Abstract
Official abstract text for this publication.
A materials-separation process includes a sorting operation in which plastics materials including at least first and second plastics materials are sorted from paper and metal materials so that the first plastics material may be separated from the second plastics material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A separation process comprising: introducing a plastics material having a first material density and a plastics material having a second, different material density into a tank, separating the plastics material having a first material density from the different plastics material having a second material density using fluid comprising vegetable oil and an additive, wherein the separating includes agitating in the tank, wherein the fluid has a fluid density greater than the second material density. 2. The separation process of claim 1 , wherein the second material density is in a range of 0.89 g/cm 3 to less than 0.92 g/cm 3 . 3. The separation process of claim 2 , wherein the fluid density is in a range of 0.92 g/cm 3 to 0.94 g/cm 3 . 4. The separation process of claim 3 , wherein the fluid density is in the range of 0.92 g/cm 3 to 0.93 g/cm 3 . 5. The separation process of claim 4 , wherein the fluid density is in the range of 0.924 g/cm 3 to 0.928 g/cm 3 . 6. The separation process of claim 3 , wherein the first material density is in a range of 0.94 g/cm 3 to 0.97 g/cm 3 . 7. The separation process of claim 1 , further comprising the operation of cleaning the first plastics material and the second plastics materials to remove contaminants adhering to the first and second plastics materials. 8. The separation process of claim 7 , wherein the operation of cleaning happens before the operation of separating. 9. The separation process of claim 8 , wherein the second material density is in a range of 0.89 g/cm 3 to less than 0.92 g/cm 3 . 10. The separation process of claim 9 , wherein the fluid density is in a range of 0.92 g/cm 3 to 0.94 g/cm 3 . 11. The separation process of claim 10 , wherein the fluid density is in the range of 0.924 g/cm 3 to 0.928 g/cm 3 . 12. The separation process of claim 10 , wherein the first material density is in a range of 0.94 g/cm 3 to 0.97 g/cm 3 . 13. The separation process of claim 1 , wherein the additive is configured to maximize oxidative stability of the vegetable oil. 14. The separation process of claim 13 , wherein the second material density is in a range of 0.89 g/cm 3 to less than 0.92 g/cm 3 , the fluid density is in a range of 0.92 g/cm 3 to 0.94 g/cm 3 , and the first material density is in a range of 0.94 g/cm 3 to 0.97 g/cm 3 . 15. The separation process of claim 14 , further comprising the operation of cleaning the first plastics material and the second plastics materials to remove contaminants adhering to the first and second plastics materials. 16. The separation process of claim 15 , wherein the operation of cleaning happens before the operation of separating. 17. The separation process of claim 1 , wherein the additive is configured to decrease surface tension. 18. The separation process of claim 17 , wherein the second material density is in a range of 0.89 g/cm 3 to less than 0.92 g/cm 3 , the fluid density is in a range of 0.92 g/cm 3 to 0.94 g/cm 3 , and the first material density is in a range of 0.94 g/cm 3 to 0.97 g/cm 3 . 19. The separation process of claim 18 , further comprising the operation of cleaning the first plastics material and the second plastics materials to remove contaminants adhering to the first and second plastics materials. 20. The separation process of claim 19 , wherein the operation of cleaning happens before the operation of separating.
