The present invention relates to a simulated moving bed process, wherein at least one adsorbent is washed after binding of target compound and wherein the outlet of wash liquid from the adsorbent is subsequently passed onto another adsorbent for binding of target compound removed by the washing. In one embodiment, the method comprises binding of at least one target compound using three or more adsorbents connected in series and elution of target compound from said three adsorbents. After the binding to an adsorbent, wash liquid is passed across the 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, to which no feed has yet been added. The target compound is recovered by eluting target compound from the washed adsorbents.
