Abstract

A method of separating a liquid from a liquid-laden solid material includes providing a trough having a deck defining a support surface with passages extending through the support surface. The liquid-laden solid material is deposited onto the support surface so that the liquid-laden solid material is supported by the support surface. A vibratory force is applied to the deck to separate a substantial portion of the liquid from the liquid-laden solid material. The liquid separated from the liquid-laden solid material is directed under gravity force through the passages extending through the support surface. The solid material is conveyed along the support surface by the vibratory force to a solids discharge point.

Claims

1. A method of separating liquid from a liquid-laden solid material, comprising:

providing a trough having a deck and a base defining a base surface, and said deck including a plurality of inverted V-shaped angles extending longitudinally along the trough defining an inclined support surface, each V-shaped angle having a solid first wall surface and a solid second wall surface, the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the trough, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the trough to allow liquid to drain from the solid material and flow through the passage to the trough;

depositing the liquid-laden solid material at a feed point on the support surface so that the liquid-laden solid material is supported by the support surface;

applying a vibratory force to the deck to separate a substantial portion of the liquid from the liquid-laden solid material;

directing the liquid separated from the liquid-laden solid material under gravity force through the passages extending through the support surface; and

conveying the solid material up the inclined support surface by the vibratory force along the support surface to a solids discharge point at an elevation above the feed point.

2. The method of claim 1, in which the base surface positioned below the support surface and in fluid communication with the passages extending through the support surface, the method further comprising transferring the liquid along the base surface to a liquid drainage point.

3. The method of claim 2, in which the base surface is oriented at a decline so that the liquid is transferred vertically downward along the base surface.

4. The method of claim 2, in which a vibratory drive is coupled to the trough to apply the vibratory force to the deck.

5. The method of claim 1, in which the liquid-laden solid material comprises water-laden petroleum coke.

6. A method of separating liquid from a liquid-laden solid material, comprising:

providing a trough having a base surface and a deck defining an inclined support surface including a plurality of inverted V-shaped angles extending longitudinally along the base surface defining said inclined support surface, each V-shaped angle having a solid first wall surface and a solid second wall surface, the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base surface, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the base surface, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the base surface to allow liquid to drain from the solid material and flow through the passage to the base surface;

depositing the liquid-laden solid material at a feed point on the support surface so that the liquid-laden solid material is supported by the support surface;

applying a vibratory force to the deck to separate a substantial portion of the liquid from the liquid-laden solid material;

directing the liquid separated from the liquid-laden solid material under gravity force through the passages extending through the support surface, along the base surface, to a liquid drainage point formed in the deck; and

conveying the solid material up the inclined support surface by the vibratory force along the support surface to a solids discharge point at an elevation above the feed point.

7. The method of claim 6, in which the base surface is oriented at a decline so that the liquid is transferred vertically downward along the base surface.

8. The method of claim 6, in which a vibratory drive is coupled to the trough to apply the vibratory force to the deck.

9. The method of claim 6, in which the liquid-laden solid material comprise water-laden petroleum coke.

10. A method of separating liquid from liquid-laden petroleum coke, comprising:

providing an inclined trough having a base surface, the trough defining a solids discharge point and a liquid drainage point in fluid communication with the base surface;

providing a deck coupled to the trough, the deck defining an inclined support surface positioned above the base surface and in fluid communication with the solids discharge point, the support surface defining passages extending through the support surface and fluidly communicating with the base surface, the support surface including including a plurality of inverted V-shaped angles extending longitudinally along the base surface, each V-shaped angle having a solid first wall surface and a solid second wall surface, the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base surface, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the base surface, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the base surface to allow liquid to drain from the solid material and flow through the passage to the base surface;

depositing the liquid-laden petroleum coke at a feed point on the support surface so that the liquid-laden petroleum coke is supported by the support surface;

applying a vibratory force to the deck to separate a substantial portion of the liquid from the liquid-laden petroleum coke;

directing the liquid separated from the liquid-laden petroleum coke under gravity force through the passages extending through the support surface, along the inclined base surface, and to the liquid drainage point; and

conveying the petroleum coke up the inclined support surface by the vibratory force along the inclined support surface to the solids discharge point at an elevation above the feed point.
