Patent ID: 8795411

Claim:
A method for recovering a desired component from a waste gas mixture, wherein the method comprises (a) at an operating facility, introducing a waste gas comprising the desired component and one or more undesired components into an adsorber vessel containing an adsorbent material selective for the desired component, adsorbing at least a portion of the desired component in the adsorbent vessel, and withdrawing therefrom an effluent gas depleted in the desired component; (b) terminating the flow of waste gas into the adsorber vessel; and (c) recovering and concentrating the desired component by either (1) isolating the adsorber vessel, transporting the adsorber vessel to a central processing facility, withdrawing from the adsorber vessel an intermediate gas enriched in the desired component, and separating the desired component from the intermediate gas to provide a concentrated product gas further enriched in the desired component, or (2) withdrawing from the adsorber vessel an intermediate gas enriched in the desired component, compressing the intermediate gas and storing it in a pressure vessel, isolating the pressure vessel, transporting the pressure vessel to a central processing facility, withdrawing the intermediate gas from the pressure vessel, and separating the desired component from the intermediate gas to provide a concentrated product gas further enriched in the desired component; wherein the operating facility is one of a plurality of operating facilities; and further comprising adsorbing on the adsorbent material at least one other component prior to adsorbing the desired component in the adsorbent vessel in step (a), wherein the desired component is more strongly adsorbed by the adsorbent material than the other component, and wherein the adsorption of the other component is effected at the central processing facility to provide an adsorber vessel containing adsorbent material having the other component adsorbed thereon, the adsorber vessel is transported to said one of the operating facilities, and the waste gas is introduced into the adsorber vessel in step (a).
