Invista’s technology and licensing group, Invista Performance Technologies (IPT), and Hengli Petrochemical (Hengli) have reached agreement for the licensing of Invista’s latest purified terephthalic acid (PTA) process technology for Hengli’s fifth PTA line. Invista’s latest industry-leading PTA technology is available as a licence package from IPT.

Hengli’s first three PTA lines, with a combined operating capacity of 6.6 million metric tonnes per year, the first of which began operation in 2012, utilise Invista’s P7 technology. This new line and the fourth line under construction, will utilise Invista’s P8 PTA technology at a scale of 2.5 million metric tonnes per year and include Invista’s proprietary R2R technology to recover Benzoic Acid, as co-product, from an oxidation waste stream.

“This is further demonstration of the PTA industry’s recognition of Invista’s industry-leading P8 technology designed to create long term value for our customers. I look forward to yet another successful collaboration between Hengli and IPT to achieve a fast track project,” Mike Pickens, IPT president said in a press release by Invista. (GK)
