CSPC mainly produces olefin and derivative products, supplying the domestic market as raw materials while providing customers with high quality service. As the one of the operating biggest single-site ethylene plant in China, CSPC's complex consists of 2 phases of projects with the ethylene capacity of 2,200 ktpa, and supplying more than 6 million tonnes of high quality products to the market every year. 

Phase I (Nanhai Project, C1)

CSPC Phase I (Nanhai Project, C1) started commercial operation in early 2006. C1 includes 11 major process units, utilities, storage and shipping facilities, as well as environmental protection facilities. It adopts 13 international leading technologies including Shell's proprietary technologies and utilizes modern management systems and international standards in design, construction and operation. C1 has achieved 1 million tpa ethylene production capacity since 2012 and it has been supplying approximate 2.8 million tonnes petrochemical products to the market every year.

CSPC Phase 2 project (C2)

CSPC Phase 2 (C2) started up in April 2018, including an ongoing project to build an ethylene cracker with 1.2 million tpa ethylene production capacity and multiple downstream derivatives units, which CSPC officially assumed ownership from CNOOC in November, 2016. The C2 expansion includes also SMPO/POD units. A total of 17 domestic and international industry-leading technologies including Shell's proprietary OMEGA, SMPO and Polyols technologies are applied to C2 project. This increases the volume and diversity of CSPC's high quality product range, as well as enhances overall energy efficiency.
