The invention provides a process for the regeneration of at least one adsorbent bed, comprising at least the steps of: (a) contacting a first adsorbent bed (B1) with a gaseous stream (10) such that at least a portion of adsorbed species in said first adsorbent bed (B1) are released; (b) cooling a second adsorbent bed (B2); wherein a bypass (20) is provided around the second adsorbent bed (B2) and the gaseous stream (10), before contact with the first adsorbent bed (B1), is directed to at least one of (i) the second adsorbent bed (B2), and (ii) the bypass (20) around the second adsorbent bed (B2), wherein the proportion of gaseous stream (10) flowing though the bypass (20) is controlled.

L'invention porte sur un procédé de régénération d'au moins un lit d'adsorbant. Ce procédé consiste au moins à : (a) mettre en contact un premier lit d'adsorbant (B1) avec un courant gazeux (10) de telle sorte qu'au moins une partie des espèces adsorbées dans ledit premier lit d'adsorbant (B1) soient libérées ; (b) refroidir un second lit d'adsorbant (B2), une dérivation (20) étant disposée autour du second lit d'adsorbant (B2) et le courant gazeux (10), avant contact avec le premier lit d'adsorbant (B1), étant dirigé vers au moins l'un (i) du second lit d'adsorbant (B2) et (ii) de la dérivation (20) autour du second lit d'adsorbant (B2), la proportion du courant gazeux (10) s'écoulant dans la dérivation (20) étant contrôlée.
