Particle disengagement device
A particle disengagements device comprising a baffle plate, wherein the baffle plate comprises one or more guide baffles and one or more separation baffles, wherein the one or more guide baffles and the one or more separation baffles define one or more air flow paths and one or more solid flow paths and associated systems and methods.
1. A vessel comprising:
a fluidized bed;
one or more cyclones; and
a particle disengagement device comprising
a circular baffle plate,
wherein the circular baffle plate comprises one or more guide baffles and one or more separation baffles,
wherein the one or more guide baffles and the one or more separation baffles define one or more air flow paths and one or more solid flow paths;
wherein the one or more guide baffles and the one or more separation baffles each comprise a protrusion having a length in the range of from 0.1 to 8 inches;
wherein the one or more guide baffles are spaced apart a distance in the range of from 4 inches to 25 inches; and
wherein the one or more separation baffles are spaced apart a distance in the range of from 4 inches to 25 inches.
2. The vessel of claim 1 , wherein the one or more cyclones comprise one or more primary cyclones and one or more secondary cyclones.
3. The vessel of claim 2 , wherein the one or more cyclones comprise one or more diplegs.
4. The vessel of claim 3 , wherein the one or more diplegs extend through the particle disengagement device.
5. The vessel of claim 1 , wherein the circular baffle plate has a diameter in the range of from 1 meter to 15 meters.
6. The vessel of claim 1 , wherein the circular baffle plate has a height in the range from 1 inch to 20 inches.
7. The vessel of claim 1 , wherein the one or more guide baffles comprise 10 to 60 guide baffles and the one or more separation vessel comprise 10 to 60 separation baffles.
8. The vessel of claim 1 , wherein the protrusion has a rectangular cross-sectional shape.
9. A method comprising:
providing a vessel, wherein the vessel comprises:
a fluidized bed;
one or more cyclones; and
a particle disengagement device:
wherein the particle disengagement device comprises a circular baffle plate comprising one or more guide baffles and one or more separation baffles, and
wherein the particle disengagement device is disposed within the vessel at an elevation above the fluidized bed and below a portion of the one or more cyclones; and
introducing a gas/solid feed into the vessel.
10. The method of claim 9 , further comprising removing solids from the gas/solid feed.
11. The method of claim 9 , wherein the one or more guide baffles and the one or more separation baffles each comprise a protrusion having a length in the range of from 0.1 to 8 inches.
12. The method of claim 11 , wherein the protrusion has a rectangular cross-sectional shape.
13. The method of claim 9 , wherein the one or more guide baffles are spaced apart a distance in the range of from 4 inches to 25 inches.
14. The method of claim 9 , wherein the one or more separation baffles are spaced apart a distance in the range of from 4 inches to 25 inches.
15. The method of claim 9 , wherein the one or more cyclones comprise one or more diplegs.
16. The method of claim 9 , wherein the one or more guide baffles comprise 10 to 60 guide baffles and the one or more separation vessel comprise 10 to 60 separation baffles.
