Isophthalic Acid Plant

Brief Overview

This 75,000 TPY isophthalic acid plant was shut down during September 2000. It has by-product of 16,500 TPY glacial acetic-acid. Several major upgrades were done. The most recent major upgrade was done in 1999, which included: three Pannevis band filters, two Bird rotary drum filters, three Turbo-dryers, a distillation column for glacial acetic acid, two oxidation reactors, and Nash stainless steel vacuum pumps. Most of the equipment are stainless steel (AISI 316L).
