Hengli starts up 5th PTA line with Invista tech

SHANGHAI, August 4, 2020

Petrochemical major Hengli’s 5th PTA (purified terephthalic acid) line with 2.5 million tonnes per annum (mtpa) capacity, utilising Invista’s industry leading P8 PTA technology, has successfully started up.
This was announced by Invista’s technology and licensing group, Invista Performance Technologies (IPT), and Hengli Petrochemical (Dalian) Co, Ltd (Hengli).
Hengli also operates another 4 PTA lines on the same site on Changxing Island (Dalian), all of which utilise advantaged PTA technology licensed from Invista, with a total capacity of 11.6 mtpa. This makes Hengli the largest PTA producing site in the world. 
With integrated facilities and advantaged variable cost performance, Hengli’s PTA product is very competitive in the marketplace. Adam Sackett, IPT vice president PTA, commented: “I congratulate Hengli on achieving another important milestone this year. The successful start-up of Hengli’s 5th PTA line yet again highlights the quick ramp-up capability of PTA plants utilising our technology. 
“Fast project execution, trouble-free and stable operation at low variable cost, enables our licensees to achieve a good return on their PTA investment.”
Invista’s industry-leading PTA technology, including its latest version of P8 technology, is available as a licence package from IPT. -- Tradearabia News Service
