Abstract
An improved three-bed nonimmobilized rapid pressure-swing adsorber for use in a gas separation system. The three beds are connected in parallel and actuated so that at any one time, at least one of the beds is on-line, purifying the gas stream. The sequence of operation is such that during a full cycle of operation, two of the beds will be purging for at least some of the cycle to reduce the purge gas volume flow requirements, and thus increase the efficiency of the system. When a primary adsorber bed is on-line, another bed may be depressurizing from an on-line condition to a purge condition while the third bed is being purged. At a certain time, both the off-line beds are being purged until the third bed is repressurized in preparation for going on-line. Prior to the first bed going off-line and being depressurized, the third bed is placed on-line to ensure an uninterrupted supply of process gas to the system.
