Method for recovering high-value components from waste gas streams

A method for recovering a desired component from a waste gas mixture, wherein the method comprises

• (a) providing an adsorption-based recovery system at an operating facility wherein the operating facility is one of a plurality of operating facilities wherein the system is adapted to recover the desired component from a waste gas comprising the desired component and one or more undesired components, wherein the desired component is recovered and concentrated in a transportable vessel;
• (b) providing a central processing facility adapted to receive the transportable vessel, to withdraw therefrom an intermediate gas enriched in the desired component, and to separate the desired component from the intermediate gas to provide a concentrated product gas further enriched in the desired component;
• (c) introducing the waste gas into the adsorption-based recovery system at the operating facility and recovering and concentrating the desired component in the transportable vessel;
• (d) transporting the transportable vessel to the central processing facility;
• and
• (e) separating the desired component from the intermediate gas and providing the concentrated product gas further enriched in the desired component;
• wherein during the introducing step and before the transporting step are the steps of:
• (1) introducing the waste gas 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 from the adsorber vessel an effluent gas depleted in the desired component;
• (2) terminating the flow of waste gas into the adsorber vessel;
• and
• (3) isolating the adsorber vessel;
• and
• after the transporting step and before the separating step, is the step of withdrawing the intermediate gas from the adsorber vessel;
• and following said withdrawing of the intermediate gas from the adsorber vessel, is the step of pressurizing the adsorber vessel with a gas containing at least one other component, wherein the desired component is more strongly adsorbed by the adsorbent material than the other component, and further comprising the steps of isolating the adsorber vessel and transporting said adsorber vessel to one of the operating facilities for use in step (1).

• (3) an intermediate gas enriched in the desired component is withdrawn from the adsorber vessel, the intermediate gas is compressed and stored in a pressure vessel, and the pressure vessel is isolated;
• and
• (4) the pressure vessel is transported to the central processing facility, the intermediate gas is withdrawn from the pressure vessel, and the desired component is separated from the intermediate gas to provide the concentrated product gas further enriched in the desired component.
