Abstract

A process for producing a dried carboxylic acid cake, said process comprising: (a) oxidizing in an oxidation zone an aromatic feedstock to produce a carboxylic acid slurry; (b) removing in a solvent liquor exchange zone impurities from a said carboxylic acid slurry to form a carboxylic acid cake with solvent, a mother liquor stream, and a solvent mother liquor stream; wherein said solvent comprises acetic acid; (c) adding water in a counter current water wash zone to said carboxylic cake with solvent to produce a water-wet carboxylic acid cake and a byproduct liquor stream; and (d) drying said water-wet carboxylic acid cake in a drying zone to form said dried carboxylic acid cake; wherein said water-wet cake maintains the form of a cake between step (c) and (d).
