Abstract
A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.
Claims18
A method for removing contaminants from a feed stream, the method comprising:
- a) performing one or more adsorption steps using a process unit comprised of a plurality of adsorbent bed units, wherein each of the one or more adsorption steps comprises:
- passing a gaseous feed stream through at least one of the plurality of adsorbent bed units comprising a self-supporting structure disposed in an interior region of a housing of the adsorbent bed unit to remove one or more contaminants from the gaseous feed stream, wherein the self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure, wherein the self-supporting structure is an open-celled structure configured to provide one or more defined channels for fluid flow paths through the self-supporting structure;
- b) performing one or more regeneration steps, wherein each of the one or more regeneration steps comprise conducting away at least a portion of the one or more contaminants from the at least one of the plurality of adsorbent bed units in a contaminant output stream;
- and
- c) repeating the steps a) to b) for at least one additional cycle.
