A (V)PSA unit for purifying a gas stream by adsorption is provided. The (V)PSA unit comprises, arranged successively in the direction of flow of the feed gas stream, a rotary-structured adsorbent wheel configured so as to drive the gas stream therethrough in an axial manner and allowing the feed gas to dry to a level corresponding to a dew point below −30 C, and an adsorber with a centripetal radial configuration, comprising a bed of particulate adsorbent.

A portable gas separator assembly utilizing carbon molecular sieve absorbents or elements to separate a compressed air stream to extract nitrogen and oxygen molecules. Components of the assembly include at least two charging towers so that one tower can be charged with compressed gas while the other of the at least two towers is purged.

Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen.

One or more techniques and/or systems are disclosed for an integrated, dual-chamber, gas separator-receiver. The integrated, dual-chamber, gas separator-receiver can comprise a first and second column, which is integrated, and plumbed together. A source gas can be input through an inlet in the first column, and a target gas, separated from the source gas, can be output through an outlet in the second column. The first column can contain agents that dry the source gas, and separate the target gas from the source gas. The source gas can then be fed into the second column, where it is stored under pressure, at least until needed by some target operation that utilizes the target gas.
