Abstract

This invention is directed to a process for separating a solute from a solute- bearing material. A substantial amount of solute is extracted from the solute-bearing material by contacting particles of the solute-bearing material with globules of an extraction solvent. The particle size of the solute-bearing material and the globule size of the extraction solvent are balanced such that little if any solute or extraction solvent remains in the solute-bearing material.

Claims (21)

1. A process for extracting a solute from a solute-bearing material, comprising:
contacting particles of the solute-bearing material with globules of an extraction solvent in an extraction chamber to extract at least a portion of the solute from the solute-bearing material, wherein the particles and globules are fed to the extraction chamber at an average particle size to average globule size ratio of from 1:0.5 to 1:3; and separating the extracted solute from the extraction solvent.
2. The process of claim 1, wherein the extraction solvent is fed to the extraction chamber such that a major portion of the extraction solvent is fed in its liquid state.
3. The process of claim 1, wherein the particles of solute-bearing material are contacted with the globules of extraction solvent at an extraction chamber pressure greater than that of the solvent's vapor pressure.
4. The process of claim 1, wherein the solvent has a vapor pressure of at least 1 atm at a temperature of 50°C.
5. The process of claim 1, wherein the particles of solute-bearing material fed to the extraction chamber have an average particle size of from 400 microns to 3400 microns.
6. The process of claim 1, wherein the globules of solvent fed to the extraction chamber have an average globule size of from 500 microns to 2500 microns.
7. The process of claim 1, wherein a majority of the particles of solute-bearing material fed to the extraction chamber pass through a 5 mesh sieve, but are retained by a 40 mesh sieve.
8. A process for extracting a solute from a solute-bearing material, comprising:
feeding particles of the solute-bearing material to an extraction chamber, wherein a majority of the particles fed to the extraction chamber pass through a 5 mesh sieve, but are retained by a 40 mesh sieve;
injecting globules of an extraction solvent into the extraction chamber to contact the particles of the solute-bearing material and extract at least a portion of the solute from the solid product, wherein the solvent is injected into the extraction chamber at an average globule size of from 500 microns to 2500 microns;
collecting a mixture of the extracted solute and solvent from the extraction chamber;
and separating the solute from the solvent.
9. The process of claim 8, wherein the particles of the solute-bearing material and the globules of extraction solvent are fed to the extraction chamber at an average particle size to average globule size ratio of from 1:0.5 to 1:3.
10. The process of claim 8, wherein the extraction solvent is fed to the extraction chamber such that a major portion of the extraction solvent is fed in its liquid state.
11. The process of claim 8, wherein the particles of solute-bearing material are contacted with the globules of extraction solvent at an extraction chamber pressure greater than that of the solvent's vapor pressure.
12. The process of claim 8, wherein the solvent has a vapor pressure of at least 1 atm at a temperature of 50°C.
13. The process of claim 8, wherein a majority of the particles of solute-bearing material fed to the extraction chamber pass through a 16 mesh sieve, but are retained by a 40 mesh sieve.
14. The process of claim 8, wherein a majority of the particles of solute-bearing material fed to the extraction chamber pass through a 6 mesh sieve, but are retained by a 25 mesh sieve.
15. A process for extracting a solute from a solute-bearing material, comprising:
feeding particles of the solute-bearing material to an extraction chamber, wherein the particles fed to the extraction chamber have an average particle size of from 400 microns to 3400 microns;
injecting globules of an extraction solvent into the extraction chamber to contact the particles of the solute-bearing material and extract at least a portion of the solute from the solid product, wherein the solvent is injected into the extraction chamber at an average globule size of from 500 microns to 2500 microns;
collecting a mixture of the extracted solute and solvent from the extraction chamber;
and separating the solute from the solvent.
16. The process of claim 15, wherein the particles of the solute-bearing material and the globules of extraction solvent are fed to the extraction chamber at an average particle size to average globule size ratio of from 1:0.5 to 1:3.
17. The process of claim 15, wherein the extraction solvent is fed to the extraction chamber such that a major portion of the extraction solvent is in its liquid state.
18. The process of claim 15, wherein the particles of solute-bearing material are contacted with the globules of extraction solvent at an extraction chamber pressure greater than that of the solvent's vapor pressure.
19. The process of claim 15, wherein the solvent has a vapor pressure of at least 1 atm at a temperature of 50°C.
20. The process of claim 15, wherein the particles of solute-bearing material fed to the extraction chamber have an average particle size of from 400 microns to 3400 microns.
21. The process of claim 15, wherein the globules of solvent fed to the extraction chamber have an average globule size of from 500 microns to 2500 microns.
