Disclosed is a process to produce a purified carboxylic acid slurry. The
process comprises removing impurities from a crystallized product in a
solid liquid displacement zone to form the purified carboxylic acid
slurry. The purified carboxylic acid slurry 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 or filtrate purge.
