Abstract
Official abstract text for this publication.
The present invention relates to a process for separating BaCl2 from a CaCl2 brine solution.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for separating BaCl2 from a CaCl2 brine solution comprising contacting a titanium containing material with a BaCl2 containing CaCl2 brine solution, wherein the titanium containing material comprises TiO2. 2. The method of claim 1 , wherein the titanium containing material is hydrated. 3. The method of claim 1 , wherein the titanium containing material further comprises Ti(OH)4. 4. The method of claim 1 , wherein the titanium containing material comprises granules. 5. The method of claim 1 , wherein the titanium containing material comprises powder. 6. The method of claim 1 , wherein the titanium containing material and the CaCl 2 brine solution are mixed together. 7. The method of claim 1 , wherein the CaCl 2 brine solution is passed through a column packed with the titanium containing material in a granular form. 8. The method of claim 1 , wherein the CaCl 2 brine solution is maintained at a pH from about 3 to about 9. 9. The method of claim 8 , wherein the CaCl 2 brine solution is maintained at a pH from about 5.9 to about 6.9. 10. The method of claim 9 , wherein the CaCl 2 brine solution is maintained at a pH of about 6.5. 11. The method of claim 1 , wherein the CaCl 2 brine solution has a concentration between about 10 wt. % to about 30 wt. % CaCl 2 at ambient temperature, based on the total weight of the brine solution. 12. The method of claim 1 , wherein the CaCl 2 brine solution is contacted with the titanium containing material at a temperature between 10° C. and 75° C. 13. The method of claim 12 , wherein the CaCl 2 brine solution is contacted with the titanium containing material at a temperature between 20° C. and 65° C. 14. The method of claim 1 , wherein the titanium containing material has a surface area above 180 m 2 /g.
