Abstract:
A method for producing an enriched fluid stream having an increased concentration of a fluid from a fluid stream containing the first fluid and at least one second fluid comprising the steps of:(a) the step of introducing the fluid stream into a vessel which contains 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 at least one second fluid to produce a first enriched fluid stream having an increased concentration of the first fluid;(c) the step of venting the first enriched fluid at a first flow rate from the vessel through a mechanical venting valve;(d) the step of using a portion of the first enriched fluid vented from the vessel to pressurize a pressurizable storage container; and,(e) the step of introducing enriched fluid stored in the pressurizable storage container into the vessel to purge the vessel.
