PetroChina Dushanzi Petrochemical Company

The company focuses on crude oil refining, ethylene cracking, and production of downstream petrochemicals and chemicals. Its refining capacity stands at around 10 million tons per year, while ethylene capacity has expanded to over 3 million tons annually following the commercial operation of the Tarim Phase II project. Key products encompass fuels, polyolefins including polyethylene and polypropylene, synthetic rubbers like butadiene rubber, fertilizers, and various resins and chemicals, serving both domestic markets in Xinjiang and exports to Central Asia.

Established in 1936 as one of the origins of China's petroleum industry, it functions as a strategic hub for oil and gas processing, storage, and transmission, particularly handling crude imports from Kazakhstan. The company emphasizes sustainability through green technologies such as renewable electricity integration, carbon capture from ethylene processes, and low-carbon demonstration projects. As a key player in China's western petrochemical sector, it helps balance the nation's ethylene production capacity away from coastal concentrations and supports regional industrial development and energy security.
