PURIFIED TEREPHTHALIC ACID (PTA)


A successful collaboration between Johnson Matthey and Dow has achieved a breakthrough PTA process offering improved economics, competitiveness and reliability while delivering a quality PTA product.

This streamlined technology is aptly named COMPRESS™ PTA and is based upon conventional chemistry in combination with a breakthrough combination of proven processes.

COMPRESS™ PTA uses less equipment and a smaller plot space to deliver reduced capital costs, power consumption and maintenance requirements.

 

Our process is also versatile – in addition to PTA it can produce purified isophthalic acid (PIA), which finds great industrial utility as a co-polymer for the production of PET.
