ABSTRACT:
A multicomponent mixture is separated into its components by subjecting the multicomponent mixture to a separation means to flow therein, which means comprises a plurality of columns divided into at least three groups wherein each group of columns has the columns which are in the same number as that of the components in the multicomponent mixture and are filled with a adsorbent so that one column has an adsorbent specific to either one of the components; wherein the three groups are respectively assigned to fractionation in a fractionation zone, to purification in a purification zone and to desorption in a desorption zone; the groups of columns are switched from zone to zone; and the effluent from the columns used in the fractionation zone is sent to the columns in the purification zone which have once been used in the fractionation zone and the columns in the purification zone are then assigned, upon the switching, to desorption.
