On July 14, 2025, at the construction site of PetroChina Guangxi Petrochemical Company located in the China-Malaysia Qinzhou Industrial Park, the 1.2 million tons/year ethylene unit achieved a high-quality, high-standard intermediate handover after the quality assessment report was read out. Representatives from the construction, receiving, general contracting, construction, and supervision units signed the intermediate handover certificate, marking the full completion of PetroChina Guangxi Petrochemical's integrated refining and chemical transformation and upgrading project. It is understood that the project has a total investment of 30.5 billion yuan, covering an area of ​​over 4,400 mu, and is a major project in the national petrochemical industry planning layout. It is also a key project for building the Western Land-Sea New Corridor and participating in RCEP international competition. After completion and commissioning, the project will strongly promote PetroChina Guangxi Petrochemical Company's transformation from a "fuel-type" refinery to a "chemical products and organic materials-type" petrochemical enterprise, fill the gap in the region's high-end chemical new materials industry, meet the market demand along the Western Land-Sea New Corridor, and help Guangxi build a trillion-yuan-level green chemical new materials industrial cluster facing ASEAN. Since construction began in July 2023, the participating units have overcome a series of key and difficult problems and set many industry records, including building the world's largest diesel adsorption separation unit, building Asia's largest chemical rainwater and emergency pool, and realizing the recycling of construction water.

On October 30, 2025, the first batch of chemical products from the China National Petroleum Corporation (CNPC) Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project were officially shipped out, marking the full completion and commissioning of this major national project with a total investment of over 30 billion yuan (RMB). As a key project of CNPC's "14th Five-Year Plan," this project not only ended the history of Southwest China's long-term reliance on imports for high-end chemical raw materials, but also set a benchmark for the transformation and upgrading of the petrochemical industry with its "two-year construction period and zero accidents" speed.In the Qinzhou Port Economic and Technological Development Zone of Guangxi, tower cranes stand tall across the 300-hectare factory area, crisscrossed by silver pipelines. At 9:45 a.m. that day, as Li Congjia, Deputy Director of the China-Malaysia Qinzhou Industrial Park Management Committee, Tian Wenjun, Deputy General Manager of China National Petroleum Corporation Guangxi Petrochemical Company, and Zhang Zhongchen, Deputy General Manager of China National Petroleum Corporation South China Chemical Sales Company, pressed the start button, eight heavy trucks loaded with high-end chemical raw materials such as polyethylene and polypropylene slowly drove out. "This is not only a milestone for Guangxi Petrochemical, but also a historic leap for the petrochemical industry in Southwest China," said Tian Wenjun, Deputy General Manager of China National Petroleum Corporation Guangxi Petrochemical Company, at the scene. He explained that after the project reaches full production capacity, it will be able to produce 1.2 million tons of ethylene annually, with 16 sets of production units, converting 50% of the fuel used in traditional oil refineries into chemical products. Behind this transformation lies a breakthrough in overcoming the industrial predicament of "more oil than chemicals." Data shows that China's self-sufficiency rate for high-end chemical materials is less than 40%, and some high-end polyolefins and elastomers have long relied on imports. China National Petroleum Corporation's Guangxi Petrochemical Company has built the world's first diesel adsorption separation unit, converting heavy components in crude oil into high-value-added chemical raw materials, increasing raw material utilization by 15 percentage points. "It's like turning 'black gold' into 'white gold' in the same workshop," the project's technical leader aptly described.The project, spanning two years and encompassing both typhoon and rainy seasons, saw the construction team set numerous industry records. Employing a modular construction model of "one site + N factories," large equipment was prefabricated off-site before being assembled as a whole, effectively reducing overlapping operations and improving construction efficiency. In the 9-kilometer-long utility tunnel construction area, the traditional on-site single-column, single-beam installation method was completely overturned. "We assembled the utility tunnel into modular units in the prefabrication yard and then transported them to the site for assembly, which not only reduced a significant amount of high-altitude work but also improved construction efficiency," explained Xu Jianshu, the project management manager. Through factory prefabrication and modular construction, the construction team transferred most of the construction processes to paved surfaces or prefabrication yards, reducing the occupation of on-site roads and land, and minimizing the impact of construction on the surrounding environment, becoming a typical example of civilized construction.At Qinzhou Port, 30 kilometers from the factory, containers loaded with polyethylene granules are being shipped out via the Western Land-Sea New Corridor. Zhang Zhongchen, Deputy General Manager of South China Chemical Sales Company, explained, "Our products radiate throughout the Southwest and South China economic circles, enabling automobile factories in the Southwest to use locally produced high-end automotive plastics, and allowing Southeast Asian customers to place orders simultaneously." This radiating effect is already evident: Hengyi Petrochemical plans to invest an additional 5 billion yuan in Qinzhou to build a modified materials base; Sun Yat-sen University, in conjunction with Guangxi Petrochemical, is jointly building a green chemical research institute, which is expected to incubate 30 technology-based SMEs within five years. Data from the China-Malaysia Industrial Park Management Committee shows that the project has created 8,000 new local jobs and is expected to boost regional GDP growth by 1.2 percentage points by 2025.The transformation of China National Petroleum Corporation (CNPC) Guangxi Petrochemical Company reflects the deep-seated logic of the coordinated development of the Guangdong-Hong Kong-Macao Greater Bay Area and the Beibu Gulf city cluster. Relying on the Western Land-Sea New Corridor, Qinzhou is transforming from a former border fishing port into an international gateway port, and CNPC Guangxi Petrochemical Company's integrated refining and chemical transformation and upgrading project acts as a powerful heart, injecting surging momentum into the regional economic cycle. As the morning whistles of cargo ships and the evening birds fly over the factory area, a modern industrial landscape of "green mountains and clear waters are invaluable assets" is slowly unfolding on the shores of the South China Sea.

As PetroChina marks its 75th anniversary, the 300,000-ton-per-year high-density polyethylene (HDPE) unit at the Guangxi Petrochemical complex has recently produced on-spec product. This marks the commissioning of the first large-scale chemical unit within the Guangxi Petrochemical refining-chemical integration transformation and upgrade project—a key initiative for PetroChina. Comprising 16 chemical units—including a 1.2-million-ton-per-year ethylene unit—the project epitomizes PetroChina’s efforts to accelerate its move toward the higher end of the industrial value chain and advance high-quality, green, and low-carbon development.

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.

On May 10, Guangxi Petrochemical announced a significant achievement: the successful production of GPPS-550N, a high-quality, optical-grade polystyrene developed entirely in-house. This milestone marks an original breakthrough for the company in the field of high-end optical-grade chemical materials and injects strong momentum into achieving self-reliance and control within the domestic optical materials supply chain. At 9:00 AM on May 8, the 300,000-ton-per-year polystyrene unit at Guangxi Petrochemical began the process of switching production line grades. Leveraging the unit's process system, the technical team identified key process control points and precise additive dosages, monitored polymerization reaction status and equipment loads in real-time, closely coordinated with laboratory analysis data, and dynamically fine-tuned process parameters to ensure stable and controlled production throughout the process. Following 40 hours of continuous, intensive effort and precise adjustments, the unit successfully produced compliant material that was routed to the dedicated product silo. This marked the achievement of stable, mass production of the company's first batch of optical-grade GPPS-550N, with all key performance indicators meeting standards on the first attempt. GPPS-550N is a specialized, highly transparent material with a neutral (white) base tone. Benchmarked against top-tier industry grades, it boasts outstanding advantages—such as high light transmittance, superior thermal stability, and excellent safety compliance—fully meeting the technical requirements for high-end optical-grade products.

This successful achievement of mass production fills a gap in Guangxi Petrochemical’s high-end rubber production portfolio. After six months of intensive technical development, the company’s technical team successfully transitioned from initial trial production to full-load mass production. By leveraging customer feedback, they precisely optimized the product's molecular structure to meet the specific processing requirements of downstream manufacturers. They also overcame technical challenges and completed systematic upgrades to key equipment, laying a solid foundation for subsequent large-scale industrial production. Currently, Guangxi Petrochemical’s SSBR unit is fully capable of producing chain-end functionalized rubber at maximum capacity, and the SSBR2055DF2 grade is steadily entering the supply chain evaluation systems of leading domestic tire manufacturers.

This year marks the first year of integrated production and operations for Guangxi Petrochemical. As a major integrated refining and chemical base in Southwest China—boasting a refining capacity of ten million tons and an ethylene capacity of one million tons—the company faced severe challenges to its steady operation right from the start. It contended with multiple pressures, including significant volatility in international crude oil prices, ongoing adjustments to import pricing rules, and rigid cost increases in logistics and essential chemical agents. In response to this complex market environment, Guangxi Petrochemical adopted a holistic approach covering four key dimensions: feedstock procurement, production operations, product mix, and cost control. The company implemented 286 specific measures—categorized into six major groups and 46 initiatives—to enhance quality and efficiency, thereby establishing a lean management system that spans the entire value chain. Through synergistic value-chain integration, coordinated efforts across production, R&D, and sales, and company-wide cost control and value creation, the enterprise exceeded its interim operational targets. Through concrete action and tangible results, it has forged a new path of high-quality development, achieving steady breakthroughs and growth despite adverse conditions.Raw material costs are the lifeblood of refining and chemical enterprises, as well as a critical lever for hedging market risks and unlocking profit potential. Addressing the operational reality of relying on external markets for both raw materials and product sales, Guangxi Petrochemical broke down departmental silos to establish a cross-functional market analysis task force. This team coordinates marketing and production departments to jointly assess market trends, continuously expand crude oil procurement channels, and diversify the crude oil mix—increasing the variety of procured crude types to 75. This diversified sourcing strategy effectively hedges against price spikes in any single crude variety and secures a stable, reasonably priced raw material supply. "Crude oil procurement cannot be based on unit price alone; it requires comprehensive calculations factoring in pricing formulas, shipping cycles, and unit compatibility, alongside a multi-perspective, flexible allocation strategy," said Guo Chunfeng of the Marketing and Logistics Department. The company implemented daily analysis and weekly review mechanisms to track crude oil price trends in real-time, strictly controlling procurement costs at the source to maximize efficiency. Procurement practices have shifted from a simple "race to the bottom" on price to a "total cost" approach, enabling scientific, refined, and dynamic management. The Production Operations Department coordinates across various refining units to continuously upgrade ethylene feedstocks toward lighter and higher-quality grades, establishing channels for material exchange between units and process sections. Through a series of process innovations—such as upgrading etherified gasoline, increasing yields of light naphtha and raffinate, substituting straight-run naphtha with catalytic gasoline, and optimizing fuel gas network composition—the company fully utilizes low-value or idle internal materials to consistently supply high-quality feedstock to the ethylene unit. By implementing a closed-loop recovery and reuse system for by-products, Guangxi Petrochemical saves tens of millions of yuan in external procurement costs annually, effectively absorbing the pressure of rising upstream raw material prices while simultaneously reducing costs, improving quality, and increasing efficiency. With the coordinated support of the Group, Guangxi Petrochemical has deepened upstream-downstream and internal-external collaboration, securing seven material exchange agreements and strengthening its land-sea intermodal supply network; since the beginning of the year, the company has procured nearly 180,000 tons of high-quality naphtha. At the same time, the company has constructed its largest dedicated 10,000-ton class naphtha loading and unloading berth; this addresses the previous shortfall in handling large raw-material vessels and secures a smooth channel for importing high-quality feedstocks, thereby laying a solid infrastructure foundation for the facility to achieve stable, high-load production and enhanced efficiency.Faced with the industry-wide challenge of rising costs and shrinking profit margins on low-end products, Guangxi Petrochemical has steadfastly adhered to the philosophy that "major stability yields major benefits." Grounding its operations in the safe, stable, and optimal performance of its units, the company has tackled the dilemma of "increased output without increased revenue" by upgrading its product mix toward high-end offerings, thereby maximizing profitability. The company’s technical team focused on the challenges of processing diverse crude oil feedstocks, successfully resolving 31 operational bottlenecks. They completed full-load performance testing for nine core refining and chemical units—including the ethylene unit—significantly enhancing the facilities' compatibility with various crude oil types. By achieving stable, large-scale production, the company diluted unit processing costs and secured a solid foundation for profitability through operational stability. Guangxi Petrochemical established a dedicated task force to monitor price fluctuations in chemical products and implemented a "one-product, one-strategy" differentiated production scheduling mechanism. The company proactively reduced capacity for low-efficiency and slow-moving basic chemicals while strategically allocating high-quality feedstocks to boost the output of high-end new materials. Leveraging its in-house R&D and innovation platforms, the company successfully mass-produced 13 types of new chemical materials in the first seven months of the year, steadily enhancing the market competitiveness of product lines such as rubber and polyolefins. Capitalizing on the strategic location of the New International Land-Sea Trade Corridor, Guangxi Petrochemical aggressively expanded into overseas markets. It achieved its first exports of high-end rubber and specialized polypropylene materials, precisely targeting the robust demand for high-end chemical materials within the ASEAN region. "Competition for low-end chemical products in the domestic market is fierce, and profit margins are razor-thin; meanwhile, demand for high-end new materials in the ASEAN region continues to grow, offering significant potential for deep market development," said Ren Gangxing, a senior supervisor in the Marketing and Logistics Department. This synergistic dual-market strategy effectively hedges against rising upstream costs and establishes a new buffer zone for profit growth.As the lead enterprise for the Qinzhou Petrochemical Industrial Park's value chain, Guangxi Petrochemical has leveraged its role as an industry leader to explore new paths for integrated park operations. By fostering supply chain synergy to cut costs and revitalizing resources to generate value, the company has pioneered a new operational model. It anticipated industry trends and commissioned a gas-phase ethylene export pipeline within the park, enabling direct material supply and interconnection between upstream and downstream units. With a cumulative pipeline throughput of 49,400 tons of ethylene, the company eliminated costs associated with loading, unloading, transshipment, and long-distance transport, while effectively avoiding issues such as rising logistics costs and material losses, thereby establishing itself as a benchmark for trading-oriented enterprises. Precision financial control empowers operations, driving quality and efficiency through a dual-pronged approach. The company has deepened refined financial management and systematically revitalized idle assets—such as spent catalysts and packaging materials—in compliance with regulations. In the first seven months of this year, the disposal of spent catalysts, additives, and adsorbents generated over 50 million yuan in additional revenue. Simultaneously, the company optimized its capital allocation model by adjusting settlement cycles for crude oil procurement and logistics payments, thereby continuously reducing financial operating costs. This combination of increasing external revenue and cutting internal costs has helped offset the operational pressure caused by rising raw material prices. Adhering to a philosophy of "tightening the belt," Guangxi Petrochemical has integrated cost control across the entire production and operation chain, ensuring that responsibility for quality and efficiency improvements is firmly established at every level and position. The Finance and Production Operations departments spearheaded the creation of a comprehensive cost assessment system. This system breaks down key performance indicators—covering processes from crude oil procurement and production to unit maintenance—into specific targets for individual departments, units, and teams, ensuring all-encompassing cost control with no blind spots. The equipment management department has focused on lean maintenance management, strictly controlling unnecessary expenditures by optimizing procurement plans for maintenance materials and streamlining construction workflows. From management-level cross-enterprise resource coordination to frontline teams recovering by-products through technical upgrades, the drive for quality and efficiency has evolved from a task for a single department into a collective effort involving the entire workforce across all operational areas. Diversified sourcing of 75 crude oil varieties has fortified the foundation of supply security; the launch of 13 new material products has ignited growth momentum; and the pipeline transport of 62,200 tons of ethylene has driven cost reductions across the value chain. These impressive figures bear witness to the enterprising spirit of the entire workforce at Guangxi Petrochemical as they confront challenges head-on, proactively drive transformation, and tackle tough tasks with pragmatic action.
