Title (EN) A TEMPERATURE-SWING ADSORPTION PROCESS
(FR) PROCÉDÉ D'ADSORPTION À TEMPÉRATURE ALTERNÉE
Abstract:
(EN) A temperature swing adsorption process for removing a target component from a gaseous mixture containing at least one side component besides the target component, said process being carried out in at least one reactor (101) performing the following steps: an adsorption step (a), wherein an input stream (115) of said gaseous mixture is contacted with a solid adsorbent selective for said target component, producing a first waste stream (112) depleted of the target component; a heating step (b) for regeneration of the loaded adsorbent providing a first output stream (114) containing the target component; a cooling step (c) of the regenerated adsorbent, said process also comprising: i) a preliminary heating step (a2) before said heating step (b), wherein a gaseous product (113) containing said at least one side component is released from the adsorbent; ii) recycle of said gaseous product (113) to a further adsorption step (a).
(FR) L'invention concerne un procédé d'adsorption à température alternée, destiné à éliminer un composant cible d'un mélange gazeux contenant au moins un composant complémentaire en plus du composant cible, ledit procédé étant réalisé dans au moins un réacteur (101) réalisant les étapes suivantes : une étape d'adsorption (a), pendant laquelle un flux d'entrée (115) dudit mélange gazeux entre en contact avec un adsorbant solide sélectif pour ledit composant cible, produisant un premier flux résiduel (112) appauvri du composant cible ; une étape de chauffage (b) pour la régénération de l'adsorbant chargé, fournissant un premier flux de sortie (114) contenant le composant cible ; une étape de refroidissement (c) de l'adsorbant régénéré, ledit procédé comprenant également : i) une étape de chauffage préliminaire (a2) avant ladite étape de chauffage (b), pendant laquelle un produit gazeux (113) contenant ledit au moins un composant complémentaire est libéré de l'adsorbant ; ii) le recyclage dudit produit gazeux (113) vers une autre étape d'adsorption (a).
