The two other bidders for the project are South Korea's Daelim Industrial Companyand Italy's Snamprogetti. The client, National Petrochemical Company (NPC), has not yet officially selected a preferred bidder. The plant's output will comprise 200,000 t/y of general-purpose polystyrene and high-impact polystyrene and 50,000 t/y of expandable polystyrene.

PPC already has a 600,000-t/y styrene plant, built by Snamprogetti. Propane and butane units, of 980,000 t/y and 570,000 t/y respectively, are also planned at the complex, which will provide feedstock for downstream polymer units, electrical industries, insulation polystyrene, adhesives, textiles and disposable products.
