Pressure swing adsorption (PSA) separation of a gas mixture is performed in an apparatus with a plurality of adsorbent beds. The invention provides rotary multiport distributor valves to control the timing sequence of the PSA cycle steps between the beds, with flow controls cooperating with the rotary distributor valves to control the volume rates of gas flows to and from the adsorbent beds in blowdown, purge, equalization and repressurization steps.
L'invention concerne la séparation d'un mélange de gaz par un système d'adsorption modulée en pression, effectuée dans un appareil à l'aide de plusieurs lits d'adsorption. L'invention concerne des distributeurs multiports rotatifs prévus pour commander la séquence de synchronisation des étapes du cycle d'adsorption modulée en pression, avec des commandes d'écoulement coopérant avec les distributeurs rotatifs pour commander les débits volumiques de gaz s'écoulant vers des lits d'adsorption et hors de ceux-ci dans les étapes de vidange, purge, compensation et repressurisation.
