Abstract

An agitator assembly for use in a gas separator includes a central hub and at least one blade affixed to the central hub. The blade includes a leading end, a trailing end, a first curved portion adjacent to the leading end and a second curved portion adjacent to the trailing end. In a particularly preferred embodiment, the first and second curved portions are substantially parabolic and have foci on opposite sides of the blade.

Claims (38)

1. An agitator assembly for use in a gas separator;

the agitator assembly comprising:

a central hub; and

a blade affixed to the central hub; wherein the blade includes:

a leading end;

a trailing end;

a first curved portion adjacent to the leading end; a second curved portion adjacent to the trailing end, and

wherein the first curved portion and the second curved portion are substantially parabolic and where the foci for the first and second curved portions are on opposite sides of the blade.

2. The agitator assembly of claim 1 , wherein the blade further comprises a linear middle portion between the first curved portion and the second curved portion.

3. The agitator assembly of claim 1 , wherein the first curved portion and second curved portion adjoin at an inflection point.

4. The agitator assembly of claim 1 , wherein the blade is configured as a substantially “backward-S” shape.

5. The agitator assembly of claim 1 , wherein the blade further comprises a centerline that intersects the center of mass of the blade and extends substantially parallel with the longitudinal axis of the hub and wherein the leading end and the trailing end are on opposite sides of the centerline.

6. A gas separator comprising:

a lift generator; and

an agitator assembly having a plurality of blades, wherein each of the blades includes a first curved portion and a second curved portion.

7. The gas separator of claim 6 , wherein the agitator assembly further comprises a central hub, and wherein the plurality of blades are connected to the central hub.

8. The gas separator of claim 6 , wherein each of the plurality of blades further includes:

a leading end; and

a trailing end.

9. The gas separator of claim 8 , wherein the first curved portion and second curved portion adjoin at an inflection point.

10. The gas separator of claim 9 , wherein the first curved portion and the second curved portion are substantially parabolic and where the foci for the first and second curved portions are on opposite sides of the blade.

11. The gas separator of claim 10 , wherein the blade is configured as a substantially “Backward-S” shape.

12. The gas separator of claim 11 , wherein the blade further comprises a centerline that intersects the center of mass of the blade and extends substantially parallel with the longitudinal axis of the hub.

13. The gas separator of claim 12 , wherein the leading end and the trailing end are on opposite sides of the centerline.

14. A pumping system comprising:

a pump assembly;

a motor configured to drive the pump assembly; and

a gas separator connected to the pump assembly, wherein the gas separator includes:

a lift inducer; and

an agitator assembly having a plurality of blades, wherein each of the blades includes a first curved portion and a second curved portion.

15. The pumping system of claim 14 , wherein the agitator assembly further comprises a central hub, and wherein the plurality of blades are connected to the central hub.

16. The pumping system of claim 15 , wherein each of the plurality of blades further includes:

a leading end; and

a trailing end.

17. The pumping system of claim 16 , wherein the first curved portion and second curved portion adjoin at an inflection point.

18. The pumping system of claim 17 , wherein the first curved portion and the second curved portion are substantially parabolic and where the foci for the first and second curved portions are on opposite sides of the blade.

19. The pumping system of claim 18 , wherein the blade is configured as a substantially “backward-S” shape.

20. The pumping system of claim 19 , wherein the blade further comprises a centerline that intersects the center of mass of the blade and extends substantially parallel with the longitudinal axis of the hub and wherein the leading end and the trailing end are on opposite sides of the centerline.
