I. The "Energy Province" Label Obscures What Is Actually Built

When outsiders think about Xinjiang's oil and coal, they tend to stop at the resource layer: how large are the reserves, what rank does it hold in national output, where does the crude oil get piped. This framing casts Xinjiang as a raw-material supplier and misses the processing industrial system it has spent decades building downstream of extraction.

Over the past two decades, the actual trajectory of Xinjiang's petroleum, coal and other fuel processing industry has been: refine more crude locally, convert coal into gas and chemical feedstocks, and extend the processing chain from fuel products toward chemical products. This is not a policy aspiration — it is what several large refineries and chemical bases have already accomplished. Dushanzi Petrochemical has grown from a "100,000-ton ethylene" era to producing more than two million tons of ethylene annually. Karamay Petrochemical has become Asia's largest lubricant manufacturer. Hami's private coal chemical enterprise converts coal into liquefied natural gas and ethylene glycol.

This report does not reduce Xinjiang's petroleum and coal processing industry to a table of numbers. The focus is on why this particular industrial structure took shape, what differentiates each cluster, how upstream and downstream segments connect, and what structural pressures this system now faces.

II. Dushanzi: From a Western Development Flagship Project to an Ethylene Powerhouse

Dushanzi Petrochemical, a subsidiary of China National Petroleum Corporation (CNPC), is the largest and best-known refining and chemical enterprise in Xinjiang. Located in Dushanzi District of Karamay City, it processes crude oil from the Karamay oilfield and anchors the entire northern Xinjiang petrochemical cluster.

A landmark milestone defines Dushanzi's scale: in 2009, the "Ten Million Tons Refining, One Million Tons Ethylene" Phase I project was completed, one of the most significant industrial achievements of the Western Development Strategy. At commissioning, the facility had 10 million tons per year of crude oil processing capacity and over 1.22 million tons per year of ethylene production — establishing Dushanzi as a top-tier integrated refining and chemical enterprise.

The expansion did not stop there. By the end of 2023, Dushanzi Petrochemical's annual ethylene output exceeded 2 million tons for the first time — approximately 1.45 million tons from the Dushanzi main facility and approximately 631,600 tons from Tarim Petrochemical, a controlled subsidiary in Aksu Prefecture. In 2025, full-year ethylene production climbed to over 2.0886 million tons, setting a new historical record.

Dushanzi is now advancing the Tarim 1.2 million ton/year Phase II ethylene project, which is expected to be completed in 2026, bringing total ethylene capacity above 3 million tons and establishing the company as a chemical-scale flagship. Alongside capacity growth, Dushanzi has been shifting product mix from fuels toward chemical products; metallocene polyethylene grades are already being exported to Central Asian markets.

III. Karamay Petrochemical: Lubricants at Asian Scale

If Dushanzi's identity is "ethylene," Karamay Petrochemical's identity is "lubricants."

Karamay Petrochemical Co., Ltd., also under CNPC, draws on Karamay's heavy crude oil, which has naturally high viscosity index and is well-suited for base oil production — a raw-material advantage difficult to replicate from other fields. The company operates three high-pressure lubricant hydrogenation units and produces the widest range of lubricant grades among Chinese refineries.

In September 2022, a newly built 150,000-ton/year white oil hydrogenation unit started operations, raising annual white oil capacity to 200,000 tons and establishing the facility as China's largest producer of premium white oil. From January through October 2023, total lubricant product sales reached 796,000 tons, up 18,400 tons year-on-year, setting a historical record for that period — supporting Karamay Petrochemical's position as Asia's largest lubricant manufacturer.

Karamay's municipal government has identified petroleum and petrochemicals as the core industrial pillar, with the long-term target of expanding Karamay Petrochemical's crude processing capacity from the current approximately 5 million tons toward 10 million tons, making it Xinjiang's second 10-million-ton refinery.

IV. The Northern Xinjiang Petrochemical Belt: A Three-Node Structure

Beyond Dushanzi and Karamay, northern Xinjiang's refining industry has a third node: Urumqi Petrochemical, a Sinopec subsidiary with current crude processing capacity of approximately 6 million tons per year and a planning target of 9 to 10 million tons.

These three major refineries, distributed along the northern slope of the Tianshan Mountains, form the "Dushanzi–Karamay–Urumqi" petrochemical industrial belt — the backbone of Xinjiang's manufacturing economy. Regional industrial policy explicitly calls for building this belt into a petrochemical cluster with international competitiveness: extending downstream into high-end polyolefins, synthetic resins, synthetic rubber, aromatic hydrocarbons, and promoting integration with salt chemicals, chemical fibers, textiles, new energy and new materials.

V. Tahe Refinery and Southern Xinjiang: Connecting One Drop of Oil to One Piece of Cloth

Northern Xinjiang's three-node cluster has a southern counterpart centered on Tahe Refinery Co., Ltd. (Sinopec subsidiary) in Kuqa, Aksu Prefecture.

Tahe Refinery processes Tarim Basin heavy crude oil. Its current processing capacity is approximately 3.5 million tons per year, producing gasoline, diesel, jet fuel, asphalt, petroleum coke, sulfur and xylene. Together with CNPC's Tarim Petrochemical in the same region, it gives national oil companies a refining presence in southern Xinjiang.

In September 2025, a major integrated refinery and chemical project at Tahe broke ground. Total investment is approximately 30 billion yuan. The project will expand total crude capacity to 8.5 million tons per year, add 800,000 tons/year of ethylene and 800,000 tons/year of paraxylene, with full completion targeted by 2029. The project is designed to supply chemical fiber feedstocks for southern Xinjiang's textile and apparel cluster, linking the production chain "from one drop of oil to one piece of cloth." Upon completion, it is expected to add approximately 20.2 billion yuan in annual output value, approximately 3.5 billion yuan in annual tax revenue, and create roughly 10,000 jobs.

VI. Hami and Zhundong Coal Chemicals: Converting Coal into Gas, Olefins and Glycol

Xinjiang's energy processing industry runs on two parallel tracks — one based on crude oil, and one based on coal as feedstock, growing simultaneously in eastern Xinjiang.

Hami is the center of the coal chemical track. Guanghui Energy Co., Ltd. (listed on the Shanghai Stock Exchange, code 600256) has built a coal chemical base at Naomaohú in Hami, drawing on abundant local open-pit coal reserves (Hami's total coal production capacity exceeds 72 million tons per year). The company operates two main production lines: coal-to-methanol and coal-to-LNG. The Hami New Energy facility has coal-to-LNG capacity of approximately 7 billion cubic meters per year. Guanghui Energy's Jimunai facility in northern Xinjiang adds 5 billion cubic meters per year of LNG capacity, bringing combined LNG capacity to approximately 12 billion cubic meters per year.

By 2022, Hami's modern coal chemical industrial cluster had formed a combined scale of 5 million tons per year of coal deep-processing products, 20 million tons per year of coal staged-utilization capacity, and 1.6 million tons per year of coal tar hydrogenation — one of the largest modern coal chemical clusters in northwestern China.

Zhundong (Changji Prefecture) is the other major coal chemical zone. The Zhundong mining area, dominated by open-pit mining, has coal production capacity of approximately 81 million tons per year and total water resources of approximately 2.86 billion cubic meters — resource conditions that support coal-to-olefins and other high-value conversion projects. As of mid-2023, commissioned coal-to-olefins capacity in Xinjiang stood at approximately 680,000 tons/year, coal-to-natural gas at approximately 3.375 billion cubic meters/year, and coal-to-ethylene glycol at approximately 1.05 million tons/year — outputs from facilities spread across both Zhundong and Hami.

VII. Structural Pressures on This Industrial System

The scale of Xinjiang's petroleum and coal processing industry is real, but this system also carries several structural pressures.

Tension between feedstock dependence and downstream depth. Xinjiang produces large volumes of crude locally, but shifting refinery product mix from fuels toward chemicals — raising the chemical output ratio — remains an ongoing and incomplete transition for all major refineries. Dushanzi has been on this path for over a decade; Urumqi Petrochemical and Karamay Petrochemical still have significant room to deepen their chemical chain extensions.

Water availability as a hard constraint on coal chemical expansion. Hami and Zhundong hold enormous coal reserves, but the region's arid climate makes water supply a binding limit on coal chemical capacity growth. Coal conversion processes consume substantially more water per unit of output than coal extraction itself; the available water base will directly determine the ceiling on project scale.

Long-term carbon transition under an emissions cap. Petroleum refining and coal chemicals are both high-carbon industries. As Xinjiang's industrial carbon peaking roadmap advances, all participants face the structural question of how to maintain or expand output while materially reducing carbon emission intensity.

North–south industrial chain integration is still forming. Connecting northern Xinjiang's ethylene output with southern Xinjiang's textile manufacturing — linking Tahe Refinery's integrated chemical capacity with the cotton spinning clusters of southern Xinjiang — is the policy blueprint. Whether this chain can operate at competitive economics across several hundred kilometers of distance and logistics will be demonstrated by actual project data over the next several years.

VIII. Research Institute Assessment

The core value of Xinjiang's petroleum and coal processing industry lies not in the size of its resource reserves but in the fact that a substantial share of those resources is now processed locally, and the processing chain is extending progressively toward chemical products. Dushanzi's ethylene output exceeding two million tons, Karamay's lubricant sales approaching one million tons, Hami's LNG capacity at twelve billion cubic meters — these are not planning targets; they are actual production volumes.

The next stage of this industrial chain depends on whether several things can advance in parallel: whether refineries can materially raise their chemical product output ratios; whether coal chemical projects can find a sustainable growth path within water resource constraints; whether the Tahe integrated project can make the "refining–chemical fiber–textile" chain economically viable. The Institute's assessment is that the scale of this system is already sufficient to merit serious industrial analysis. The real test, however, is not whether Xinjiang can produce — it can — but whether what it produces can be sold at sufficient margins and maintained at scale under carbon constraints. Those answers will become clearer before 2030.
