Patent ID: 7473368

Claim:
A device permitting the separation of at least one sought compound from a mixture containing this compound, by adsorption on a simulated moving bed comprising: at least one enclosure or column, comprising a plurality of beds of adsorbents (Ai), two consecutive beds of adsorbents being separated by at least one tray (Pi) for collection/redistribution of the principal fluid and injection/extraction of secondary process fluids, the tray comprising one or more distribution/extraction/mixing, or “DME”, panels, permitting the distribution, extraction and/or mixing of these fluids, at last one multi-way rotary valve (RV), a plurality of conduits Li linking said multi-way rotary valve to said trays Pi, for at least some of the conduits Li, means for connecting two adjacent conduits in order to permit the circulation of flushing liquid with a small or zero concentration gradient for at least 40% of the time, in which said connecting means are bypasses Li,i+ 1 joining two adjacent lines Li and Li+ 1 , which are outside said multi-way rotary valve, these bypasses Li,i+ 1 comprising sectioning means Vi,i+ 1 .
