Apparatus and system for swing adsorption processes

A process for removing contaminants from a gaseous feed stream with a swing adsorption process, the process comprising:

• a) performing an adsorption step, wherein the adsorption step comprises passing the gaseous feed stream through an adsorbent bed unit to remove one or more contaminants and produce a product stream;
• b) interrupting a flow of the gaseous feed stream;
• c) performing a heating step, wherein the heating step comprises passing a heating stream through the adsorbent bed unit to remove the one or more contaminants from the adsorbent bed unit;
• d) performing a cooling step, wherein the cooling step comprises lessening a temperature of an adsorbent material in the adsorbent bed unit by passing a cooling stream through the adsorbent bed unit;
• e) repeating the steps a) to d) for at least one additional cycle in the swing adsorption process;
• and
• f) wherein the swing adsorption process dampens one or more of temperature, compositional, and pressure pulses associated with transition of different streams through the adsorbent bed unit between steps in the swing adsorption process.
