Purified Terephthalic Acid (PTA)​

    PTA production generates fine catalyst residues and organic solidsthat must be separated efficiently to meet product purity standards.JOECHRE filters provide high-throughput clarification of motherliquors and purification stages, enabling recovery of acetic acid orcatalyst solutions with minimal product loss. The closed, automatedoperation reduces emissions and operator exposure, while the abilityto discharge dry or slurry cake provides flexibility for recovery ordisposal processes.
