A pressure swing adsorption (PSA) system including a first group of PSA modules having a plurality of first PSA modules, and a second group of PSA modules having a plurality of second PSA modules. The system includes a feed gas manifold, a product manifold, and a waste manifold connected to the first PSA modules and the second PSA modules. Each first PSA module operates on a first PSA cycle in synchronization with the other first PSA modules, and each second PSA module operates on a second PSA cycle in synchronization with the other second PSA modules. The first PSA cycle is offset from the second PSA cycle. The PSA modules include a plurality of pressurized adsorbent chambers, an inlet manifold, and an outlet manifold. A rigid structure is provided that connects the inlet manifold to the outlet manifold, and structurally joins the inlet and outlet manifolds to the adsorbent chambers.

A method for reducing shock during a flow of fluid between a higher pressure vessel and a lower pressure vessel. The method includes the steps of providing a conduit between the higher pressure vessel and the lower pressure vessel, and minimizing a rate of pressure change within the second vessel caused by the flow of fluid along the conduit from the higher pressure vessel. The minimizing step includes controlling a rate of flow of fluid between the first vessel and the second vessel over a predetermined duration.
