Abstract: A process for the removal and recovery of at least one heavy metal and at least one halogen from a liquid stream in a chemical process is disclosed. The process comprises the steps of contacting the liquid stream with a strong base anion exchange resin; and contacting a discharge stream from the first step with a chelating cation exchange resin. The recovery process optionally includes a step regenerating the anion exchange resin by contacting the anion exchange resin with an anion exchange resin regeneration solution to form recovered heavy metals and halogens. Optimally, the recovery process of the present invention also includes a step of regenerating the chelating cation exchange resin to form recovered heavy metals and halogens.

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.
