C3 Petrochemicals plans to build a propane dehydrogenation (PDH) plant near Alvin, Texas, to produce polymer-grade propylene (PGP) and chemical-grade propylene (CGP), according to an air quality permit application that the company filed this month with the US Environmental Protection Agency (EPA). The plant will be built on the grounds of Ascend Performance Materials’ Chocolate Bayou Chemical Manufacturing Complex. Construction of the PDH plant will begin in January 2014, with start-up scheduled for Q4 2015, subject to approvals. The PDH unit will use propane as its feedstock. As part of the PDH process, ethane, ethylene and methane also will be produced.
Ascend Performance Materials is a private nylon 6,6 manufacturer owned by SK Capital Partners, a private investment firm based in New York City.
