INVISTAs technology and licensing group, INVISTA Performance Technologies (IPT), and Hengli Petrochemical (Dalian) Co., Ltd. (Hengli) have reached agreement for the licensing of INVISTAs latest purified terephthalic acid (PTA) process technology for Henglis fifth PTA line. Henglis 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, utilize INVISTAs P7 technology. This new line and the fourth line under construction, will utilize INVISTAs P8 PTA technology at a scale of 2.5 million metric tonnes per year and include INVISTAs proprietary R2R technology to recover Benzoic Acid, as co-product, from an oxidation waste stream.
