China: Plant Engineering Hengli Petrochemical Launches Fourth PTA Plant in China
With a capacity of 2.5 million tonnes, the new Hengli facility has utilised Invista’s P8 PTA technology. The company is also developing a fifth PTA line which should be operational by the second half of 2020.
Shanghai/China – Invista’s technology and licensing group, Invista Performance Technologies (IPT) and Hengli Petrochemical (Dalian) Co. (Hengli) have recently announced the successful start-up of Hengli’s fourth purified terephthalic acid (PTA) line. The 2.5 million tonne per annum capacity plant, located in Changxing Island, Dalian City, Liaoning Province, utilises Invista’s P8 PTA technology with industry leading variable cost, capital productivity, energy usage, water usage, effluent generation and footprint. The facility came online on January 8, 2020.
As the result of joint effort of all parties involved, the schedule of this project is significantly shorter than other PTA projects, with start-up only 22 months after the project kicked off in early March, 2018.
A fifth PTA line, identical to the fourth PTA line, is currently under construction and is expected to start-up around the middle of 2020. Hengli also operates another 3 PTA lines on the same site, each with a capacity of 2.2 million tonnes per annum, using Invista’s P7 PTA technology. This makes the Hengli site the largest PTA site in the world.
Mike Pickens, IPT President, commented, “I congratulate Hengli on the successful start-up. The achievement represents yet another major milestone for Hengli, and for Invista, it lifts us beyond the 30 million tonnes mark in terms of successful PTA startups. I am appreciative of the collaborative efforts of the Hengli and Invista commissioning teams. The successful start-up of Hengli’s fourth line again demonstrates Invista’s capability in the global PTA market.”
