A temperature swing adsorption process for removing a target component from a gaseous mixture containing water and at least one side component, said process comprising: (a) at least one adsorption step, providing a target component-loaded adsorbent and at least one waste stream depleted of the target component; (b) a desorption step, comprising heating of the loaded adsorbent to a desorption temperature and providing a first output stream containing the desorbed target component; (c) a conditioning step; (d) at least one target component-releasing releasing step bringing the solid adsorbent to a temperature lower than said desorption temperature and providing at least one second output stream containing an amount of the target component and containing water; (e) separating water from said second output stream(s) and (f) subjecting the so obtained water-depleted stream(s) to said adsorption step or to at least one of said adsorption steps.

Temperature-swing adsoroption process

A temperature swing adsorption process for removing a target component from a gaseous mixture, the process being carried out in a plurality of reactors, wherein each reactor performs: (a) adsorption of the target component providing a loaded adsorbent and a waste stream; (b) heating of the loaded adsorbent and desorption of target component, providing an output stream; (c) cooling of the adsorbent; a rinse step (a1) before the heating (b), wherein the loaded adsorbent is contacted with a rinse stream containing the target component, producing a purge stream depleted of the target component; a purge step (b1) before the cooling (c), wherein the adsorbent is contacted with the purge stream provided by another reactor while performing the rinse step (a1), thus producing an output stream containing the target component, wherein the rinse stream comprises at least a portion of the output stream provided by another reactor while performing the purge step (b1).

Temperature-swing adsorption process

A temperature swing adsorption process for removing a target component from a gaseous mixture containing at least one side component besides the target component, said process being carried out in at least one reactor performing the following steps: an adsorption step (a), wherein an input stream of said gaseous mixture is contacted with a solid adsorbent selective for said target component, producing a first waste stream depleted of the target component; a heating step (b) for regeneration of the loaded adsorbent providing a first output stream containing the target component; a cooling step (c) of the regenerated adsorbent, said process also comprising: i) a preliminary heating step (a) before said heating step (b), wherein a gaseous product containing said at least one side component is released from the adsorbent; ii) recycle of said gaseous product to a further adsorption step (a).

A temperature swing adsorption (TSA) process for removing a target component from a gaseous mixture, where the process is carried out in a plurality of reactors. Each reactor performs the following steps: an adsorption step wherein an input stream of said gaseous mixture is contacted with a solid adsorbent selective for said target component, producing a first waste stream depleted of the target component; a heating step for regeneration of the loaded adsorbent providing a first output stream containing the target component; and a cooling step of the regenerated adsorbent.
