Method for purifying crude carboxylic acid slurry |
| abstract |
A method for producing a purified carboxylic acid product is disclosed. The method includes removing impurities from the crude carboxylic acid slurry in a solid-liquid displacement zone to form a slurry product. The slurry product is further processed in a staged oxidation zone and a crystallization zone to form a crystallization product. The crystallized product is further cooled in a cooling zone followed by filtration and drying in a filtration and drying zone. This method produces a purified carboxylic acid having excellent color and low impurity levels without using a purification step such as hydrogenation. |
