Abstract
The various embodiments of the present disclosure relate generally to membranes, and more particularly to carbon molecular sieve membranes for the recovery of anesthetic gases. A membrane according to the disclosed technology includes a carbon molecular sieve (CMS) material configured to receive a gaseous feedstock and a plurality of pores defined by the CMS material, the plurality of pores configured to retain one or more recovered anesthetic products from the gaseous feedstock.
Claims20
A membrane comprising:
- a carbon molecular sieve (CMS) material configured to receive a gaseous feedstock;
- and
- a plurality of pores defined by the CMS material, the plurality of pores configured to retain one or more recovered anesthetic products from the gaseous feedstock, the one or more recovered anesthetic products each having an atomic diameter of at least 3.8 Å.
A method of anesthetic agent recovery, comprising:
- feeding, to a membrane, a gaseous feedstock;
- producing a permeate stream from the membrane comprising one or more permeated products;
- and
- obtaining a retentate stream from the membrane comprising one or more recovered anesthetic products, the one or more recovered anesthetic products having an atomic diameter of at least 3.8 Å.
A method of manufacturing a carbon molecular sieve (CMS) membrane, comprising:
- providing a fiber membrane;
- performing pyrolysis on the fiber membrane, a pyrolysis temperature ranging between 500 degrees Celsius and 1200 degrees Celsius;
- cooling the pyrolyzed fiber membrane to room temperature;
- and
- constructing the CMS membrane from the cooled fiber membrane.
