Abstract

Système d'adsorption (300') à oscillation de pression servant à séparer les constituants d'un module (301') de mélange de gaz et d'un deuxième module adsorbant (302') accouplé au premier module adsorbant, et comprenant une première entrée de gaz servant à recevoir le mélange de gaz, au moins un lit de premier matériau adsorbant communiquant avec la première entrée de gaz afin d'adsorber un constituant de mélange gazeux depuis le mélange de gaz, ainsi qu'une première sortie de gaz communiquant avec les premiers lits adsorbants afin d'en recevoir un premier gaz. Le deuxième module adsorbant comprend une deuxième entrée de gaz accouplée à la première sortie de gaz afin de recevoir le premier gaz obtenu, au moins un deuxième lit de matériau adsorbant communiquant avec la deuxième entrée de gaz afin d'adsorber un premier constituant gazeux depuis le premier gaz obtenu et une deuxième sortie de gaz communiquant avec les deuxièmes lits adsorbants afin d'en recevoir un deuxième gaz. Le premier gaz obtenu est sensiblement exempt du constituant adsorbé du mélange gazeux et le deuxième gaz obtenu est sensiblement exempt du constituant adsorbé du premier gaz obtenu. Les modules adsorbants sont également conçus afin de transférer le premier gaz entre lesdits modules sur une pluralité de niveaux de pression discrets, de façon à conserver une uniformité de l'écoulement du gaz entre lesdits modules.
