On October 30, 2025, the Guangxi Petrochemical Ethylene Project—a major initiative under the national petrochemical industry layout plan and a key project of the Group Company’s "14th Five-Year Plan"—successfully commenced production on its first attempt at Qinzhou Port, Guangxi, with the first batch of qualified chemical products shipped out. Coming at the critical juncture of concluding the "14th Five-Year Plan," this project not only marks the completion and commissioning of the largest million-ton-scale ethylene project in Southwest my country but also injects powerful momentum into the petrochemical industry's shift from "scale dependency" toward a path of high-quality development defined by "quality breakthroughs."
With a total investment exceeding 30 billion yuan, the project set multiple industry records during the two-year period from its commencement in July 2023 to its mechanical completion in July 2025. Notably, the world's largest diesel adsorption separation unit—utilizing "molecular engineering" concepts—achieved a feedstock utilization efficiency more than 15% higher than traditional processes, effectively addressing the structural imbalance of "high fuel output versus low chemical output" in my country's petrochemical industry. The project also saw the construction of the first units utilizing PetroChina's proprietary technologies for 80,000-ton/year SBS and 120,000-ton/year functionalized solution-polymerized styrene-butadiene rubber (SSBR), alongside the deployment of the world's largest ethylene refrigeration compressor motor featuring seamless dual-inverter switching. The concentrated implementation of these "world-first" and "domestic-first" achievements signals the further maturation of my country's independent petrochemical technology system, laying a solid foundation for the domestic substitution of high-end chemical equipment during the "15th Five-Year Plan" period.
As the Group Company's benchmark project for transforming a standalone refinery into an integrated refining-chemical complex, the Guangxi Petrochemical Ethylene Project comprises 14 chemical units (centered around a 1.2-million-ton/year ethylene unit), two refining units, and associated utility and auxiliary facilities. Upon commissioning, the project will reduce annual fuel production by 3.49 million tons while increasing chemical product output by 3.06 million tons; products such as high-end polyolefins, functionalized rubber, high-end film materials, and pipe materials will help bridge domestic supply gaps. Furthermore, the project’s additional electricity needs are met entirely by green power, and its energy consumption metrics surpass national benchmark standards. By establishing a "resource-product-green application" circular chain, the project contributes to the steady advancement of my country's "Dual Carbon" goals.
In terms of regional development, this project drives the transformation of Guangxi’s industrial landscape from basic chemicals to high-end chemical new materials. Leveraging the New International Land-Sea Trade Corridor, the products can reach markets across Southwest China, South China, and ASEAN, helping to build a trillion-yuan-level green chemical new materials industrial cluster oriented toward ASEAN. By stimulating the growth of downstream sectors—such as packaging, construction materials, and automotive manufacturing—the project fosters an industrial ecosystem characterized by "leading-enterprise-driven cluster development." It overcomes the supply bottleneck for high-end chemical raw materials in Southwest China while expanding into overseas markets by capitalizing on the benefits of the Regional Comprehensive Economic Partnership (RCEP), thereby providing vital support for the new development pattern of mutually reinforcing domestic and international economic circulations.
