Tongkun Group Co. Ltd. subsidiary Jiaxing Petrochemical Co. Ltd. (JPCL) has commissioned a second purified terephthalic acid (PTA) unit at its petrochemical production plant at Zhejiang Zhapu Industrial Park in Jiaxing Port Area, Zhejiang Province, China.
Equipped with Invista Performance Technologies’ (IPT) latest P8 proprietary PTA process technology, the first reaction train of the new PTA line reached its fully designed rate in 10 days after introduction of first feedstock, IPT said.
While IPT did not specify capacity of the new line, the new PTA plant previously was slated to have a nameplate capacity of 1.2 million tonnes/year, Tongkun said in a 2013 regulatory filing on the project.
In addition to the new PTA plant, JPCL operates a 1.67 million-tpy PTA line at the site that, commissioned in 2012, also is equipped with IPT’s process technology, according to a PTA reference list posted to the service company’s web site.
Start-up of the second PTA plant marks the first commercial deployment of P8 PTA technology, IPT said.
