Abstract
There is provided a process for efficient chromatographic separation of a plurality of components from a fluid feed containing the same, which process comprises repeating a cycle comprising the step (1) of substantially shutting off the internal fluid circulation at a position of endless, or continuous, circulatory system and withdrawing a fraction enriched with a component having a strong affinity for an adsorbent upstream of the shut-off position while feeding the fluid feed downstream of the shut-off position, and the step (2) of withdrawing a plurality of fractions enriched with the remaining components while feeding a fluid desorbent and circulating the internal fluid.
