Patent ID: 7763102

Claim:
A pressure swing adsorption (PSA) unit comprising: a first PSA module having a first manifold, a second manifold, and a plurality of pressure vessels extending, in a longitudinal direction of at least one of the plurality of vessels, between said first manifold and said second manifold; and a first support member attached to said first manifold or said second manifold, said first support member being configured to provide rigidity to the manifold to which it is attached, wherein said first support member extends in a direction transverse to the longitudinal direction of the at least one vessel, wherein said first support member and said manifold to which said first support member is attached comprise a composite beam that has a higher moment of inertia than a moment of inertia of the manifold to which said first support member is attached, and wherein said first support member is abutted to a surface of the manifold to which it is attached on a surface of the manifold opposite, in the longitudinal direction, of the plurality of pressure vessels.
