Transportation of refinery solids waste

1. An apparatus for mixing contents of a tank including sedimentary material, the apparatus comprising:

an agitator;

an elongated and expandable support including a plurality of detachable sections, the support having a distal end configured to connect to the agitator;

a frame configured to be connected to the tank adjacent an opening in the tank; and

an actuatable connector for interconnecting the frame on the tank to the support,

wherein the actuatable connector is configured to be actuated in order to lift a first portion of the support above the frame on the tank while a second portion of the support below the frame is maintained in a substantially fixed position with respect to the frame, to thereby cause a gap between the first portion and the second portion, enabling at least one of the detachable sections to be inserted into the gap; and

wherein the actuatable connector includes at least one actuator having a first end configured to engage the frame on the tank and a second end configured to engage the support, the at least one actuator being configured to selectively cause the actuatable connector to exert a force through the frame and the tank to lift the first portion in order to cause the gap, and simultaneously lower the first portion and the second portion when the at least one detachable section is interconnected between the first portion and the second portion.

2. The apparatus of claim 1 , wherein each of the plurality of sections of the support includes and upper flange for connection to the first portion when inserted in the gap and a lower flange for connection to the second portion when inserted in the gap.

3. The apparatus of claim 1 , wherein the support includes a vacuum tube having a channel for removing material from the tank.

4. The apparatus of claim 3 , further comprising a first pump for drawing the material from the tank into the vacuum tube.

5. The apparatus of claim 4 , further comprising a second pump, and wherein the first pump is configured for location inside the tank and the second pump is configured for location external to the tank.

6. The apparatus of claim 5 , wherein a flexible tube defines a flow path between the first pump and the second pump.

7. The apparatus of claim 1 , wherein the first pump is configured to be powered by a first hydraulic motor and wherein the agitator is configured to be powered by a second hydraulic motor.

8. The apparatus of claim 1 , wherein the at least one actuator includes at least one of a chain, a belt, a gear, a hydraulic cylinder, an air cylinder, and a screw.

9. The apparatus of claim 1 , further comprising at least one mount at a distal end of the support, the at least one mount for supporting an opening of a vacuum tube proximate the agitator, such that when the agitator mixes material in the tank, the opening of the vacuum tube is positioned to draw material therethrough.

10. The apparatus of claim 1 , wherein the support is tubular and is configured as a channel for evacuating material from the tank through the support.

11. The apparatus of claim 1 , wherein the agitator includes a non-sparking motor, a rotatable shaft, and at least one blade connected to the shaft.

12. The apparatus of claim 1 , wherein the support includes a rigid tube having a channel extending therethrough.

13. The apparatus of claim 12 , wherein the channel defines a distal opening for receiving material from the tank.

14. The apparatus of claim 13 , wherein the agitator is positioned proximate the distal opening.

15. The apparatus of claim 1 , wherein the at least one actuator is configured to cause the actuatable connector to change the position of the agitator relative to the frame.

16. The apparatus of claim 1 , wherein the actuatable connector includes a connector configured to secure the agitator at a first depth in the tank.

17. The apparatus of claim 16 , wherein the at least one actuator is configured to cause the actuatable connector to lower the agitator to a second depth in the tank deeper than the first depth.

18. The apparatus of claim 17 , wherein the at least one actuator is configured to cause the actuatable connector to raise the agitator from the second depth to the first depth.

19. The apparatus of claim 1 , wherein the frame is configured for mounting about an opening in a refinery tank, the agitator is configured to cause at least one blended area within the refinery tank, and the pump is configured to withdraw material from the at least one blended area.

20. An apparatus for mixing tank contents including sedimentary material, the apparatus comprising:

an agitator;

an elongated and expandable support including a plurality of detachable sections, the support having a distal end configured to connect to the agitator;

a frame configured for disposition adjacent an opening in a top of the tank;

an actuatable connector for interconnecting the frame to the support, wherein the connector is configured to be actuated in order to lift a first portion of the support above the frame while a second portion of the support below the frame is maintained in a substantially fixed position with respect to the frame, to thereby cause a gap between the first portion and the second portion, enabling at least one of the detachable sections to be inserted into the gap; and

at least one actuator for selectively causing the actuatable connector to lift the first portion in order to cause the gap, and for simultaneously lowering the first portion and the second portion when the at least one detachable section is interconnected between the first portion and the second portion; and

a pump, wherein the pump is configured to be positioned within the tank such that, when the agitator mixes material, the material may be withdrawn through the distal opening,

wherein the support includes a rigid tube having a channel extending therethrough, the channel defines a distal opening for receiving material from the tank, the agitator is positioned proximate the distal opening.
