<p>A multi-bed PSA pressure vessel includes a hollow tubular body 12 having at least one end plate 20 releasably secured thereto. Secured to the end plate 20 are pipes 14, 16, 18 and 24 which extend along the interior of the hollow tubular body 12. Each pipe terminates at a location along the length of the tubular body 12 different from the remaining pipes. In a preferred embodiment, a plurality of perforated spacing flanges 26, 28, 30, 32 and 34 are secured to the pipe 14, some adjacent flanges eg 28 and 30 defining between them a space for receiving adsorbing sieve material. <IMAGE></p> |
