Crude & 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 filter technologies.  Mott liquid filters are easily configurable to handle multiple wash and purge steps necessary in CTA and PTA processes to ensure product quality.  Our 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 filter in a CTA or PTA application is only two years.
