Rotary fluid processing systems and associated methods are disclosed. A purification system in accordance with the particular embodiment includes a rotatable adsorbent-containing heat/mass transfer element that is generally symmetric about a rotation axis, and includes multiple radial flow paths oriented transverse to the rotation axis and multiple axial flow paths oriented transverse to the radial flow paths. The axial flow paths and radial flow paths are in thermal communication with each other, and are generally isolated from fluid communication with each other at the heat transfer element. Particular embodiments can further include a housing arrangement having multiple manifolds with individual manifolds having an entry port and an exit port, and with individual manifolds having different circumferential locations relative to the rotation axis. Still further embodiments can include a seal arrangement positioned between the heat transfer element and the housing arrangement to expose the radial flow paths, but not the axial flow paths, to the entry and exit ports of one of the manifolds, and expose the axial flow paths, but not the radial flow paths, to the entry and exit ports of another of the manifolds.
