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.
Claims15
A process for the recovery of at least one anesthetic from a gas stream including a mixture of at least two different anesthetics, the process comprising:
- exposing the gas stream to at least one adsorbent having an organophillic pore lattice structure;
- removing from the gas stream the at least one adsorbent containing the adsorbed mixture of at least two anesthetics;
- regenerating the at least one adsorbent in a purge gas by exposing the at least one adsorbent to the purge gas under conditions which desorb the at least two anesthetics from the at least one adsorbent;
- condensing the at least two anesthetics desorbed into the purge stream to provide a condensate comprising a mixture of the at least two anesthetics;
- and
- distilling the mixture of at least two anesthetics to provide a purified at least one anesthetic at a medically acceptable purity level.
A system for the recovery of at least one anesthetic from a gas stream including a mixture of at least two different anesthetics, the system comprising:
- at least one adsorbent having an organophillic pore lattice structure placed in the path of the gas stream;
- a regenerator in which the at least one adsorbent is placed to regenerate the at least one adsorbent in a purge gas by exposing the at least one adsorbent to the purge gas under conditions which desorb the at least two anesthetics from the at least one adsorbent;
- a condenser connected with regenerator for condensing the at least two anesthetics desorbed into the purge stream to provide a condensate comprising a mixture of the at least two anesthetics;
- and
- at least one distillation column for distilling the mixture of at least two anesthetics to provide the at least one anesthetic at a medically acceptable purity level.
