Polycarboxylic acid production system employing enhanced multistage oxidative digestion |
摘要 |
Disclosed is an optimized system for more efficiently and economically producing terephthalic acid. The system includes a multi-stage oxidative digestion system for processing an improved initial slurry from primary oxidation. The multi-stage digestion system is capable of adequately purifying the improved initial slurry without requiring significant liquor exchange between primary oxidation and oxidative digestion.
