Methods and apparatus for isolating carboxylic acid

摘要

Disclosed are methods and apparatus for isolating a carboxylic acid. The processes employ at least two decanter centrifuges and at least one reslurry zone as a product isolation system in a carboxylic acid production process. The product isolation system is employed to isolate purified carboxylic acid particles from an isolation feed slurry comprising an aliphatic acid.
