Petrochemicals

The nation's "big four" petrochemical enterprises, PetroChina, Sinopec, CNOOC and ChemChina, have a presence in Tianjin.

The city produces 11 categories and more than 2,000 varieties of petrochemical products including sodium carbonate, caustic soda, chlorine derivative products, raw salt, rubber, plastics and basic organic chemical products.

The city's 1-million-ton ethylene project is one of the largest facilities of its kind in China. Tianjin has formed a complete industry chain featuring oil exploitation, refining and production of ethylene and other chemicals.

In the first half of 2013, the city's Binhai petrochemical industry base reported a gross output of 166.53 billion yuan, which was up 3 percent year-on-year and accounted for 21.2 percent of the total output of the Binhai New Area.
