Apparatus and Systems Having Compact Configuration Multiple Swing Adsorption Beds and Methods Related Thereto

An adsorbent bed system comprising:

• a first adsorbent bed of adsorbent material capable of selectively removing a target gas from a gaseous mixture, which adsorbent bed is substantially cylindrical shape;
• a second adsorbent bed of adsorbent material capable of selectively removing a target gas from a gaseous mixture, which second adsorbent bed has a substantially cylindrical shape and being disposed about the first bed of adsorbent material and is substantially the same face cross-sectional area as the face cross-sectional area of the first adsorbent bed, wherein the first adsorbent bed and second adsorbent bed are separated by a material that is non-permeable to the gas flowing through the first adsorbent bed and the second adsorbent bed and the non-permeable material prevents leakage of gas between the first adsorbent bed and the second adsorbent bed.
