Abstract
The invention disclosed is a method and apparatus for moving-bed or simulated-moving-bed continuous chromatographic separation, in which some solvent is removed from the elution liquid at a point between the two zones where fractionation takes place. The resulting product streams have higher recovery and purity than without such solvent removal.
