Abstract: A system and process for the recovery of at least one anesthetic from a gas stream including at least two anesthetics. The recovery includes adsorption by exposing the gas stream to an adsorbent. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least two anethetics from the adsorbent. The at least two anesthetics (and impurities or reaction products) are condensed from the purge gas and subjected to fractional distillation to provide a recovered anesthetic.

Abstract: A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.
