Abstract

A method for the recovery of carboxylic acid is disclosed. The method comprises the steps of introducing a liquid slurry comprising water, crystallized carboxylic acid such as terephthalic acid, isophthalic acid, trimellitic acid, and impurities into a high pressure rotary filter; filtering said slurry and collecting at least some of the solid portion; passing the collected solid portion to a rotary valve comprising a temperature control system; controlling the temperature in the rotary valve through the temperature control system; and removing the solid portion from the rotary valve. The rotary valve comprises a valve case and a rotor, and the temperature control system controls the temperature difference between the valve case and the rotor.
