ABSTRACT:
A method of separating chemical components in a simulated-moving-bed type continuous separator comprising a series of plural packed beds filled with adsorbent for selectively adsorbing a specific component in a crude solution, in which the packed beds are divided into three zones, and the functions assigned to the respective packed beds are successively shifted to the downstream side of the flow by the quantity of one bed by means of switching means such as a channel switching control valve comprising a stationary disc and a rotary disc rotatable thereon, thereby extracting a product solution containing a high percentage of the specific component.
