Abstract

L'invention concerne un procédé pour la mise en oeuvre d'une installation d'adsorption comportant au moins deux adsorbeurs constitués chacun d'un récipient divisé en deux chambres par un lit adsorbant régénérable pour extraire le solvant de l'air chargé de solvant que l'on fait passer à travers le lit adsorbant d'une chambre dans l'autre. Selon l'invention, on fait passer la vapeur à travers un adsorbeur retiré du circuit d'adsorption pour éliminer le solvant adsorbé par le lit adsorbant par entraînement à la vapeur en vue de la récupération ultérieure du solvant et pendant au moins une partie de l'entraînement à la vapeur, on envoie le distillat dans un second adsorbeur également retiré du circuit d'adsorption pour commencer la régénération à la vapeur du lit adsorbant dudit second adsorbeur avant de refroidir le distillat en vue de la récupération du solvant.The invention relates to a process for the implementation of an adsorption installation comprising at least two adsorbers each consisting of a container divided into two chambers by a regenerable adsorbent bed for extracting the solvent from the air loaded with solvent that one passes through the adsorbent bed from one chamber to the other. According to the invention, the vapor is passed through an adsorber withdrawn from the adsorption circuit in order to remove the solvent adsorbed by the adsorbent bed by steam entrainment for the subsequent recovery of the solvent and for at least part of the time. 'steam entrainment, the distillate is sent to a second adsorber also removed from the adsorption circuit to begin the steam regeneration of the adsorbent bed of said second adsorber before cooling the distillate for the recovery of the solvent.
