Chinese petrochemical firm commissions second PTA unit

China Prosperity (Jiangyin) Petrochemical Co. Ltd., a wholly owned subsidiary of Jiangyin Chengxing Industrial Group Co. Ltd., has commissioned a second purified terephthalic acid (PTA) unit at its petrochemical production plant in Shizhuang Petrochemical Industrial Zone in Jiangyin City, Jiangsu Province, China.

Equipped with Invista Performance Technologies’ (IPT) proprietary E2R, Solvent Interchange, and R2R PTA process technologies, the 2.2 million tonne/year line began producing on-spec PTA within 24 hr of its Mar. 14 startup, Invista said.

The second PTA unit joins China Prosperity’s existing 600,000-tpy PTA unit at the site, which began operating in January 2011 and also is equipped with IPT’s PTA technologies, the technology licensor said.

China Prosperity, which invested 6.55 billion yuan renminbi ($1 billion) in the PTA expansion, began construction on the PTA expansion project on Dec. 5, 2013, with trial operations of the unit at that time scheduled to start by October 2015, according to December 2013 release from the government of Jiangyin City.

Last month, Chengxing signed a syndicated loan in the amount of 2.9 billion yuan renminbi ($446.7 million) with a consortium of seven banks to further its investments into expanding operations in the region, Jiangyin City’s government said in a Mar. 29 release.
