The general contracting project for the second-phase ethylene air separation plant with an annual capacity of 1.2 million tons at Dushanzi Petrochemical in Tarim has officially commenced construction

Thread Content

On the morning of December 20, 2024, the general contracting project for the second phase of the 1.2 million tons per year ethylene air separation unit at Tariem of Dushanbe Petrochemical Company officially commenced construction; slotting work was carried out in the cabinet room, marking the entry of the project into a new phase of actual construction. It is understood that CNPC’s Dushanzi Petrochemical Tarim Phase II ethylene project primarily involves separating ethane from natural gas, which is then used to produce ethylene through ethane cracking. The approved investment for this project amounts to 21.88 billion yuan. Leveraging the abundant oil and gas resources in the Tarim Basin, it will build 11 major production units, including one unit capable of producing 1.2 million tons of ethylene per year, two units capable of producing 450,000 tons of high-density polyethylene per year, and one unit capable of producing 300,000 tons of low-density polyethylene per year. The proportion of self-developed technology used in this project exceeds 99%, while the proportion of domestically produced equipment exceeds 98%.

Project Components: Ethylene plant, FDPE plant, LDPE plant (with EVA production capacity), PP plant, butadiene extraction plant, MTBE/butene-1 plant, cis-butadiene rubber plant, pyrolysis gasoline plant, aromatic extraction plant, as well as supporting utility systems, auxiliary production facilities, and storage and transportation facilities. Product portfolio: The main products include HDPE, LLDPE, LDPE, EVA, PP, butadiene rubber, MTBE, pyrolyzed C5, benzene, toluene, xylene, and pyrolyzed fuel oil; by-products include polyethylene wax, butadiene, C9+, etc. Project Progress: On November 30, 2024, the handover ceremony for the Public Auxiliary I Radioactive Source Repository of the Tarim Phase II Ethylene Project at Dushanbe Petrochemical Company was held at the project site, marking the completion of the handover of the first key unit of this project. On June 20, 2024, the second public announcement regarding the environmental impact assessment for the project modifications of Tarim’s 1.2 million tons per year Phase II ethylene project was issued. On May 26, 2024, the commissioning ceremony for the cracking furnace of the 1.2 million tons per year ethylene plant in the Tarim Phase II ethylene project of Dushanzi Petrochemical was held grandly at the pre-fabrication site of the cracking furnace. On December 21, 2023, the 1.2 million tons per year ethylene production project of Tarim Phase II at Dushanzi Petrochemical Company officially commenced construction. In October 2023, the second phase of the 1.2 million tons per year ethylene production project at Tarim, operated by Dushanbe Petrochemical Branch, was officially launched in the Shangku High-Tech Industrial Development Zone in Korla, in southern Xinjiang. On August 7, 2023, Dushanbe Petrochemical Company held a mobilization meeting for the construction of the second phase of the Tarim 1.2 million tons per year ethylene production project. On August 8, the official WeChat account of Dushanbe Petrochemical announced that the second phase of this ethylene project had been successfully launched. On April 26, 2023, the Korla government website published the second public notice regarding the environmental impact assessment for the second phase of Dushanzi Petrochemical Company’s Tarim 1.2 million tons per year ethylene production project.
