I. Why Liaoning Is the Core of Northeast China's Refining Industry

China's northeast has two cities named after petroleum — Daqing and Panjin. It also has Fushun, where coal-tar oil processing pioneered China's industrial refining. Liaoning Province holds both Panjin and Fushun, plus the deep-water port of Dalian. Together, these three cities form the backbone of northeast China's refining geography.

According to data from China National Petroleum Corporation (CNPC) on its Liaoning-based enterprises, the province's refining capacity exceeds 68 million tonnes per year, with ethylene capacity approaching 1.2 million tonnes, constituting a complete refining and petrochemical chain. In Dalian and Panjin alone, three companies — Hengli Petrochemical, Dalian Petrochemical, and West Pacific Petrochemical — account for a combined refining capacity of 50.5 million tonnes per year. This concentration reflects a century of industrial accumulation and deliberate national strategic placement.

II. Three-Pole Structure: Dalian, Fushun, and Panjin

Dalian: Deep-Water Gateway and Thousand-Tonne Refining Base

Dalian is Liaoning's gateway to the global crude oil market. CNPC's Dalian Petrochemical branch operates 48 refining units with an annual crude processing capacity of 20.5 million tonnes. Its origins trace to 1933, when the "Manchuria Petroleum Company Dalian Oil Refinery" was established during the Japanese occupation. After 1983 it was absorbed into China Petrochemical Corporation, and in 1998 into CNPC — a lineage spanning nearly a century.

Adjacent Dalian West Pacific Petrochemical, China's first large-scale Sino-foreign joint-venture refinery, specializes in high-sulphur crude processing, with more than 30 product grades across gasoline, jet fuel, naphtha, LPG, and polypropylene. Dalian's Changxing Island (Xizhong Island) is the newest expansion frontier, anchored by Hengli Petrochemical's refining-chemical integration project. Dalian has set a target of 800 billion yuan in petrochemical industry output value by 2035. Its port infrastructure allows cost-effective import of Middle Eastern and African crude at scale.

Fushun: Cradle of China's Refining Industry

Fushun's refining history is even deeper. In 1928, the Fushun Coal Mine Oil Plant began producing fuel oil from coal tar, marking the start of China's industrial-scale petroleum refining. By the 1960s, Fushun Petrochemical had pivoted to processing Daqing crude; by 1966, its capacity had reached 3.63 million tonnes per year, accounting for 40% of national fuel oil output at the time.

Today, Fushun Petrochemical maintains annual crude processing capacity of 10 million tonnes and operates 77 major production units. Its defining competitive advantage is wax: in 2023, it produced 61.7 million tonnes of paraffin wax — the world's largest single-site wax producer, responsible for approximately one-seventh of global paraffin output. Its paraffin exports represent 35% of China's total. This level of specialization is difficult for other refiners to replicate.

Around Fushun Petrochemical, eight industrial chains have formed — ethylene, propylene, C4, C5, aromatics, plastics, paraffin, and petroleum coke — with more than 100 downstream enterprises generating over 10 billion yuan in cluster output. Fushun has set a target of a 100 billion yuan petrochemical industrial cluster.

Panjin: Liaohe Oil Field and the Asphalt-to-Fine-Chemicals Cluster

Panjin is Liaoning's only city with domestic crude oil production at scale. The Liaohe Oil Field headquarters is based here, maintaining stable output of over 10 million tonnes of oil and gas for 37 consecutive years. In 2022, it produced 9.33 million tonnes of crude oil and 841 million cubic metres of natural gas. The proximity of local crude has shaped Panjin's distinct industrial character.

Panjin is already the largest producer of high-grade road asphalt and full-range lube base oil in China: asphalt capacity of 5.5 million tonnes per year and lube base oil capacity of 1.8 million tonnes per year, both national firsts. Baolai Group's subsidiary Panjin North Asphalt Fuel Co. processes 7 million tonnes of crude per year, producing heavy-grade asphalt, lube base oils, and other core products. North Huajin Chemical Industry Group, the largest industrial enterprise under China North Industries Group Corporation, is headquartered in Panjin and operates in three major segments: petrochemicals, chemical fertilizers, and road asphalt.

The Huajin-Aramco Petrochemical and Raw Materials Engineering Project, under construction in Panjin's Liaobin Coastal Economic Development Zone, is designed for 15 million tonnes per year of refining and 1.65 million tonnes per year of ethylene, with total investment of 83.7 billion yuan — the largest single petrochemical investment in Liaoning's history. The Baolai-LyondellBasell light hydrocarbon utilization project's Phase 1 is already operating, producing 1 million tonnes per year of ethylene, 500,000 tonnes of propylene, and 350,000 tonnes of styrene; Phase 2 is planned with an additional 40 billion yuan investment.

III. Supply Chain Structure: From Crude to Fine Chemicals

Liaoning's refining supply chain draws on imported crude (Dalian Changxing Island is the key unloading hub) and local Liaohe crude. Midstream activities centre on refining and commodity chemicals; downstream extends to synthetic resins, synthetic fibres, synthetic rubber, fine chemicals, and advanced chemical materials.

The province's upstream and midstream are well developed; the gap lies in downstream fine chemicals, where refined products still dominate output and value-added remains modest. The provincial transition strategy — summarised as "less oil, more chemicals; less oil, more specialties" — has been consistently articulated in policy documents. Liaoning's chemical fine-processing rate rose from 42% at the start of the 14th Five-Year Plan to 46% in 2023, already above the national average, with a 2025 target of 50% and fine chemical industry revenue exceeding 200 billion yuan.

Intra-chain coordination is also emerging: Liaohe Petrochemical and Dalian West Pacific have established an asphalt supply interchange; Huajin Group and multiple Panjin park companies have formed "wall-to-wall" feedstock supply relationships, reducing intermediate logistics costs.

IV. Challenges and the Pressure of Transition

The pressures on Liaoning's refining sector largely mirror those facing the national industry, but carry regional specificity.

First, consolidation pressure. Some longer-established plants carry ageing equipment; Fushun Petrochemical encountered serious operational difficulties during the 2010s, requiring CNPC-level internal restructuring and capacity renewal. These transitions for state-owned legacy refiners are capital-intensive and multi-year commitments.

Second, environmental compliance. Liaoning's environmental authorities have pushed green development plans for refining, introducing requirements around green hydrogen, CO₂ utilization, and emissions quota management into regulatory timelines.

Third, structural demand shifts. Accelerating penetration of electric vehicles is dampening the growth trajectory of gasoline and diesel demand. Several refineries have proactively adjusted crude processing configurations toward chemical feedstocks — a constraint that simultaneously creates space for repositioning.

Sales teams supplying upstream materials and industrial inputs to petroleum processing enterprises in Liaoning can use Tianxia Gongchang to filter factory directories and decision-maker contacts by Liaoning region and the fuel processing industry, reducing customer acquisition cycle time.

V. Industrial Depth and the Next Chapter

The Dalian-Fushun-Panjin refining cluster was not the product of a single policy cycle. It emerged from a century of industrial layering: from Fushun's coal-tar oil in 1928, to supplying nearly half of national fuel output in the 1960s, to hosting the northeast's largest refining-chemical integration investment today.

Liaoning refining's next chapter will not be defined by scale — scale is already substantial — but by whether it can accumulate genuine technology depth in fine chemicals and advanced chemical materials. The goal is to become not merely northeast China's "oil storehouse," but a high-value node in the chemical supply chain. That transition requires time, capital, and an honest reckoning with the structural inefficiencies inherited from decades of state-planned industrial organisation.
