PetroChina Lanzhou Petrochemical Company is a regional branch of China National Petroleum Corporation (CNPC). Its predecessors, Lanzhou Refinery and Lanzhou Chemical Industry, were both key projects during China's First Five-Year Plan. Since commencing operations in 1958, it has generated over 20 billion yuan in profits and taxes, and has always been renowned for its high-quality products, advanced technology, extensive experience, skilled personnel, and efficient operations, earning it the reputation as the "cradle" of China's refining and petrochemical industries, respectively. Lanzhou Petrochemical Company integrates oil refining, chemical, and fertilizer production, and is the largest petrochemical enterprise in western China. The company has a crude oil primary processing capacity of 10.5 million tons per year and corresponding secondary processing capabilities, producing over 400 kinds of petrochemical products, including gasoline, diesel, kerosene, lubricating oil, catalysts, and synthetic rubber. It is one of the enterprises in my country with a relatively complete range of petrochemical products. Its petroleum products, synthetic resins, synthetic rubber, and catalysts enjoy a good reputation in domestic and international markets. Currently, Lanzhou Petrochemical Company is one of the three major catalytic cracking catalyst production bases in China. The national Western Development Strategy has brought tremendous development opportunities to Lanzhou Petrochemical Company. China National Petroleum Corporation (CNPC) timely proposed the strategic concept of building a large-scale oil refining and chemical base in Lanzhou, and designated Lanzhou Petrochemical Company as a key focus of its investment and development in the west. In the 10th Five-Year Plan and the 2015 long-term vision, it was planned and constructed as one of the four major oil refining and chemical production bases. From the 10th Five-Year Plan to 2015, Lanzhou Petrochemical Company will follow a three-step approach to promote its overall development, ultimately building itself into a large-scale petrochemical enterprise with advanced technology, strong competitiveness, and significant profitability, making a greater contribution to the value enhancement of CNPC and the country's economic development. Contact Person:Bepa ZhuMobile:+8618136850665WhatsApp/WeChat:+8618136850665E-mail:sales4@ascent-chem.comE-mail:2146177559@qq.com

Winning the "14th Five-Year Plan" and Striving for High-Quality Development: During the "14th Five-Year Plan" period, Lanzhou Petrochemical's 185 key projects have blossomed across multiple sectors, driving continuous growth in digital coverage, significantly accelerating new product development, reducing carbon emission intensity year by year, and rapidly accumulating new-quality productivity, creating a new growth pole for transformation and upgrading. On November 24, 2025, the AI ​​rubber inspection system of Lanzhou Petrochemical's newly built 35,000-ton/year special nitrile rubber production line was operating efficiently, completing the appearance quality inspection of a rubber product in just 10 seconds. On the same day, a ship carrying Lanzhou Petrochemical's high-end nitrile rubber products arrived at the Port of Rotterdam, Netherlands, and was about to be delivered to European customers. During the "14th Five-Year Plan" period, Lanzhou Petrochemical vigorously developed new-quality productivity and laid out emerging industries, investing nearly 7 billion yuan and spawning 185 new projects, covering multiple fields such as digital transformation, development of new chemical materials, green environmental protection, and industrial chain extension. The support of these key projects has driven profound changes in the company's development model, industrial structure, and competitive advantages. Lanzhou Petrochemical, this old refining and chemical enterprise, is rapidly shedding the inertia of its traditional production model, shifting gears, and accelerating its transformation and upgrading.In September of this year, the Ministry of Industry and Information Technology announced the list of outstanding smart factories for 2025, and Lanzhou Petrochemical was among them, entering the "first tier" of digital transformation for domestic refining and chemical enterprises. This transformation began with precise strategic planning. In 2021, Lanzhou Petrochemical took the lead in piloting the digital transformation of the group's refining and chemical enterprises, using the newly built ethane-to-ethylene project of Yulin Chemical Co., Ltd. as a "test field," planning and promoting the construction of intelligent factories and projects simultaneously. The vast Mu Us Desert has thus sown the "seeds" of full-element digitalization. The initial project plan involved an investment of over 80 million yuan in digitalization, with subsequent investments gradually increasing. It integrated cutting-edge technologies such as cloud platforms, edge computing, 5G, and artificial intelligence to build the first intelligent plant across the entire ethylene business chain in China. "This is not just a simple process innovation, but also a practice of proactively embracing digitalization and exploring new development paths in project construction," stated Li Wei, General Manager and Chief Engineer of Yulin Chemical Co., Ltd. This successful practice provided a new blueprint for Lanzhou Petrochemical's subsequent transformation. In the following years, Lanzhou Petrochemical took the lead: in 2023, it was among the first to launch the group's information technology enhancement project; in 2024, it spearheaded the implementation of the Kunlun large-scale model scenario; it was the first to overcome the technical difficulties of the Kunlun MES statistical balancing module; a three-level digital empowerment system of "company-factory-workshop" was unveiled; and the application of digital technology gradually penetrated into multiple aspects such as equipment monitoring and data analysis, achieving a leap forward in three stages: "information technology enhancement—digital empowerment—intelligent development." Moving from single-point breakthroughs to systemic advancement, Lanzhou Petrochemical continues to unleash the value of digital empowerment: the digital coverage rate of its main business has jumped to 85%, the production stability rate has increased to over 99.8%, and the equipment fault diagnosis accuracy rate has reached 92%. Accompanied by an efficiency revolution of "digital + professional," Lanzhou Petrochemical has steadily embarked on a new track of digital and intelligent development.On May 20, 2022, exciting news arrived: the 35,000-ton/year special nitrile rubber unit, using technology with fully independent intellectual property rights, successfully started up on its first attempt! This marks the successful commissioning of a major key project in China National Petroleum Corporation's "14th Five-Year Plan" transformation and upgrading. From then on, Lanzhou Petrochemical's total nitrile rubber production capacity reached 100,000 tons/year, ranking second in the world and first in Asia. The products of this unit cover general and special series, encompassing more than 30 grades including low-nitrile, medium-nitrile, and high-nitrile rubbers. Even more encouragingly, in 2024, high-carboxyl-value nitrile butadiene rubber was successfully produced, breaking the foreign technological monopoly and finding widespread application in high-end fields such as automobiles, aerospace, and petroleum. This laid the foundation for Lanzhou Petrochemical to build a high-end synthetic rubber production base and lead industry upgrading. From leading and demonstrating the ethane-to-ethylene project to targeting the layout of high-end chemical new materials, Lanzhou Petrochemical has proactively stepped out of its comfort zone, focusing its attention on the top of the industrial chain, accelerating project construction, and achieving a new speed of transformation and upgrading. Over the past five years, relying on several high-end new material technology upgrades and capacity expansion projects, including the injection molding special resin of the 110,000-ton/year polypropylene unit, the development of metallocene products in the full-density polyethylene unit, and the gas phase reactor of the 300,000-ton/year polypropylene unit, Lanzhou Petrochemical has developed a total of 154 new products, 85 of which are first-time developments. The number of new product developments ranks among the top in China's petroleum refining and chemical new materials sector. It has gradually formed a multi-series of high-end new products, represented by medical and automotive polyolefin materials, metallocene polyethylene pipe materials, and ultra-high voltage cable insulation base materials, significantly improving the differentiation and high-end rate of its chemical products. This year, nitrile rubber and polypropylene product SP179 have successively broken into overseas markets, achieving breakthroughs in Europe and Africa, opening up new avenues for product efficiency enhancement, and further expanding the influence of China Petroleum's brand in the global market. Moving away from the traditional path of single-scale expansion, Lanzhou Petrochemical is focusing on upgrading its industrial chain, targeting a series of technology-intensive, high-value-added advantageous projects, gathering innovative resources, removing development bottlenecks, and generating a continuous stream of new productive forces. This clearly outlines a path of industrial upgrading and advancement from "following" to "keeping pace" and then to "leading" breakthroughs.In the summer of 2023, the site of the Lanzhou Petrochemical 3 million tons/year heavy oil catalytic cracking unit MIP Phase II renovation project was bustling with activity, sparks flying. This 22-year-old unit was undergoing the largest MIP technology renovation of its type nationwide. After the upgrade, the olefin content of catalytic gasoline decreased by 6 percentage points, and the octane rating increased by more than 0.5 units. This represents a milestone leap in gasoline quality, upgrading from China V to China VI B, injecting greener and more efficient power into countless vehicles. This is not only a radical green innovation aimed at internal improvement, but also a leap forward empowering the future. It allows Lanzhou Petrochemical's transformation path to simultaneously increase both its "green content" and "gold content," with every step imbued with the warmth of ecological civilization and the quality of corporate development. Over the past five years, while pursuing technological leadership and industrial upgrading, Lanzhou Petrochemical has consistently adhered to its green principles, investing over 2 billion yuan in more than 50 major environmental improvement projects, including boiler ultra-low emission technology upgrades, rainwater and sewage separation projects, oil and gas recovery, and high-energy-consuming motor upgrades, enhancing the sustainability of the company's green development. Lanzhou Petrochemical, aiming for cleaner production, has strengthened the tiered, circular, and reuse of water resources. Through the construction of pre-treatment facilities for wastewater from the No. 2 chemical plant and special nitrile rubber production lines, a 1080-ton/hour deep treatment and reuse unit for refinery wastewater has been built and put into operation. The company has also improved its greening water supply network, achieving deep wastewater reuse and saving over 5 million tons of water and reducing emissions annually. These continuous green innovations have not only given Lanzhou Petrochemical a "new green look," but also ensured that every step of its transformation and upgrading is grounded in green development and on the path to high quality. During the 14th Five-Year Plan period, Lanzhou Petrochemical's carbon emission intensity per 10,000 yuan of output value decreased year by year, with a reduction of 12.7%. Emissions of air pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, and VOCs decreased by 93.40%, 27.97%, 72.29%, and 19.57% respectively compared to the 13th Five-Year Plan period, creating a new picture of "factory in the forest, industry in the green." Today, as the "ballast" of Northwest China's industrial economy, Lanzhou Petrochemical continues its relentless progress, forging ahead with a pragmatic approach and outlining a new development blueprint for "rebuilding Lanzhou Petrochemical and creating new corporate glories."

Lanzhou Petrochemical is the first large-scale refining base in West China to be constructed with a 10Mt/a refining capacity and 700kt/a ethylene production capacity. The company has a primary crude processing capacity of 10.5 million tons per annum with a compatible secondary processing capacity, all powered by the leading refining/chemical processing techniques in China.Lanzhou Petrochemical has more than 90 production installations for gasoline, kerosene, diesel fuel and lube oil base stock, etc. In addition to key chemical products like ethylene and synthetic ammonia, the company can produce a wide range of 400 specifications (grades) of petrochemical products, including synthetic resin, synthetic rubber, polypropylene, fertilizer, catalytic cracking catalyst, fine chemicals and organic agents, etc.

PetroChina Lanzhou Petrochemical Company is one of the major integrated refining and petrochemical enterprises under China National Petroleum Corporation (CNPC) and PetroChina. Located in Xigu District, Lanzhou, Gansu Province, the company occupies an important strategic position in China's western refining and petrochemical industry. It integrates refining, petrochemical production, engineering, equipment maintenance, scientific research and supporting services, and serves as a major energy and chemical production base in western China. PetroChina Lanzhou Petrochemical Company has a distinctive position in the history of China's petroleum and chemical industries. Its industrial origins can be traced to the large-scale petroleum and chemical projects established during China's First Five-Year Plan.The former Lanzhou Refinery and Lanzhou Chemical Industry Company were two important industrial foundations of the enterprise. Over decades of restructuring and integration, the refining and chemical operations were progressively consolidated, creating the integrated operating structure associated with today's Lanzhou Petrochemical.This historical background is important because the company is not simply a conventional petroleum refinery. Its development has been closely connected with the formation of China's western petrochemical industry and the development of domestic refining and chemical technologies.According to China Petroleum's corporate publications, Lanzhou Petrochemical has been described as an integrated enterprise covering refining, chemicals, equipment manufacturing, engineering construction and maintenance, and it plays an important role in the energy system of western China. Refining is one of the fundamental businesses of PetroChina Lanzhou Petrochemical Company.The company has developed into a large integrated refining base capable of processing crude oil and converting petroleum feedstocks into transportation fuels, refinery intermediates, lubricating-oil components and chemical raw materials.Publicly available industry information describes Lanzhou Petrochemical as having approximately 10.5 million tonnes per year of primary crude-processing capacity, supported by secondary processing facilities. The complex includes numerous production units covering gasoline, kerosene, diesel, lubricant base stocks and other petroleum products. The significance of this capacity goes beyond crude oil processing. An integrated refinery can optimize different petroleum fractions and route them toward higher-value products. This creates an important connection between the company's refining operations and its downstream chemical manufacturing.One of the major strengths of PetroChina Lanzhou Petrochemical Company is its integration of refining and petrochemical production.The company has historically manufactured a broad portfolio of petrochemical products, including:EthylenePolyethylenePolypropyleneSynthetic rubberSynthetic resinsFertilizer productsCatalystsLubricant-related productsOrganic chemical productsSpecialty chemical materialsPublic information indicates that the Lanzhou complex has more than 90 production installations and can manufacture hundreds of specifications and grades of petrochemical products. This broad product structure gives Lanzhou Petrochemical an important position in China's petrochemical value chain. Instead of relying exclusively on fuel products, the company can convert refinery and chemical feedstocks into polymers, synthetic rubber, chemical intermediates and other higher-value materials.Ethylene is particularly important to the company's petrochemical structure.Ethylene serves as a fundamental building block for numerous downstream materials, including polyethylene, ethylene derivatives and other petrochemical intermediates.Lanzhou Petrochemical has been identified as one of PetroChina's major ethylene production bases. Industry information describes the Lanzhou complex as having a 700,000-tonne-per-year ethylene production capacity associated with its large refining and petrochemical base. The development of ethylene production allows the company to connect refinery operations with polymer manufacturing and downstream chemical production.This refinery-to-ethylene-to-polymer structure is one of the defining characteristics of an integrated petrochemical complex.Polyolefins are another important component of Lanzhou Petrochemical's product portfolio.Polyethylene and polypropylene are widely used in:PackagingFilm productionInjection moldingPipesHousehold productsAutomotive componentsElectrical applicationsIndustrial containersConsumer goodsThe company has continued to emphasize new materials and higher-value chemical products. China Petroleum's reporting has highlighted the company's production of polyethylene, polypropylene and other new-material products, while noting that new-material output has remained among the leading levels within PetroChina's refining enterprises. For downstream manufacturers, the importance of a producer such as Lanzhou Petrochemical lies not only in production volume but also in the availability of different grades designed for specific processing requirements.Lanzhou Petrochemical also has a particularly important historical relationship with China's synthetic rubber industry.The company has developed technologies and products associated with synthetic rubber production, including styrene-butadiene rubber and nitrile rubber.China Petroleum's corporate social responsibility materials describe Lanzhou Petrochemical as the birthplace of China's first synthetic rubber and document the company's development of proprietary technologies for styrene-butadiene and nitrile rubber production. Synthetic rubber products are important raw materials for:TiresSealsHosesBeltsAutomotive componentsIndustrial rubber productsOil-resistant rubber productsThe development of domestic synthetic rubber technology has therefore played an important role in reducing dependence on imported materials and supporting downstream manufacturing.Technology is another defining feature of PetroChina Lanzhou Petrochemical Company.The company's technological development has historically involved the introduction, digestion, absorption and further improvement of advanced petrochemical technologies.Its R&D activities cover areas including:Refining technologyPolymerizationSynthetic rubberCatalystsNew polymer materialsProcess optimizationEnergy efficiencyEnvironmental protectionProduct quality improvementThe company's transformation strategy has increasingly focused on moving from traditional fuel-oriented refining toward higher-value chemical materials and specialty products. In recent corporate planning discussions, Lanzhou Petrochemical has emphasized refining, chemical production, new materials, green development and technological innovation. Modern petrochemical production is increasingly influenced by environmental regulations, energy efficiency requirements and carbon-management objectives.Lanzhou Petrochemical has implemented projects involving energy optimization, cleaner energy substitution, heat recovery, boiler upgrades and emission reduction.China Petroleum has reported projects involving cleaner energy replacement, industrial waste-heat utilization, heating optimization and ultra-low-emission boiler upgrades at Lanzhou Petrochemical. For a large integrated refinery, these improvements are significant because energy consumption is closely connected with manufacturing cost, emissions and overall plant efficiency.The geographical position of PetroChina Lanzhou Petrochemical Company is strategically important.Lanzhou is located at a major transportation and economic intersection in western China. The company therefore provides an important industrial base for supplying petroleum products and chemical raw materials to markets across Gansu and other western and northwestern regions.Its role extends beyond local production. The integrated petrochemical complex contributes to regional manufacturing sectors that depend on polymers, synthetic rubber, chemical intermediates and refined petroleum products.The future development of PetroChina Lanzhou Petrochemical Company is increasingly associated with five major themes:Refining optimizationHigher-value chemical productsNew polymer materialsTechnological innovationGreen and low-carbon manufacturingThe company's current strategic direction emphasizes adjustment of its production structure and movement toward higher-value segments of the petrochemical industry. For global chemical buyers, PetroChina Lanzhou Petrochemical Company therefore represents more than a conventional refinery. It is an integrated refining and chemical manufacturing base with extensive capabilities across fuels, olefins, polymers, synthetic rubber, catalysts and other petrochemical materials.

Lanzhou Petrochemical Company is a major integrated refining and petrochemical producer in western China. As part of the PetroChina and CNPC system, the company combines crude-oil refining, petrochemical manufacturing, synthetic materials, engineering services, research and development, and industrial support functions. Its integrated structure enables the company to convert petroleum feedstocks into a broad range of fuels, chemical intermediates, polymers, synthetic rubber and other petrochemical products.Lanzhou Petrochemical Company is located in Lanzhou, Gansu Province, in the Xigu industrial area.The enterprise originated from two major industrial foundations commonly referred to as Lanzhou Refinery and Lanzhou Chemical Industry Company. These facilities were among the major industrial projects established during the First Five-Year Plan period.Following several rounds of organizational restructuring and integration, the refining and chemical businesses were gradually consolidated into the modern Lanzhou Petrochemical organization. This history explains why Lanzhou Petrochemical today possesses capabilities covering both petroleum refining and chemical manufacturing.The key competitive advantage of Lanzhou Petrochemical is integration.In a standalone refinery, crude oil is mainly processed into fuels and refinery products. In an integrated petrochemical complex, however, refinery streams can become feedstocks for chemical units.The production chain can be broadly understood as:Crude Oil → Refining → Naphtha / LPG / Other Feedstocks → Olefins → Polymers / Synthetic Rubber / Chemical ProductsThis integration improves feedstock utilization and enables a broader product portfolio.Public industry information describes Lanzhou Petrochemical as a large refining base with approximately 10.5 million tonnes per year of primary crude-processing capability and substantial downstream processing capacity. The product portfolio of Lanzhou Petrochemical covers multiple segments.The refining system produces products such as:GasolineDieselKeroseneLubricant-related productsRefinery intermediatesThese products support transportation, industrial energy and other downstream applications.Ethylene is one of the most strategically important chemical products.Ethylene can be used as feedstock for polyethylene and other derivatives. The Lanzhou complex has been identified as one of PetroChina's major ethylene production bases. Polyethylene is a major commodity polymer used across packaging, pipes, films, containers and molded products.Different polyethylene grades can provide different combinations of:Melt flow propertiesDensityMechanical strengthImpact resistanceProcessabilityEnvironmental stress-cracking resistanceTherefore, from a procurement perspective, the exact grade is often more important than simply identifying the producer.Polypropylene is another important polyolefin material.It is widely used in:Automotive partsPackagingHousehold productsFibersNonwoven materialsInjection-molded componentsIndustrial applicationsLanzhou Petrochemical has been highlighted by China Petroleum as a producer of polypropylene and other polymer materials. Synthetic rubber represents another important product family.Lanzhou Petrochemical's historical technology development in styrene-butadiene and nitrile rubber has contributed to China's domestic synthetic rubber industry. Nitrile rubber is particularly relevant to applications requiring oil resistance, including seals, hoses, gaskets and industrial rubber products.For international chemical buyers, understanding the product-grade system is critical.A petrochemical manufacturer may produce multiple grades under the same general chemical name.For example, polyethylene and polypropylene grades can differ significantly in:Molecular weight distributionMelt flow rateDensityAdditive systemMechanical propertiesProcessing methodEnd-use applicationTherefore, purchasing decisions should not be based solely on product names.A professional procurement process normally evaluates:Product Grade + Technical Data Sheet + COA + Application + Packaging + Quantity + Incoterms + DestinationThis is especially important when sourcing petrochemical raw materials for large-scale manufacturing.The technical strength of Lanzhou Petrochemical is closely connected with its long operating history.The company has developed technologies in refining, polymerization, synthetic rubber and catalysts, while also conducting continuous optimization of production processes.Its technical development has increasingly shifted toward:High-performance materialsNew polymer productsProcess efficiencyProduct differentiationEnergy conservationEmission reductionThis transition reflects a broader structural change in China's refining sector.Traditional refineries historically relied heavily on fuel production. Modern integrated complexes increasingly seek to maximize the proportion of higher-value chemical products.One of the most important development directions for Lanzhou Petrochemical is new materials.China Petroleum reported that Lanzhou Petrochemical has developed and manufactured hundreds of product categories and that its new-material production has remained among the leading levels within PetroChina's refining companies. The strategic significance of new materials lies in their higher value density and closer connection with advanced manufacturing.Potential downstream sectors include:AutomotiveElectronicsPackagingMedical productsConstructionIndustrial equipmentConsumer goodsLarge-scale petrochemical production requires strict control over:Raw material qualityReaction conditionsTemperature and pressureCatalyst performanceProduct compositionMechanical propertiesContaminationBatch consistencyFor international buyers, consistency between batches is particularly important because changes in polymer characteristics can affect downstream processing.A qualified supplier evaluation should therefore include technical documentation and, where appropriate, batch-specific certificates of analysis.Environmental performance has become an increasingly important part of modern petrochemical manufacturing.Lanzhou Petrochemical has undertaken projects involving cleaner energy, boiler upgrades, heat recovery and energy efficiency. These projects aim to reduce emissions while improving plant economics. For integrated refineries, environmental improvements can have a direct relationship with production efficiency because energy consumption, fuel utilization, steam systems and emissions are interconnected.The strategic position of Lanzhou Petrochemical can be summarized through three dimensions:First, refining scale.It is a major refining base in western China.Second, petrochemical integration.It connects refinery feedstocks with olefins, polymers, synthetic rubber and other chemical products.Third, technology and new materials.Its historical experience in synthetic rubber and current emphasis on new materials provide a foundation for moving toward higher-value chemical manufacturing.The future development of Lanzhou Petrochemical Company is likely to remain closely associated with the transformation of China's refining industry.The major direction is not simply increasing crude-processing volume. Instead, greater emphasis is being placed on:Optimizing refining structuresExpanding high-value chemical productsDeveloping new materialsImproving polymer product competitivenessStrengthening technological innovationIncreasing energy efficiencyPromoting green manufacturingFor companies sourcing petrochemical raw materials, Lanzhou Petrochemical is therefore an important industrial reference point when evaluating China's western refining and chemical supply chain.

The company is closely associated with PetroChina's refining and chemical operations and is one of the important integrated refining and petrochemical bases in western China.For international buyers researching Chinese petrochemical manufacturers, understanding the relationship between CNPC, PetroChina and Lanzhou Petrochemical Company is essential.CNPC, or China National Petroleum Corporation, is one of China's major integrated energy groups.PetroChina is the publicly listed company associated with CNPC and operates a large portion of CNPC's oil and gas, refining, marketing and chemical businesses.Lanzhou Petrochemical is part of this broader corporate system.Therefore, terms such as:CNPC Lanzhou Petrochemical CompanyPetroChina Lanzhou Petrochemical CompanyLanzhou Petrochemical CompanyChina Petroleum Lanzhou Petrochemicalmay appear in different databases, industrial documents and search results while referring to substantially the same Lanzhou-based petrochemical enterprise.PetroChina's own corporate documentation has listed PetroChina Lanzhou Petrochemical Company among companies under PetroChina's direct control. The company's history is closely connected with China's early petroleum industrialization.The predecessor organizations, Lanzhou Refinery and Lanzhou Chemical Industry Company, were established as major industrial projects during the First Five-Year Plan period.The subsequent integration of these organizations created a combined refining and chemical production structure.This history is significant because it gave Lanzhou Petrochemical a diversified technical base covering both petroleum processing and chemical manufacturing.China Petroleum describes the company as a large comprehensive refining enterprise integrating refining, chemicals, engineering construction, maintenance and research and development. Lanzhou Petrochemical is one of the major refining bases serving western China.Public industry information reports approximately 10.5 million tonnes per year of primary crude-processing capacity, with supporting secondary processing facilities. The refining system produces various petroleum products and chemical feedstocks.The integration of crude processing with chemical production is particularly important because refinery streams can be further converted into higher-value chemical materials.Ethylene represents one of the central links between refining and chemical production.The Lanzhou complex has been identified as one of PetroChina's major ethylene production bases, with industry sources describing approximately 700,000 tonnes per year of ethylene production capacity. Ethylene can then enter downstream production chains for:PolyethyleneChemical intermediatesEthylene derivativesSpecialty chemical materialsThis makes ethylene production strategically important to the company's overall integrated structure.Polyethylene and polypropylene are among the most important downstream polymer materials associated with the company's petrochemical portfolio.Polyethylene is used in:Flexible packagingRigid packagingFilmPipesContainersIndustrial componentsThe specific grade determines processing characteristics and final application.Polypropylene is widely used for:Injection moldingAutomotive componentsPackagingFibersNonwoven materialsHousehold productsChina Petroleum has reported that Lanzhou Petrochemical produces polyethylene, polypropylene and other polymer products as part of its broader new-material portfolio. Synthetic rubber is one of the areas where Lanzhou Petrochemical has considerable historical importance.The company is associated with the development of China's early synthetic rubber industry and has established technologies for styrene-butadiene rubber and nitrile rubber.According to China Petroleum's corporate materials, the company developed its own integrated technologies for styrene-butadiene rubber and nitrile rubber after introducing and improving existing production technologies. This technological foundation has supported downstream industries such as:Tire manufacturingAutomotive rubberIndustrial hosesSealsGasketsOil-resistant componentsIntegrated petrochemical plants depend heavily on catalysts.Catalysts influence:Conversion efficiencyProduct selectivityEnergy consumptionProduct qualityProcess economicsLanzhou Petrochemical has historically been involved in catalyst-related production and technology development.Catalyst technology is particularly important in an integrated refinery because catalytic cracking, reforming, hydrotreating and other processes rely on specialized catalyst systems.Lanzhou Petrochemical's technological development is not limited to production capacity.Its long industrial history has created a technical ecosystem covering:Refining engineeringPolymerizationSynthetic rubberCatalystsNew materialsProcess optimizationQuality controlEnvironmental technologiesRecent corporate strategy has emphasized moving toward higher-value refining and chemical products while strengthening innovation and new-material development. The traditional refining industry faces structural pressure from energy transition, changing fuel demand and increasing environmental requirements.As a result, integrated companies are increasingly moving toward chemical materials.Lanzhou Petrochemical's development of new materials is part of this broader transformation.China Petroleum reported that the company produces hundreds of categories of products and that its new-material output ranks among the leading levels within PetroChina's refining companies. This direction potentially increases the importance of:High-performance polymersSpecialty polymer gradesFunctional materialsAdvanced synthetic rubberDifferentiated chemical productsModern CNPC refining and chemical facilities must simultaneously address production efficiency and environmental performance.At Lanzhou Petrochemical, projects have included cleaner-energy substitution, heat utilization, boiler transformation and emission reduction.These projects reflect a transition from simply expanding production toward improving the efficiency and environmental performance of existing assets. For international chemical buyers, the name CNPC Lanzhou Petrochemical Company can appear during supplier research, manufacturer verification and product sourcing.However, buyers should distinguish between:Corporate Group → Operating Company → Production Base → Product GradeA search for “CNPC” alone is insufficient to determine the actual producer of a specific chemical.A proper supplier assessment should verify:Exact legal/company nameProduction locationProduct gradeTechnical Data SheetCOASDS/MSDSPackagingProduction capacityExport capabilityApplicable certifications and compliance documentationThis is particularly important for polymers and synthetic rubber, where different grades may have substantially different processing characteristics.CNPC Lanzhou Petrochemical Company's future development is closely linked to the transformation of China's refining and chemical industry.The key areas include:Refining optimizationPetrochemical integrationHigh-value chemical productsNew materialsPolymer developmentTechnology innovationEnergy efficiencyGreen manufacturingThe company's long industrial history, integrated refining and chemical structure, and strategic location make it an important component of China's western petrochemical supply chain.

CNPC PetroChina Lanzhou Refinery is a search term commonly used to describe the Lanzhou refining complex associated with PetroChina and CNPC. In the current industrial structure, the Lanzhou refinery should be understood as part of the broader PetroChina Lanzhou Petrochemical Company integrated refining and petrochemical complex rather than as a completely separate modern company.This distinction is particularly important for researchers, chemical buyers and international procurement teams searching for the origin of petroleum products and petrochemical feedstocks.The Lanzhou refinery has deep historical roots in China's petroleum industry.The original Lanzhou Refinery was one of the major industrial projects established during the First Five-Year Plan period.Together with Lanzhou Chemical Industry Company, it formed the industrial foundation from which today's Lanzhou Petrochemical developed.Following several rounds of restructuring and integration, the former refining and chemical businesses were brought together under an integrated Lanzhou Petrochemical structure. Therefore, when people search for CNPC PetroChina Lanzhou Refinery, they are often researching the refining operations of the broader Lanzhou Petrochemical complex.The historical significance of Lanzhou Refinery goes beyond crude-oil processing.The establishment of the refinery helped create a major petroleum industrial center in western China.Over subsequent decades, the facility evolved from a refinery into an integrated refining and chemical complex.This transformation can be summarized as:Refinery → Integrated Refining → Refining + Olefins → Refining + Petrochemicals + Synthetic MaterialsThis development mirrors the broader evolution of China's petroleum industry.The primary function of the refining system is to process crude oil into usable petroleum fractions and chemical feedstocks.Public industry information places the primary crude-processing capability of Lanzhou Petrochemical at approximately 10.5 million tonnes per year. The refining system can produce products associated with:GasolineDieselKeroseneLubricant base stocksChemical feedstocksOther refinery productsThe exact product slate depends on crude characteristics, refinery configuration, operating conditions and downstream demand.The most important transformation of the Lanzhou refinery is its integration with chemical manufacturing.Modern refining complexes do not simply maximize fuel production.Certain refinery fractions can become feedstocks for petrochemical units.For example:Crude Oil → Naphtha → Ethylene → Polyethyleneand:Refinery Feedstocks → Olefin / Chemical Units → Polypropylene and Other Chemical MaterialsThis integration allows a refinery to capture additional value from petroleum resources.Lanzhou Petrochemical has been identified as a major PetroChina ethylene production base, with approximately 700,000 tonnes per year of ethylene capacity described in industry information. The integrated Lanzhou complex produces much more than fuels.Its product portfolio includes a wide range of chemical and synthetic materials, including:PolyethylenePolypropyleneSynthetic rubberSynthetic resinsFertilizer productsCatalystsOrganic chemicalsLubricant-related productsPublic sources describe a portfolio covering approximately 400 specifications or grades of petrochemical products. This breadth is one of the defining characteristics of the Lanzhou complex.Integration provides several technical and economic advantages.Different petroleum fractions can be directed to different processing units rather than being used solely as fuels.Petrochemical materials such as polymers and synthetic rubber generally have more specialized downstream applications than conventional refinery fuels.Integrated facilities can adjust production structures according to market conditions and feedstock economics.Refining and petrochemical production at the same industrial base reduces the logistical distance between upstream feedstocks and downstream chemical production.One of the unique features of the Lanzhou refining and petrochemical complex is its historical role in synthetic rubber.The company is closely associated with the birth and development of China's synthetic rubber industry.Its technology portfolio has included styrene-butadiene rubber and nitrile rubber.China Petroleum's published materials note that Lanzhou Petrochemical developed its own integrated technologies for these rubber products and that certain nitrile rubber products subsequently entered international markets. This gives the Lanzhou complex significance beyond conventional petroleum refining.Polymer production has become increasingly important to the company's development.Polyethylene and polypropylene provide raw materials for a wide range of manufacturing industries.For example, polyethylene is widely used in:Packaging filmsContainersPipesIndustrial packagingHousehold productsPolypropylene is used in:Automotive partsInjection moldingFibersNonwoven materialsPackagingConsumer productsThe development of these products allows the refining complex to participate directly in downstream manufacturing value chains.The development direction of Lanzhou Petrochemical is increasingly shifting toward higher-value chemical materials.China Petroleum reported that the company has developed a broad range of polyethylene, polypropylene and other new-material products, with new-material production remaining among the leading levels of PetroChina's refining companies. This reflects a fundamental change in the strategic role of the refinery.The modern objective is not simply:“Process more crude oil.”It is increasingly:“Convert petroleum resources into higher-value materials more efficiently.”Large-scale refineries are energy-intensive facilities.Consequently, improving energy efficiency can reduce both production costs and environmental impact.Lanzhou Petrochemical has implemented initiatives involving:Cleaner energy substitutionBoiler modernizationWaste-heat utilizationEnergy conservationEmission reductionProcess optimizationChina Petroleum has specifically reported cleaner-energy replacement and boiler-related transformation projects at the Lanzhou complex. These initiatives are increasingly important as the refining industry moves toward more stringent environmental and carbon-management requirements.The Lanzhou refinery has strategic importance for several reasons.It supports petroleum-product supply in western China.Its refinery streams provide feedstocks for downstream chemical production.Its integrated chemical operations produce important synthetic materials.Its long industrial history has created substantial expertise in refining, polymers and synthetic rubber.Lanzhou Petrochemical is deeply integrated into the local economy. China Petroleum has reported that the company contributes significantly to Lanzhou's economic activity and remains one of the city's major industrial enterprises. For international buyers, the phrase CNPC PetroChina Lanzhou Refinery may appear in searches for:Petroleum productsRefinery feedstocksPetrochemical raw materialsPolyethylenePolypropyleneSynthetic rubberChemical intermediatesLubricant-related productsHowever, procurement teams should verify the actual producer and product grade before making a purchasing decision.A professional sourcing process should confirm:Manufacturer → Production Site → Product → Grade → Specification → COA → SDS → Packaging → Quantity → Trade TermsThis is especially important because the refinery itself is not necessarily the legal manufacturer name printed on a product certificate.The long-term development of the Lanzhou refinery is closely connected with the transformation of China's refining industry.The major trends include:Higher chemical integrationHigher-value polymer productsNew materialsSynthetic rubber developmentRefinery efficiency improvementEnergy conservationCleaner productionTechnological innovationThe result is a gradual transformation from a traditional crude-oil processing facility into a more sophisticated integrated refining and chemical manufacturing complex.
