Abstract
The present invention relates to a method of fractionating liquid mixtures or solutions, comprising the steps of subjecting a feed in the form of a liquid mixture or solution to a first chromatographic separation, thereby recovering at least a fraction (A) and a fraction (B) both containing a first component or product, subjecting a mixture or solution derived from or comprising said fraction (A) to a second chromatographic separation, thereby recovering at least a fraction (C) rich in said first component or product and subjecting a mixture or solution derived from or comprising said fraction (B) to a third chromatographic separation, thereby recovering at least a fraction (D) also rich in said first component or product, and whereby at least two fractions are recovered from the second and third chromatographic separations.
