Abstract

DISCLOSED IS A PROCESS TO PRODUCE A PURIFIED CARBOXYLIC ACID PRODUCT. THE PROCESS COMPRISES REMOVING IMPURITIES FROM A CRUDE CARBOXYLIC ACID SLURRY IN A SOLID-LIQUID DISPLACEMENT ZONE TO FORM A SLURRY PRODUCT. THE SLURRY PRODUCT IF FURTHER TREATED IN A STAGED OXIDATION ZONE AND A CRYSTALLIZATION ZONE TO FROM A CRYSTALLIZED PRODUCT. THE CRYSTALLIZED PRODUCT IS FURTHER COOLED IN A COOLING ZONE AND SUBSEQUENTLY FILTERED AND DRIED IN A FILTRATION AND DRYING ZONE. THE PROCESS PRODUCES PURIFIED CARBOXYLIC ACID PRODUCT HAVING GOOD COLOR AND LOW IMPURITY LEVELS WITHOUT THE USE OF PURIFICATION STEPS LIKE HYDROGENATION.
