Layered manifold pressure swing adsorption device and method

A rotary adsorption apparatus, comprising at least one module which includes:

• a plurality of adsorber elements arranged in at least one adsorber set;
• a first stator defining plural fluid inlet ports;
• a first manifold for receiving a feed fluid and being intermittently fluidly coupled through the fluid inlet ports to first ends of the adsorber elements in the at least one adsorber set;
• a second stator comprising pressure swing absorption cycle sectors, each sector being defined by a light product delivery port, light reflux withdrawal ports, and light reflux return ports;
• and
• a second manifold intermittently fluidly coupled to first ends of the absorber elements in the at least one adsorber set for receiving an exhaust fluid from the first end of the adsorber elements.

A rotary adsorption device, comprising:

• a stator defining plural fluid ports;
• a plurality of adsorber elements having first and second ends, the adsorber elements being operably coupled to a rotor capable of rotation relative to the stator for rotating ends of the adsorber elements adjacent the fluid ports, at least a portion of the adsorber elements having reinforcing material adjacent the first end, the second end or both, and further with such elements directly fluidly coupling to the fluid ports;
• a first annular manifold for receiving a feed fluid and being intermittently fluidly coupled through the fluid ports to first ends of the adsorber elements;
• and
• a second annular manifold intermittently fluidly coupled to first ends of the absorber elements for receiving an exhaust fluid from the first end of the adsorber elements through plural exhaust ports defined by the stator and through a fluid conduit penetrating through the first manifold.

A rotary adsorption device for performing plural pressure swing adsorption cycles per revolution, including a module comprising:

• a first stator having a first valve face and defining plural function ports;
• a second stator having a first valve face and defining plural function ports;
• plural adsorber elements positioned between the first stator and the second stator, the adsorber elements rotated by a rotor relative to the first and second stators;
• a first manifold for delivering a feed fluid to first ends of the adsorber elements through the function ports defined by the first stator, the feed fluid undergoing pressure swing adsorption in the adsorber elements whereby a portion of a light fluid exiting a second end of a first adsorber element in a first adsorber set is delivered through a product port, a second portion of a light fluid is delivered as a first light reflux portion through a first light reflux port fluidly coupled to a first adsorber element in a third adsorber set lagging the first adsorber set, a third portion of a light fluid is delivered as a second light reflux portion to a buffer chamber, a fourth portion of a light fluid is withdrawn as a third light reflux portion through a third light reflux port fluidly coupled to a first adsorber element in a leading second adsorbcr set;
• and
• whereby a portion of a light fluid delivered by a last adsorber element in a third adsorber set is delivered through a third light reflux port to a second end of the first adsorber element in the first adsorber set, a portion of a light fluid delivered by the last adsorber element of a third adsorber set is delivered from a buffer through a second light reflux port to a second end of the first adsorber element in the first adsorber set, and a portion of a fluid delivered by a last adsorber element in a second adsorber set delivers a first light reflux portion through a first light reflux return port to a second end of the first adsorber element in the first subset.
