Abstract

A mixing assembly comprises a tubular member and a spherical body disposed within a portion of the tubular member. The spherical body has a central volume, and a wall defined by an outside diameter and an inside diameter. The spherical body includes an inlet side and an outlet side, and a plurality of channels formed in each of inlet side and outlet side. The channels are oriented toward a center of the central volume.

First claim

The invention claimed is:

1. A mixing assembly, comprising:
a tubular member; and
a spherical body disposed within a portion of the tubular member, the spherical body having:
an outer surface that includes an outside diameter,
an inner surface that includes an inside diameter defining a spherical central volume, and a wall between the inner surface and the outer surface, wherein the spherical body includes an inlet side and an outlet side,
a plurality of channels formed through the wall and extending between the inner surface and the outer surface in each of the inlet side and the outlet side, wherein each of the plurality of channels are disposed outwardly of the spherical central volume and oriented toward a geometric center of the spherical central volume; and
a pair of arc-shaped flush windows formed in areas of the spherical body not occupied with the plurality of channels.

2. The mixing assembly of claim 1 , wherein the inside diameter of the spherical body is greater than an inside diameter of the tubular member.

3. The mixing assembly of claim 1 , wherein the arc-shaped flush windows are 180 degrees apart.

4. The mixing assembly of claim 1 , further comprising an injection nozzle coupled to the tubular member.

5. The mixing assembly of claim 4 , wherein the injection nozzle is in the form of a Y-shaped body or a cylindrical tube.

6. The mixing assembly of claim 1 , wherein each of the plurality of channels in the inlet side are smaller than each of the plurality of channels in the outlet side.

7. The mixing assembly of claim 1 , wherein the inlet side is 180 degrees from the outlet side.

8. The mixing assembly of claim 1 , wherein the mixing assembly is located upstream of a desalter system.

9. A mixing assembly, comprising:
a tubular member comprising an upstream flow opening and a downstream flow opening; and
a spherical body disposed within a portion of the tubular member and between the upstream flow opening and the downstream flow opening, the spherical body having
an outer surface that includes an outside diameter,
an inner surface that includes an inside diameter defining a spherical central volume,
a wall between the inner surface and the outer surface,
a plurality of channels formed through the wall and extending between the inner surface and the outer surface in an inlet side and an outlet side of the spherical body, and
a pair of flush windows formed in areas of the spherical body not occupied with the plurality of channels, wherein the spherical body is rotatable between a first position and a second position, wherein in the first position the plurality of channels formed in the inlet side and the outlet side are positioned between the respective upstream and downstream flow paths of the tubular member and the spherical central volume, and in the first position the pair of flush windows are positioned between one or more sidewalls of the tubular member and the spherical central volume, wherein in the second position the pair of flush windows are positioned between the respective upstream and downstream flow paths of the tubular member and the spherical central volume, and in the second position the plurality of channels formed in the inlet side and the outlet side are positioned between one or more walls of the tubular member and the spherical central volume.

10. The mixing assembly of claim 9 , wherein each of the plurality of channels are oriented toward a geometric center of the spherical central volume.

11. The mixing assembly of claim 9 , wherein the inside diameter of the spherical body is greater than an inside diameter of the tubular member.

12. The mixing assembly of claim 9 , wherein the flush windows are 180 degrees apart.

13. The mixing assembly of claim 9 , wherein each of the flush windows are arc-shaped.

14. The mixing assembly of claim 13 , further comprising an injection nozzle coupled to the tubular member.

15. The mixing assembly of claim 9 , wherein each of the plurality of channels in the inlet side are smaller than each of the plurality of channels in the outlet side.

16. A mixing assembly, comprising:
a tubular member comprising an upstream flow opening and a downstream flow opening;
a spherical body disposed within a portion of the tubular member and between the upstream flow opening and the downstream flow opening, the spherical body having:
an outer surface that includes an outside diameter,
an inner surface that includes an inside diameter defining a spherical central volume, and a wall between the inner surface and the outer surface,
an inlet side and an outlet side, and
a plurality of channels formed through the wall and extending between the inner surface and the outer surface in each of the inlet side and outlet side, wherein each of the plurality of channels are disposed outwardly of the spherical central volume and oriented toward a geometric center of the spherical central volume; and

an injection nozzle coupled to the tubular member and extending at least partially into the upstream flow opening of the tubular member.

17. The mixing assembly of claim 16 , wherein each of the plurality of channels are oriented toward a geometric center of the spherical central volume, and wherein the inside diameter of the spherical body is greater than an inside diameter of the tubular member.

18. The mixing assembly of claim 16 , wherein the inlet side is 180 degrees from the outlet side.

19. The mixing assembly of claim 16 , wherein the spherical body includes a pair of flush windows formed in areas of the spherical body not occupied with the plurality of channels.

20. The mixing assembly of claim 16 , wherein the injection nozzle is in the form of a Y-shaped body or a cylindrical tube.
