[ We claim:] [1.] A method for producing an enriched fluid having an increased concentration of a first fluid from a stream containing the first fluid and at least one second fluid comprising the steps of:(a) the step of introducing the stream into a vessel containing a member for adsorbing the at least one second fluid:(b) the step of pressurizing the vessel for a time sufficient for the member to adsorb at least a portion of the second fluid to produce the enriched fluid;(c) the step of passing the enriched fluid to a pressurizable container to pressurize the pressurizable container; and,(d) the step of driving a member by the pressure in the pressurizable container to commence a purging cycle of the vessel when the pressurizable container reaches a preset pressure.
