances in the feedstock form a separation profile as they progress through the separation loop; and the separation profile is progressed more than once or less than once through the separation loop in each separation cycle; and wherein at least two flow paths are present in the separation loop during each feeding step of the separation cycle; and at least one of said flow paths is an active flow path and at least one of said flow paths is an inactive flow path.
