Abstract

Described herein are various embodiments of an oxygen concentrator system. In some embodiments, oxygen concentrator system includes one or more components that improve energy usage during operation of the oxygen concentrator system.

Claims (11)

1. An oxygen concentrator apparatus, comprising:

one or more canisters, wherein at least one of the canisters comprises an outlet end having a diameter larger than a diameter of an inlet end of the canister; and

gas separation adsorbent disposed in at one of the canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas; and

wherein the canister is positioned in the oxygen concentrator apparatus such that gas passes through the one or more canisters from the inlet end toward the outlet end during separation of nitrogen from air to produce oxygen enriched gas, and wherein the one or more canisters are substantially filled with gas separation adsorbent, such that the gas separation adsorbent extends through the canister from the inlet of the canister to the outlet of the canister.

2. The oxygen concentrator apparatus of claim 1 , wherein at least one of the canisters comprises one or more baffles.

3. The oxygen concentrator apparatus of claim 1 , wherein at least one canister comprising a first end having a diameter larger than the diameter of a second end of the canister comprises one or more baffles.

4. The oxygen concentrator apparatus of claim 1 , wherein at least one canister comprising a first end having a diameter larger than the diameter of a second end of the canister is configured to produce of flow of gas in the canister having a Reynolds number ranging from about 10 to about 20.

5. The oxygen concentrator apparatus of claim 1 , wherein at least one of the canisters comprises one or more polymers.

6. The oxygen concentrator apparatus of claim 1 , wherein at least one of the canisters is composed of a polymer having a coating comprised of glass.

7. The oxygen concentrator apparatus of claim 1 , wherein at least one of the canisters is composed of a polymer having a coating comprised of one or more metals.

8. The oxygen concentrator apparatus of claim 1 , further comprising a compression system comprising at least one compressor coupled to at least one canister.
