Abstract:
1. A method of separating at least one target compound from a feed, which method is a simulated moving bed process, said method comprising the steps of: washing at least one adsorbent after binding of the target compound; subsequently passing the outlet of wash liquid from said adsorbent onto another adsorbent for binding of the target compound removed by said washing; and continuously binding at least one target compound to one or more of three or more adsorbents which are connected in series and discrete elution of target compound from said three adsorbents; wherein after the binding, wash liquid is passed across each adsorbent to recover desorbed and/or unbound target compound, and the outlet of such wash liquid is directed to the adsorbent after the next in the series, wherein said target compound is recovered by eluting target compound from the washed adsorbents.
