en.Wedoany.com Reported - PetroChina Dushanzi Petrochemical Company's Tarim 1.2 Million Tons/Year Phase II Ethylene and Supporting Green Low-Carbon Demonstration Project began feeding materials at 9:17 on July 15, and produced qualified ethylene at 4:58 on July 16, achieving a successful one-time startup. As China's first full-chain refining and chemical demonstration project practicing green and low-carbon concepts, and a key project under the national petrochemical industry planning and layout, it will provide replicable and scalable technical solutions for the low-carbon transformation of Sinopec and the broader industry.
Located in the Korla Shangku Industrial Park in Xinjiang—the only one among China's first batch of national-level zero-carbon industrial parks primarily focused on high-energy-consuming petrochemical industries—the project has built the world's first demonstration base for carbon recycling of ethylene cracking furnace flue gas, achieving an annual carbon reduction of 1.37 million tons. The project establishes a "photovoltaic + chemical" green circular ecosystem, consuming 1 billion kWh of photovoltaic clean electricity annually from the Tarim Oilfield. It has built China's first domestically developed electric drive system for ethylene three machines, achieving a technological leap from "thermal drive" to "electric direct drive." Utilizing China's pioneering ultra-low concentration carbon dioxide integrated capture technology, it forms a full-chain low-carbon technology loop of "direct green power connection + carbon capture + blue hydrogen + blue ammonia + green fertilizer," with all carbon dioxide and by-product hydrogen recovered and reused.
Independent and controllable technology is the core highlight of this project. Among the 11 main production units, 10 adopt China's proprietary technologies, with 9 independently developed by PetroChina, and 5 technologies being applied for industrial scale-up for the first time. The overall localization rate of the project reaches 99%, with the ethylene unit essentially fully localized, and units such as pyrolysis gasoline hydrogenation and cis-polybutadiene rubber achieving a 100% localization rate. The large-scale extrusion pelletizing unit has achieved a breakthrough in domestic manufacturing. The overall terminal electrification rate of the plant is nearly double that of traditional ethylene plants, placing its energy utilization efficiency at the forefront of the industry.
According to reports, to address challenges such as the project's location on the edge of the Taklamakan Desert, frequent high temperatures and sandstorms, and insufficient supporting infrastructure, the project team implemented a "six-ization" construction model—including standardized design, modular construction, and intelligent management—completing the main mechanical completion in just 22 months, setting a new record for effective construction timelines for refining and chemical projects of similar scale in China.
After the project's commissioning, Dushanzi Petrochemical will become the only 3-million-ton-class ethylene production base in central and western China. The project will fill gaps in the new materials industry in southern Xinjiang, such as high-end polyolefins and synthetic rubber, drive the development of a downstream industrial cluster worth hundreds of billions of yuan, boost the GDP of the Bayingolin Mongol Autonomous Prefecture by 15%, create a large number of jobs, and inject industrial momentum into the region's high-quality development.
