System for transporting solids with improved solids packing

摘要

A system includes a solid feed pump having a housing, a rotor disposed in the housing, a curved passage disposed between the rotor and the housing, a solid feed inlet coupled to the curved passage, and a solid feed outlet coupled to the curved passage. Also, a solids packing device is coupled to the solid feed inlet of the solid feed pump. The solids packing device includes a first channel configured to receive a solid feed with a first range of sizes, a second channel configured to receive transport assisting particles (TAP) with a second range of sizes. The first range is different from the second range. A third channel is configured to receive and mix the solid feed and the TAP to provide a solid feed-TAP mixture with the TAP filling interspatial spaces between the solid feed. The third channel is coupled to the solid feed inlet.

1. A system, comprising:
a solids packing device comprising:
a first channel configured to receive a solid feed with a first range of sizes;a second channel configured to receive solid transport assistance particles (TAP) with a second range of sizes, wherein the first range of sizes is different from the second range of sizes;a third channel located downstream of the first and second channels and configured to separately receive and then mix the solid feed and the solid TAP to provide a solid feed-solid TAP mixture with the solid TAP filling interspatial spaces between the solid feed, wherein the first channel and the second channel are oriented to provide the solid feed and the solid TAP, respectively, in a same direction of a flow of the solid feed-solid TAP mixture thru the third channel;a first nozzle having a first wall defining the first channel; anda second nozzle having a second wall, wherein a first pportion of the first wall is disposed within the second wall in a concentric arrangement to define the second channel between the first and second walls, and a second portion of the second wall located downstream of the second nozzle defines the third channel; and a solid feed pump, comprising:
a housing;a passage disposed within the housing;a solid feed inlet configured to receive the solid feed-solid TAP mixture from the third channel and provide the solid feed-solid TAP mixture to the passage;a solid feed outlet coupled to the passage; and at least one disk configured to move the solid fee-solid TAP mixture from the solid feed inlet to the solid feed outlet.
