30.4 billion! PetroChina Guangxi Petrochemical 1.2 million Ton Ethylene Plant Successfully Start-up

At 14:38 on October 26, 2025, the 1.2 million-ton/year ethylene plant of PetroChina Guangxi Petrochemical Company was officially put into operation. After 12 hours and 3 minutes, qualified products were produced at 2:41 on the 27th, achieving a successful start-up. This milestone event marks the complete completion of the strategic transformation of Guangxi Petrochemical from a traditional "fuel-type" refinery to a modern "chemical products and organic materials-type" refining and chemical integration enterprise.

From the perspective of industrial layout, the successful commissioning of the project has a profound impact on the petrochemical industry in Southwest China. On the one hand, it breaks the situation that high-end chemical products in Southwest China rely on external supply for a long time. On the other hand, it will form a new industrial ecology of "leading and cluster development", which will provide a strong driving force for the improvement and upgrading of the regional petrochemical industry chain.

the ethylene plant is contracted by Huanqiu Engineering Co., Ltd., and the core technology adopts the large-scale ethylene complete set of technology with independent intellectual property rights of PetroChina, which reflects the independent innovation ability of petrochemical engineering technology in China. From the perspective of production capacity structure, the plant planning is scientific and reasonable: annual output of 1.2 million tons of polymer-grade ethylene, 616000 tons of polymer-grade propylene, 400000 tons of hydrogenated gasoline and 35000 tons of styrene, and by-product production of more than 20 kinds of chemical raw materials, products and semi-finished products such as hydrogen, cracked carbon 5, carbon 9 and cracked fuel.

After the plant is put into operation, the product structure of Guangxi Petrochemical Company will be significantly optimized: the annual output of oil products will be reduced by 3.49 million tons, and the output of chemical products will be increased by 3.06 million tons. This adjustment of "oil reduction and increase" coincides with the current market pattern in which the domestic refined oil market tends to be saturated and the supply of high-end chemicals is insufficient. It is particularly noteworthy that the high-end membrane materials, pipe materials and other products produced by the device will directly fill the domestic supply gap, effectively alleviating the long-standing structural contradiction of "less oil and insufficient high-end" in my country's petrochemical industry.

as a major project in the planning and layout of the national petrochemical industry and a key project of PetroChina's "14th Five-Year Plan", the total investment of Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project reached 30.459 billion billion yuan. The project takes the 1.2 million-ton/year ethylene plant as the core, and supports the construction of 14 sets of chemical plants, 2 sets of oil refining plants and public and auxiliary facilities, which will be fully completed on July 14, 2025.

In the refining sector, the project relies on the existing 10 million tons/year refining capacity and 30 sets of main production units, the new 2 million tons/year diesel adsorption dearomatization unit and 400000 tons/year carbon two recovery unit, while the two sets of main production units to achieve capacity optimization. The chemical sector has newly built 14 sets of chemical main units, including 1.2 million tons/year ethylene unit, 550000 tons/year pyrolysis gasoline hydrogenation unit/styrene extraction combined unit, 180000 tons/year butadiene extraction unit and other key facilities. This integrated configuration of refining and chemical industry can realize the mutual supply of raw materials, optimize the utilization of resources and maximize economic benefits.

as the first benchmark project of PetroChina to transform from oil refining to refining and chemical integration, the successful transformation of Guangxi Petrochemical has important demonstration significance. After the project is fully put into operation, it will fill the gap of high-end chemical new materials industry in Southwest China, and promote the transformation of Guangxi from basic chemical industry to high-end chemical new materials industry.

From the perspective of market radiation, the project relies on the location advantage of the new land and sea channel in the west, which can directly meet the market demand of Southwest, South China and ASEAN. This is not only a key measure to implement the national "One Belt One Road" initiative and build a new land-sea channel in the western region, but also will help Guangxi build a trillion-level green chemical new material industry cluster facing ASEAN.

The driving effect on the downstream industry can not be ignored. The abundant supply of chemical raw materials will strongly support the development of packaging, building materials, automobiles and other industries, forming a complete industrial ecological chain. For chemical traders and downstream enterprises, this means that the supply of raw materials is more stable, the procurement radius is shortened, and the logistics cost is reduced, which will significantly enhance the competitiveness of the regional industrial chain.
