Hengli Petrochemical’s fourth purified terephthalic acid (PTA) line utilising Invista’s P8 Process Technology has succeeded in meeting all performance guarantees. The line with 2.5 million tonnes per annum capacity is located in Changxing Island. Hengli’s fourth PTA line was executed in record time of 22 months from engineering kick-off meeting to start-up.

Hengli’s fourth PTA line of 2.5 million tonnes per annum capacity, located in Changxing Island, Dalian City, Liaoning Province, utilising Invista’s P8 PTA technology with industry leading variable cost, capital productivity and environmental performance, came online on January 8, 2020. This PTA line also produces benzoic acid as co-product, utilising Invista’s proprietary R2R technology.

Hengli’s fourth PTA line was executed in record time of 22 months from engineering kick-off meeting to start-up. Both parties demonstrated extraordinary commitment under the difficult circumstances. Invista’s commissioning team provided Hengli with onsite and remote technical support to optimise the plant performance in quick time.

Adam Sackett, Invista Performance Technologies (IPT) vice president PTA, commented, “This is the latest in a series of successful collaborations between the teams of both companies and I congratulate Hengli on achieving this significant milestone on Line 4. Whilst Hengli Line 4 has already demonstrated industry leading variable cost performance, we will continue to support Hengli to further optimise the plant.”

Chen Xinhua, vice chairman of Hengli, expressed his trust in Invista’s PTA technology, saying, “We are honoured to choose Invista’s world class P8 PTA technology. We appreciate Invista’s excellent support throughout the whole project lifecycle. We look forward to ongoing cooperation with Invista in the future.”
