PROCESS FOR IMPROVED META-XYLENE YIELD FROM C8 AROMATICS |
| 摘要 |
Meta-xylene is recovered from admixture with other C8 aromatic hydrocarbons including ortho-xylene by liquid phase adsorptive separation. Performance is improved by reducing the concentration of ortho-xylene through adding a sidecut to a prefractionator preparing the feedstock to adsorptive separation. |
