Crude & Pure Terephthalic Acid

Process filters used for filtration of crude and pure terephthalic acid. Mott has been the leader in both crude terephthalic acid (CTA) and purified terephthalic acid (PTA) for decades using both HyPulse® LSI and LSM technologies.  Mott liquid filters are easily configurable to handle multiple wash and purge steps necessary in the CTA and PTA processes to ensure product quality.  Mott filters reduce caustic acid consumption in the CRU, reduce organic loads to wastewater treatment and can recover up to 2 wt.% solids from CTA or PTA applications.  For applications designed around corrosion metal control, the Mott LSI can act as an intermediate filter, removing precipitated corrosion metals before downstream processing.  The average return on investment for a Mott LSI in a CTA or PTA application is 2 years.
