Summary:A cyclical swing adsorption process removes contaminants from a gaseous feed stream. The process includes passing a portion of the gaseous feed stream through one of a plurality of adsorbent bed units during an adsorption step, wherein that particular adsorbent bed unit is configured to separate one or more contaminants from the portion of the gaseous feed stream to form a product stream. The flow of the gaseous feed stream to the particular adsorbent bed unit is interrupted, and one or more contaminants are removed from the adsorbent bed unit during a subsequent swing adsorption process step. The process is repeated for a subsequent cycle. Each of the adsorbent bed units are in fluid communication with a plurality of manifolds, and one of the manifolds is in fluid communication with a pulse flow control mechanism configured to lessen pulsation within that manifold. Un procédé dadsorption modulée cyclique élimine les contaminants dun flux dalimentation gazeux. Le procédé comprend la conduction dune partie du flux dalimentation gazeux à travers une unité de lit adsorbant parmi plusieurs au cours dune étape dadsorption, laquelle unité de lit adsorbant en particulier est configurée pour séparer au moins un contaminant de la partie du flux dalimentation gazeux afin de produire un flux de produit. On interrompt ensuite lécoulement du flux dalimentation gazeux vers lunité de lit adsorbant, puis on élimine au moins un contaminant de cette dernière au cours dune étape subséquente du procédé dadsorption modulée. On répète le procédé au cours dun cycle subséquent. Chacune des unités de lit adsorbant est en communication fluidique avec plusieurs collecteurs, dont un est en communication fluidique avec un mécanisme de commande du débit pulsé configuré pour réduire la pulsation à lintérieur de lui.
