1. A method to regenerate an adsorbent bed containing one or more chemical moieties adsorbed onto the adsorbent bed, the method comprising:
a) vaporizing an inert chemical fluid to form an inert gas medium,
b) passing the inert gas medium through the adsorbent bed to sufficiently heat the adsorbent bed to effect thermal desorption of the one or more chemical moieties adsorbed onto the adsorbent bed and/or to act as a sweep gas to purge out the desorbed chemical moieties, to form an inert gas medium containing the one or more desorbed, gaseous chemical moieties,
c) passing the inert gas medium containing the one or more desorbed, gaseous chemical moieties through a condenser maintained at a temperature sufficient to condense the inert gas medium containing the one or more desorbed, gaseous chemical moieties, to form a condensed inert chemical fluid and the one or more desorbed, gaseous chemical moieties,
d) separating the condensed inert chemical fluid from the one or more desorbed, gaseous chemical moieties,
e) collecting or further processing the one or more desorbed, gaseous chemical moieties, and
f) returning the condensed inert chemical fluid for reuse in step a) above.
