Abstract

Claims (29)

1. A method to enhance conveyance of material from a material source to a material receiver and provide fluid communication between the material source and a refinery apparatus, the refinery apparatus comprising a tower and the material receiver located at an elevated position associated with the tower relative to the material source, the tower including a plurality of zones located in different regions of the tower, a respective zone of the plurality of zones sized to receive a respective amount of material, the method comprising:

supplying a pressurized fluid to a plurality of vacuum generators;

generating, via the plurality of vacuum generators by use of the pressurized fluid, a vacuum flow through a suction manifold, thereby to provide a suction flow path for the vacuum flow between the plurality of vacuum generators and the material receiver and through a conveyance manifold with the material source, thereby to provide a conveyance flow path for the vacuum flow between the material source and the material receiver;

passing the vacuum flow into a sound attenuation chamber to reduce a sound level generated by the vacuum flow;

conveying material from the material source via the vacuum flow through the conveyance manifold and into the material receiver to at least partially fill the material receiver; and

depositing at least a portion of the material from the material receiver through a material discharge outlet of the material receiver into the tower of the refinery apparatus, the depositing material into the tower including controlling the depositing of the respective amount of material into a respective zone of the plurality of zones.

2. The method of claim 1 , wherein the material receiver includes one or more level switch sensors configured to generate signals indicative of one or more fill levels of material in the material receiver, and the method further comprises:

selecting a first respective zone of the plurality of zones sized to receive a first respective amount of material;

conveying material into the material receiver;

receiving, via a fill controller, one or more sensor signals from the one or more level switch sensors indicating the material receiver is filled with the first respective amount of material for the first respective zone; and

suspending the conveyance of material into the material receiver once the sensor signal is received.

3. A method to enhance conveyance of material from a material source to a material receiver and provide fluid communication between the material source and a tower of a refinery apparatus, the material receiver located at an elevated position relative to the material source, the tower comprises a plurality of zones located in different regions of the tower, a respective zone of the plurality of zones being sized to receive a respective amount of material, the method comprising:

supplying a pressurized fluid to a plurality of vacuum generators;

generating, via the plurality of vacuum generators by use of the pressurized fluid, a vacuum flow through a suction manifold, thereby to provide a suction flow path for the vacuum flow between the plurality of vacuum generators and the material receiver and through;

a conveyance manifold with the material source, thereby to provide a conveyance flow path for the vacuum flow between the material source and the material receiver;

passing the vacuum flow from the material receiver into a sound attenuation chamber, thereby to reduce a sound level generated by the vacuum flow;

conveying material from the material source via the vacuum flow through the conveyance manifold and into the material receiver to at least partially fill the material receiver; and

depositing at least a portion of the material from the material receiver through a material discharge outlet of the material receiver into the tower of the refinery apparatus, the depositing material into the tower comprises controlling the depositing of the respective amount of material into a respective zone of the plurality of zones of the tower of the refinery apparatus.

4. The method of claim 3 , further comprising receiving the material from the material receiver via a conveyance chute connected to a discharge end of the material receiver and depositing the material into the refinery apparatus.

5. The method of claim 3 , further comprising circulating the vacuum flow at a receiving end of the material receiver with a cyclone apparatus approximate the receiving end of the material receiver, the circulating of the vacuum flow separating at least a portion of the conveyed material from the vacuum flow.

6. The method of claim 3 , further comprising dislodging any material collecting at the material discharge outlet of the material receiver.

7. The method of claim 3 , wherein dislodging any material collecting at the material discharge outlet comprises vibrating one or more of (1) a conveyance chute connected to a material receiver and depositing the material into the refinery apparatus, or (2) the conveyance manifold connected to a material receiver and depositing the material into the refinery apparatus.

8. The method of claim 3 , wherein dislodging any material collecting at the material discharge outlet comprises directing compressed fluid from a pneumatic fluidizer attached approximate the discharge end of the material receiver to aerate at least a portion of an inner volume of the material receiver.

9. The method of claim 3 , wherein the material receiver comprises one or more level switch sensors configured to generate signals indicative of one or more fill levels of material in the material receiver, and the method further comprises:

selecting a first respective zone of the plurality of zones sized to receive a first respective amount of material;

conveying material into the material receiver;

receiving, via a fill controller, one or more sensor signals from the one or more level switch sensors indicating the material receiver is filled with the first respective amount of material for the first respective zone; and

suspending the conveyance of material into the material receiver once the sensor signal is received.

10. The method of claim 3 , further comprising actuating a gate valve attached to the material receiver and movable by a pneumatic actuator to control the flow path of material between the material receiver and the refinery apparatus.
