Abstract

One exemplary embodiment can be a process for removing one or more sulfur compounds from a first liquid. The process can include passing the first liquid through a first inlet and a second liquid through a second inlet of a vessel, passing the first and second liquids through the passageway for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid, and passing the first liquid through the first outlet and the second liquid through the second outlet. Often, the vessel has a plurality of vortex contactors, and a first outlet and a second outlet. The plurality of vortex contactors can include a first vortex contactor, in turn having at least one wall forming a perimeter about an interior region and including a first side and a second side forming a passageway communicating the first liquid from an exterior to the interior region, and a frustum positioned proximate to the passageway and abutting the at least one wall.

First claim

The invention claimed is:

1. A process for removing one or more sulfur compounds from a first liquid comprising:
A) passing the first liquid through a first inlet and a second liquid through a second inlet of a vessel, wherein the vessel further comprises:
1) a plurality of vortex contactors, wherein the plurality of vortex contactors comprises at least a first and a second vortex contactor, each vortex contactor in turn comprising:
a) at least one wall forming a perimeter about an interior region and comprising a first side and a second side forming a passageway communicating liquid from an exterior to the interior region; and
b) a frustum positioned proximate to the passageway and abutting the at least one wall; and

2) a first outlet and a second outlet;

B) swirling the first and second liquids at no more than bout 10 g,
C) passing the first and second liquids through the passageway of the first vortex contactor and passing the first and second liquids though the passageway of the second vortex contactor for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid; and
D) passing the first liquid through the first outlet and the second liquid through the second outlet.

2. The process according to claim 1 , wherein the swirling of the first and second liquids is at no more than about 8 g.

3. The process according to claim 1 , wherein the vessel is substantially cylindrical and orientated substantially horizontal, and the vessel further comprises a first end, a second end, a first side, a second side, a top, and a bottom, wherein the first inlet is formed in the first side and the second inlet is formed in the second side.

4. The process according to claim 1 , wherein the frustum comprises a funnical frustum to direct liquids to a center of the respective vortex contactor.

5. The process according to claim 1 , wherein the first vortex contactor abuts the second contactor.

6. The process according to claim 5 , further comprising passing the first liquid from the first inlet to a first manifold and the second liquid from the second inlet to a second manifold wherein the first manifold comprises a conduit and the second manifold comprises a plurality of conduits wherein the conduits of the second manifold sandwich the conduit of the first manifold; and passing the first liquid from the first manifold to the plurality of vortex contactors, and passing the second liquid from the second manifold to the plurality of vortex contactors.

7. The process according to claim 6 , wherein the plurality of conduits of the second manifold comprises at least a first conduit and a second conduit wherein the first conduit communicates with the first vortex contactor and the second conduit communicates with the second vortex contactor.

8. The process according to claim 5 , further comprising passing the first liquid from the first inlet to a first manifold and the second liquid from the second inlet to a second manifold wherein the first manifold comprises a plurality of conduits and the second manifold comprises a conduit wherein the conduits of the first manifold sandwich the conduit of the second manifold; and passing the first liquid from the first manifold to the plurality of vortex contactors, and passing the second liquid from the second manifold to the plurality of vortex contactors.

9. The process according to claim 1 , wherein the vessel is substantially cylindrical and orientated substantially vertical, and the vessel further comprises a first end, a second end, a first side, a second side, a top, and a bottom, wherein the first inlet is formed in the first side and the second inlet is formed on the second side.

10. The process according to claim 9 , wherein plurality of vortex contactors comprises a first group of vortex contactors at a first elevation and a second group of vortex contactors at a second elevation.

11. The process according to claim 1 , wherein the first and second liquids are contacted counter-currently in the passageways of the vortex contactors.
