Abstract
A pressure swing adsorption system includes a pressure vessel, a nozzle plate coupled to the vessel and sealed with respect to the pressure vessel, a backing plate that supports the nozzle plate, and a manifold including a plenum cavity and coupled to the nozzle plate via a neck such that the plenum cavity is in fluid communication with an interior of the pressure vessel. The neck is sealed with respect to the nozzle plate via a movable sealing surface. A method is provided in which pressure from the plenum cavity assists in closing valve coupled to the manifold. A removable insert is provided to the manifold to provide a removable sealing surface against which the valve closes.
