Abstract
A chromatographic separation process employing fewer beds packed with an adsorbent, while enabling separation of feedstock fluid, containing a plurality of components which have different degrees of affinity for the adsorbent, into constituent fractions which are withdrawn separately. According to at least one preferred embodiment, a step of supplying feedstock fluid to the simplified separation apparatus is preceded and followed by a step of circulating the fluid through the apparatus, a cycle of supply-desorbing-circulation being carried out repeatedly.
