INVISTA’s technology and licensing group, INVISTA Performance Technologies (IPT) and Hengli Petrochemical Co. Ltd (Hengli) have announced the successful start-up of Hengli’s fourth purified terephthalic acid (PTA) line.
This 2.5 million tpy capacity plant, located in Changxing Island, Dalian City, China, utilises INVISTA’s P8 PTA technology with industry leading variable cost, capital productivity, energy usage, water usage, effluent generation and footprint. As a result of the joint effort of all parties involved, the schedule of this project is significantly shorter, with start-up only 22 months after the project kicked off in early March, 2018.
A fifth PTA line, identical to the fourth, is currently under construction and is expected to start-up around the middle of 2020. Hengli also operates another three PTA lines on the same site, each with a capacity of 2.2 million tpy, using INVISTA’s P7 PTA technology. This makes the Hengli site the largest PTA site in the world.
Mike Pickens, IPT President, commented, “IPT congratulate Hengli on the successful start-up. The achievement represents yet another major milestone for Hengli. For INVISTA, it lifts us beyond the 30 million t mark in terms of successful PTA start-ups. IPT is appreciative of the collaborative efforts of the Hengli and INVISTA commissioning teams. The successful start-up of Hengli’s fourth line again demonstrates IN-VISTA’s capability in the global PTA market.”
