Who Makes Xylol? A Guide to the Major Producers

Xylol (xylene) is produced on a massive scale as part of the petrochemical stream known as BTX, short for benzene, toluene, and xylene. It is refined mainly from petroleum through catalytic reforming, with a smaller share from coal tar. This guide names the major companies that produce xylene worldwide and explains where it sits in their business.

Key Facts

• Source: most xylene comes from crude oil refining (catalytic reforming), with a smaller share from coal tar.
• Family: xylene is one of the three BTX aromatics, alongside benzene and toluene.
• Scale: the global xylene market is measured in tens of millions of metric tons per year.
• Where: Asia holds about three-quarters of global para-xylene capacity, with China alone near half.
• Main forms: mixed xylenes (solvent grade) and separated isomers, especially para-xylene for plastics.

How Xylene Is Made

Refineries and petrochemical plants produce xylene inside an aromatics complex. Crude oil is refined, a reformer turns naphtha into aromatic-rich streams, and separation units pull out benzene, toluene, and the xylene isomers. Solvent-grade xylol is sold as “mixed xylenes.” Para-xylene is separated out and oxidized to make the raw material for PET plastic and polyester.

Major Xylene Producers Worldwide

Production is dominated by large integrated oil and petrochemical companies, and capacity is concentrated in Asia. Each entry below links to the company’s official site.

China

• Sinopec: China’s largest refiner and among the world’s biggest para-xylene producers.
• CNPC: China’s largest oil and gas company, with aromatics among its petrochemical output.
• CNOOC: a major Chinese state oil company with refining and petrochemical operations.
• Hengli Petrochemical: a large private Chinese refiner with a major para-xylene complex in Dalian.
• Rongsheng Petrochemical and Zhejiang Petrochemical: operators of one of China’s largest integrated refining and aromatics complexes.

Rest of Asia

• Reliance Industries (India): runs the giant Jamnagar refinery complex and is a major global xylene supplier.
• ONGC (India): India’s largest oil and gas producer, with petrochemical operations.
• Indian Oil (India): India’s largest refiner, producing aromatics including xylene.
• Formosa Petrochemical (Taiwan): a refiner and petrochemical producer at the Mailiao complex.
• GS Caltex (South Korea): operates one of the world’s largest single-site aromatics plants.
• S-Oil (South Korea): a refiner producing benzene, toluene, and xylene.
• Lotte Chemical (South Korea): a petrochemical producer offering benzene, toluene, and mixed xylene.
• SK and Hyundai Chemical (South Korea): energy and chemicals producers with aromatics output.
• Idemitsu Kosan (Japan): a refiner producing benzene, para-xylene, and mixed xylene.
• ENEOS (Japan): Japan’s largest refiner, with aromatics production.
• PTT Global Chemical (Thailand): Thailand’s largest integrated petrochemical company.

Middle East

• Saudi Aramco: the world’s largest oil company, expanding in aromatics.
• SABIC: a global petrochemical major, majority-owned by Saudi Aramco.
• NPC: Iran’s National Petrochemical Company, which oversees the country’s aromatics production.

Americas and Europe

• ExxonMobil (US): an integrated oil and petrochemical major that produces xylene at its aromatics complexes.
• Chevron Phillips Chemical (US): a petrochemical producer owned jointly by Chevron and Phillips 66.
• Valero (US): a large refiner with petrochemical and aromatics output.
• Citgo (US): a US refiner producing petrochemical feedstocks.
• Braskem (Brazil): the largest petrochemical company in the Americas.
• Shell: a global energy and chemicals company with aromatics production.
• TotalEnergies: a global energy major with a large chemicals arm.
• BASF (Germany): the world’s largest chemical company.
• INEOS: one of the world’s largest chemical producers, which bought BP’s aromatics business in 2020.
• LyondellBasell: a global chemical producer and refiner.

Many of these companies operate through joint ventures. Saudi Aramco and INEOS, for example, have partnered on a new aromatics complex in Jubail, Saudi Arabia.

Where Xylene Fits Their Business

For most of these producers, xylene is one product in a broad petrochemical portfolio, not a standalone business. The high-value target is usually para-xylene for the polyester and PET chain. Mixed xylenes, the solvent grade sold to the paint, coating, and cleaning trades, is drawn from the same aromatics stream.

For buyers: If you need bulk xylol, you will normally source it through a distributor rather than directly from a refiner. Large producers sell in tanker and rail quantities, while distributors break it down into drums and smaller volumes for the paint and coating trades.

Did You Know?

Asia dominates this business. Asian producers account for roughly three-quarters of global para-xylene capacity, and China alone makes up close to half. A single large aromatics complex can turn out more than a million tons of para-xylene a year.

Frequently Asked Questions

Who is the largest xylene producer?
No single company dominates the whole market, but Sinopec of China is among the largest by para-xylene capacity, alongside other big integrated producers such as Reliance Industries, Hengli Petrochemical, and GS Caltex.

Where is most xylene made?
At refinery-linked aromatics complexes, with most capacity concentrated in Asia, followed by the United States and the Middle East.

Is solvent xylol made by the same companies?
Yes. Solvent-grade mixed xylenes come from the same aromatics streams these producers run, then reach the trades through distributors.
