Polycarboxylic acid production system employing cooled mother liquor from oxidative digestion as feed to impurity purge system |
| abstract |
Disclosed is an optimized system for more efficiently and economically producing terephthalic acid. A solvent purification system is employed to remove of at least one aromatic impurity present in a solvent purification feed. At least about 20 weight percent of the solvent purification feed originates from a cooled, post-digestion, TPA-containing slurry. |
