摘要： The present invention relates to a chromatographic separation process for fractionating betaine-containing solutions by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The process provides improved separation capacity and separation efficiency without affecting the yield or purity of betaine or other products. The process can especially be applied to sequential SMB separation systems.

摘要： A process for the separation of a xylose-containing, lignosulphonate-containing Ca-sulfite spent liquor is provided. The process comprises a first step of : (A) chromatographic separation of the Ca- or Mg-sulfite spent liquor using a single pass through a batch- type long resin bed chromatography column having a strong acid cation exchange resin as a separation medium. The ratio of the bed length: mean resin bead diameter of the column is 10,000- 40,000. This step yields •a first xylose-rich fraction having a xylose content 50- 70 wt. % based on dry solids and • a lignosulphonate-rich fraction. The process further comprises a step of : (B) crystallizing xylose from the first xylose rich fraction by using a crystallization method comprising (i) boiling crystallization; (ii) cooling crystallization or (iii) a combination of (i) and (ii) to obtain a first batch of crystalline xylose and a first xylose run-off. The process provides a simplification of existing methods, and at the same time allows advantages such as improved xylose yield and improved xylose purity.
