Abstract

A gas injection assembly for injecting a gas into a liquid to form a solution includes a vessel that receives the liquid, a flow channel that conveys the liquid from the vessel through an upstream inlet to a downstream outlet that is configured to dispense the solution, and a sparger having a porous surface positioned in the flow channel such that the liquid flows across the porous surface and the porous surface injects the gas into the liquid as the liquid flows across the porous surface.

First claim

What is claimed is:

1. A gas injection assembly for injecting a gas into a liquid to form a solution, the gas injection assembly comprising:
a vessel configured to receive the liquid, wherein the vessel has an open end;
a top cap on the open end of the vessel and having an intake passageway;
an intake member defining a central bore, the intake member coupled to the top cap and configured to receive the liquid from the vessel and dispense the liquid to the intake passageway;
a flow channel having an upstream inlet configured to receive the liquid from the intake passageway and a downstream outlet configured to dispense the solution; and
a sparger having a porous surface positioned in the flow channel, wherein the sparger is configured to inject the gas through the porous surface into the liquid to thereby form the solution.

2. The gas injection assembly according to claim 1 , wherein the vessel has a closed end, and wherein the intake member has a first end coupled to the top cap and a second end opposite the first end; and
wherein the second end of the intake member is positioned in the vessel and located nearer the closed end of the vessel than the open end of the vessel.

3. The gas injection assembly according to claim 2 , wherein the top cap has a connection device that permits the first end of the intake member to be removably coupled to the top cap.

4. The gas injection assembly according to claim 1 , wherein the flow channel has a center axis along which the sparger extends, and wherein the liquid flows under laminar flow conditions across the porous surface of the sparger.

5. The gas injection assembly according to claim 4 , wherein the flow channel has an inner perimeteral surface spaced apart from the porous surface, and wherein the porous surface and the inner perimeteral surface are concentric about the center axis.

6. The gas injection assembly according to claim 5 , wherein the porous surface and the inner perimeteral surface are spaced apart a distance of 1/16 inches.

7. A gas injection assembly for injecting a gas into a liquid to form a solution, the gas injection assembly comprising;
a vessel configured to receive the liquid;
a flow channel having an upstream inlet configured to receive the liquid from the vessel and a downstream outlet; and
a sparger having a porous surface positioned in the flow channel, wherein the sparger is configured to inject the gas through the porous surface into the liquid to thereby form the solution; and
wherein the downstream outlet is configured to dispense the solution back into the vessel.

8. The gas injection assembly according to claim 7 , further comprising a top cap on the vessel and having a dispensing passageway configured to receive the solution from the downstream outlet and dispense the solution back into the vessel.

9. The gas injection assembly according to claim 8 , further comprising a dispensing member configured to receive the solution from the dispensing passageway and dispense the solution back into the vessel.

10. The gas injection assembly according to claim 9 , wherein the vessel has a closed end, and wherein the dispensing member has a first end coupled to the top cap and a second end opposite the first end; and
wherein the second end of the dispensing member is positioned in the vessel and located nearer the closed end of the vessel than the open end of the vessel.

11. The gas injection assembly according to claim 10 , wherein the top cap has a connection device that permits the first end of the intake member to be removably coupled to the top cap.

12. A gas injection assembly for injecting a gas into a liquid to form a solution, the gas injection assembly comprising:
a first vessel configured to receive the liquid, the first vessel having an open end and a closed end;
a second vessel having an open end and a closed end;
a top cap on the open end of the first vessel and having an intake passageway;
an intake member defining a central bore and having a first end coupled to the top cap and a second end opposite the first end, wherein the second end is configured to receive the liquid from the first vessel and the first end is configured to dispense the liquid to the intake passageway, and wherein the second end is positioned in the first vessel and located nearer the closed end of the first vessel than the open end of the first vessel;
a flow channel having a upstream inlet configured to receive the liquid from the intake passageway and a downstream outlet configured to dispense the solution into the second vessel; and
a sparger having a porous surface positioned in the flow channel, wherein the sparger is configured to inject the gas through the porous surface into the liquid to thereby form the solution.

13. The gas injection assembly according to claim 12 , wherein the flow channel has a center axis along which the sparger extends, and wherein the liquid flows under laminar flow conditions across the porous surface of the sparger.

14. The gas injection assembly according to claim 13 , wherein the flow channel has an inner perimeteral surface spaced apart from the porous surface, and wherein the porous surface and the inner perimeteral surface are concentric about the center axis.

15. The gas injection assembly according to claim 14 , wherein the porous surface and the inner perimeteral surface are spaced apart a distance of 1/16 inches.

16. The gas injection assembly according to claim 15 , wherein the top cap has a connection device that permits the first end of the intake member to be removably coupled to the top cap.
