Abstract
A valve assembly (B) cycles compressed gas from a compressor (A) to a pair of molecular sieve beds (C) to perform a pressure swing adsorption gas separation cycle. Each bed includes a peripheral outer wall (20) and has a tubular member (30) extending down a central axis thereof. An extensible sleeve (26) surrounds the central tube and is in fluid communication therewith by way of an aperture (32). A fluid amplifier (F) amplifies fluid pressure from system gases, particularly the gases from the compressor, and uses the amplified pressure to expand the extensible sleeve. Particles (22) of zeolite material are inhibited from becoming fluidized and moving with fluid flows by the clamping pressure between the extensible sleeve and the peripheral wall of the bed.
