A rotary module (10) for implementing a high frequency pressure swing adsorption process includes a stator (14) having a number of function compartments opening into the stator valve faces, a rotor (11) rotatably coupled to the stator and including a number of apertures opening into the rotor valve faces, and a self-regulating clearance-type valve seal positioned between the valve faces of the stator and rotor so as to regulate the rate of gas flow between the stator and the rotor. Each valve seal includes a sealing face disposed adjacent a respective one of the rotor valve faces and is pivotable relative to the respective rotor valve face for varying the gas flow rate in accordance with the clearance distance between the sealing face and the respective rotor valve face. Each valve seal also includes a passage which communicates with one of the function compartments for varying the clearance distance in response to a pressure differential between the passage and an approaching aperture. In this way, the valve seal maintains a smooth pressure transition profile as the flow paths are switched between the function compartments. As a result, equilibrium is maintained between the adsorbent material and the mass transfer front of the gas, and the efficiency of the gas separation process is enhanced.

La présente invention concerne un module rotatif (10) permettant la mise en oeuvre d'un processus d'adsorption modulée en pression. Ce module comprend un stator (14) pourvu d'une pluralité de compartiments fonctionnels débouchant dans les façades de soupapes du stator, un rotor (11) couplé rotatif au stator et incluant une pluralité d'orifices débouchant dans les façades de soupapes du rotor, et un joint de soupape du type à reprise automatique de jeu monté entre les façades de soupapes du stator et du rotor de façon à réguler le débit de gaz entre le stator et le rotor. Chaque joint de soupape, qui présente une face étanche venant contre la face étanche correspondante des façades de soupape du rotor, est capable de rotation par rapport à la façade considérée de soupapes du rotor de façon à moduler le débit de gaz en fonction du jeu entre la face du joint et la façade de soupapes correspondante du rotor. Chaque joint de soupape comprend également un passage en communication avec l'un des compartiments fonctionnels de façon à faire varier le jeu en fonction d'un différentiel de pression entre le passage et une ouverture se rapprochant. De cette façon, le joint de soupape conserve un profil lisse de transition de pression pendant l'inversion des chemins bas entre compartiments fonctionnels. Il en résulte que l'on ne modifie pas l'équilibre entre le matériau adsorbant et le front de transfert de masse du gaz, et ce, tout en augmentant l'efficacité du processus de séparation des gaz.
