Title (EN) METHOD AND APPARATUS FOR THE SEPARATION OF ONE OR MORE AGENTS
(FR) PROCEDE ET APPAREIL POUR LA SEPARATION D'UN OU DE PLUSIEURS AGENTS
Abstract:
(EN) Method and apparatus for separating one or more agents, specially solvents, from gases. The agent or the agents are adsorbed by an adsorbent and thereafter desorbed and separated in a condenser (18). The regeneration of the adsorbent includes two steps. In the first step the agent or the agents are separated from a part of the adsorbent by means of heating. In this way the concentration of the agent or the agents is increased in those parts of the adsorbent which are closest to the condenser. In a second step the remaining parts of the adsorbent are regenerated.
(FR) Procédé et appareil permettant de séparer dans des gaz un ou plusieurs agents, notamment des solvants. L'agent ou les agents sont adsorbés par un adsorbant et ensuite désorbés et séparés dans un condenseur (18). La régénération de l'adsorbant s'effectue par deux étapes dont la première comprend la séparation de l'agent ou des agents d'une partie de l'adsorbant par caléfaction, ce qui accroît la concentration de l'agent ou des agents dans les parties de l'adsorbant qui sont les plus rapprochées du condenseur. La deuxième étape comprend la régénération des parties de l'adsorbant qui restent.
