I. Why Guangxi Refining Deserves Its Own Study

When we talk about China's petroleum and coal processing, attention habitually falls on Shandong's independent refiners, Liaoning's Dalian, Zhejiang's Zhoushan, or the modern coal-chemical hubs of Shaanxi, Inner Mongolia, and Ningxia. Guangxi rarely appears on that list. But shift the view to the Beibu Gulf coast, and an underrated new refining base stands here.

Guangxi's petroleum, coal, and other fuel processing industry has a distinct geographic feature — it runs almost entirely along the coastline. The province produces neither oil nor coal at scale; its feedstock is almost all imported by sea, so the whole industry naturally lays out along deep-water ports such as Qinzhou Port and Beihai's Tieshan Port, rather than near oilfields or coal mines as in the north. This "born facing the sea" pattern is the first key to understanding Guangxi refining.

What is more worth studying is its pace of transformation. Guangxi refining is not content to make only finished oil products; leveraging the New Western Land-Sea Corridor and its location facing ASEAN, it is pushing its business from "refining" toward "refining-chemical integration" and "new chemical materials." This report does not aim to vaguely say "Guangxi is doing petrochemicals," but to explain each block of this coastal refining belt in turn: what Qinzhou makes, what Beihai makes, where coal chemistry and new materials fit in, and what kind of customer opportunity the upstream leaves for suppliers.

II. Qinzhou: Starting from Southwest China's First 10-Million-Ton Refinery

The most distinctive card in Guangxi refining is PetroChina Guangxi Petrochemical in Qinzhou.

This refinery was completed and put into production in 2010, the first 10-million-ton-class refining project in Southwest China, with an annual crude-processing capacity of 10 million tons. Its crude is all imported from overseas, processed via a full-hydrogenation route, yielding mainly diesel and gasoline, aviation kerosene, polypropylene, and sulfur. Its weight shows in a set of cumulative figures: over 11 years of operation it processed more than 100 million tons of crude, produced about 94 million tons of gasoline, kerosene, diesel, and other products, generated roughly RMB 480 billion in gross industrial output, and paid about RMB 90 billion in taxes and fees, topping Qinzhou's industrial taxpayer ranking for many consecutive years. For a province oriented toward the inland southwest, growing a refinery of this scale at a coastal port is itself unusual.

The real focus of Qinzhou refining is the refining-chemical integration upgrade now under way. PetroChina Guangxi Petrochemical's refining-chemical integration transformation-and-upgrade project, with total investment of over RMB 30 billion, centers on a new 1.2-million-ton-per-year ethylene unit and supporting downstream processing. It broke ground at Qinzhou Port on July 29, 2023, and is planned for full completion and start-up in 2025. Once built, it will add 1.2 million tons of polymer-grade ethylene, over 600,000 tons of polymer-grade propylene, plus hydrogenated pyrolysis gasoline, styrene, and other basic chemical feedstocks. The significance of this step is to push Qinzhou from "selling finished oil" toward "selling chemical feedstock and materials" — what the industry calls cutting oil and raising chemicals.

III. Huayi Qinzhou: Wiring Coal and Salt Chemistry into One Base

If PetroChina Guangxi Petrochemical is about refining and ethylene, then the Huayi Qinzhou chemical new-materials integration base is about how coal chemistry, salt chemistry, and new chemical materials interlock into chains within one park.

This base spans four industrial chains — modern coal chemistry, light-hydrocarbon cracking, salt chemistry, and petrochemical downstream — advanced in three phases. Phase one broke ground in November 2017 and was completed and put into production in June 2021; phase two was completed in 2022; phase three centers on methanol-to-olefins, extending toward olefin downstream materials such as EVA, biodegradable materials, polyurethane materials, and engineering plastics. It complements the neighboring PetroChina refinery — one side a petrochemical route starting from imported crude, the other a multi-feedstock chemical route starting from coal, salt, and light hydrocarbons — both running side by side in the same coastal zone at Qinzhou Port, forming a feedstock-and-capacity combination hard to replicate whole elsewhere.

To understand Huayi Qinzhou, one must accept that it runs a multi-feedstock, multi-chain new-materials business: it wins by connecting coal chemistry, salt chemistry, and petrochemical downstream within one base, not by betting on a single product. This structure makes its demand for coal, raw salt, methanol, catalysts, and various chemical equipment both varied and stable.

IV. Beihai's Tieshan Port: Southwest China's Only Sinopec Refining Pole

The other pole of Guangxi refining falls at Beihai's Tieshan Port.

Sinopec Beihai Refining & Chemical sits in the Tieshan Port Coastal Industrial Zone of Beihai City, Sinopec's only refining-chemical integration enterprise in Southwest China, with more than 20 production units including crude preprocessing and catalytic cracking, supported by a commercial crude-reserve base and product-oil pipelines. Its current crude-processing capacity is 6.4 million tons per year, with main products spanning gasoline, diesel, aviation kerosene, naphtha, benzene, liquefied gas, polypropylene, asphalt, sulfur, and petroleum coke. In the first eight months of 2023, Beihai Refining produced about 4.4 million tons of clean finished products and chemical products, paid nearly RMB 10 billion in taxes and fees, and led Sinopec's refining-chemical enterprises in per-ton labor productivity. It too is upgrading toward integration, accelerating a 1.6-million-ton-per-year ethylene refining-chemical integration project.

The structural feature of the Beihai pole is "one enterprise carrying one park" — the petrochemical segment of the Tieshan Port Coastal Industrial Zone is largely laid out as supporting capacity around this Sinopec refinery. Its moat lies in the stacked port advantage of a deep-water harbor, offshore crude reserves, and the status of being Southwest China's only Sinopec refining-chemical enterprise — a combination hard for inland regions to move away as a whole.

V. Beyond the Three Blocks: An ASEAN-Facing Coastal Refining Belt

Put Qinzhou's PetroChina refinery and the Huayi base together with Beihai's Sinopec refinery, and add the chemical and new-energy-material projects gradually laid out in Fangchenggang, Yulin, and elsewhere, and the full picture of Guangxi's petroleum and coal processing becomes clear: a coastal refining belt spread along the Beibu Gulf, with two central-state-owned refineries as twin poles and coal chemistry and new materials as the extension.

The scale of this refining belt is expanding fast. Qinzhou's petrochemical output has surpassed RMB 90 billion, doubling from the end of the "13th Five-Year Plan"; per the province's industrial-development action plan, the whole industry targets RMB 240 billion in output by 2025 and aims for RMB 350 billion by 2027, with above-scale enterprises heading toward 1,000. Underpinning this goal is its location — one end connected to the southwest hinterland, the other facing ASEAN markets — channeling finished oil and chemical materials in both directions via the New Western Land-Sea Corridor.

For upstream suppliers, this pattern — refining, chemicals, and new materials laid out vertically yet dispersed across the two ports of Qinzhou and Beihai — means procurement demand that is both layered and distributed. A supplier fixated only on finished oil or a single chemical feedstock will underestimate Guangxi, because the demand chain here is far more complex than a single refinery.

VI. The Upstream Supply Chain: Procurement Systems Particular to a Coastal Port

Guangxi refining's coastal, multi-feedstock pattern means its upstream procurement demand splits into several systems, each with its own character:

  • Imported crude and offshore storage-transport: both refineries import nearly all crude by sea, so demand for crude shipping, terminal transshipment, commercial reserves, and pipeline transport is highly concentrated at coastal ports — procurement that grows in proportion to refinery capacity
  • Coal, raw salt, methanol, and other diverse chemical feedstocks: the coal- and salt-chemistry chains of the Huayi base are stable buyers of coal, raw salt, methanol, and other basic feedstocks, a demand structure clearly different from a plain refinery
  • Catalysts and chemical aids: from refining's hydrogenation and catalytic cracking to ethylene cracking and methanol-to-olefins, Guangxi refining has a rich range of demand for catalysts, aids, and functional chemicals, with rising requirements for performance and stability
  • Petrochemical and coal-chemical equipment: from refineries' atmospheric-vacuum, catalytic, and hydrogenation units, to ethylene cracking furnaces and polyolefin pelletizing lines, to coal chemistry's gasification and synthesis units, Guangxi refining's equipment procurement spans multiple process categories
  • Packaging, tanks, and pipeline materials: packaging for resin products such as polypropylene and polyethylene, along with large volumes of storage tanks, pipelines, valves, and anti-corrosion materials, is a niche procurement expanding as new-material capacity scales up
  • Port logistics and safety-environmental supporting facilities: coastal refining has continuous demand for terminal handling, hazardous-chemical logistics, wastewater treatment, and safety-environmental facilities — procurement that grows alongside capacity expansion

These kinds of demand correspond respectively to several different factory groups: Qinzhou refining and ethylene, Huayi coal chemistry and new materials, and Beihai refining. An upstream salesperson who views Guangxi through the single lens of "the finished-oil supply chain" easily misses the coal-chemistry, new-materials, and coastal-logistics blocks.

Sales teams supplying these Guangxi refining and coal-chemical manufacturers can filter for factory directories and decision-maker contacts by the two dimensions of region and industry — Guangxi × petroleum, coal and fuel processing — on Tianxia Gongchang, turning door-to-door inquiry across the two ports of Qinzhou and Beihai, and across the refining and coal-chemistry chains, into targeted development.

VII. The Institute's Assessment

Pulling Guangxi refining's blocks together, it presents a classic "late-mover, port-based" industrial profile: it does not win on resource endowment, but stands on the stacking of port, central state-owned enterprises, and location. PetroChina built Southwest China's first 10-million-ton refinery in Qinzhou, Huayi wired coal chemistry and new materials into one base, and Sinopec carries Southwest China's only refining pole in Beihai — the three blocks each have their own feedstock routes and their own upgrade propositions, and they are not strongly correlated, which is precisely where this coastal refining belt's resilience lies.

The variables for this structure going forward are distributed across the transformation of each block. Qinzhou's test is whether, after its 1.2-million-ton ethylene unit starts up, it can truly shift its center of gravity from refining to chemicals; Huayi phase three's focus is whether coal chemistry and new materials can make real the later links such as high-end engineering plastics and biodegradable materials; Beihai's proposition is whether its 1.6-million-ton ethylene integration can extend a refinery's port advantage into a complete chemical chain. The three differ in difficulty and pace, but point in the same direction — turning Guangxi from a refining province into an ASEAN-facing base for chemicals and new materials.

The Institute's assessment is this: the weight of Guangxi's petroleum and coal processing lies not in where its refining scale ranks nationally, but in how a coastal province that produces neither oil nor coal has nonetheless raised, along the Beibu Gulf coastline, two central-state-owned refineries and one multi-feedstock chemical base, and is pushing deeper into new chemical materials on the strength of its ASEAN-facing location. This structure — grown from the port, then extending toward the downstream of the chain — means its customer opportunity lies not only in finished oil, but in coal chemistry, new materials, and coastal logistics, the places out-of-province suppliers most easily overlook. For upstream suppliers, recognizing that Guangxi is not one refinery but a coastal refining belt extending downstream is the precondition for efficiently developing Guangxi's refining-factory customers.
