Abstract
A device (SMB) for separation by simulated moving bed adsorption comprises a plurality of elementary zones Zin series operating in a closed loop, each of said zones comprising, between two successive fluid injection or extraction points, a unique bed Lof adsorbant solid with volume VAand a non-selective free volume V, in which the majority of the zones are ordinary elementary zones each having an identical volume VA of the same adsorbant S, and a substantially identical non-selective free volume equal to V; the device also comprises at least one particular elementary zone Z, termed the particular elementary zone, comprising a non-selective free volume Vwhich is greater than V, and a unique bed Lof adsorbant Swith volume VAwhich is less than VA, Shaving a volume adsorption capacity Cwhich is greater than that, C, of S, such that the overall adsorption capacity C×VAof Zis closer to the overall adsorption capacity C×VA of each of the ordinary elementary zones than the overall adsorption capacity of Zcalculated as if the adsorbant solid of bed Lof Zwere not the solid Sbut the solid S.
