Hexane (extraction solvent)

Chinese state petrochemical company (SSE/HKEx: 600028 / 0386, HQ Beijing). China's largest refiner and the world's second-largest refiner by capacity. Sinopec produces hexane at multiple refineries including Yanshan (Beijing), Maoming (Guangdong), and Zhenhai (Zhejiang) as part of naphtha fractionation. China is now largely self-sufficient in hexane supply through Sinopec and PetroChina, having reduced import dependence via domestic refinery expansion. Sinopec supplies hexane to China's domestic soybean crushing industry (China is the world's largest soybean crusher, processing ~95 million tonnes/year) — an enormous captive hexane market. Sinopec's hexane capacity is embedded in China's strategic plan for food oil self-sufficiency.

One of the world's largest oil and gas companies; major US and global sulfur producer as a Claus Process refinery byproduct. Key US refining locations: Baytown, Texas (largest US refinery complex); Baton Rouge, Louisiana; Beaumont, Texas. Also major international refiner (Antwerp, Rotterdam). USGS listed as one of leading US recovered sulfur producers. Also holds 25% of Tengizchevroil (TCO) in Kazakhstan, making it indirectly a significant producer of high-sulfur crude and associated sulfur. Acquired Pioneer Natural Resources 2024 (~$60B), largest US oil deal since Exxon-Mobil merger.

Major US petrochemical company (JV between Chevron and Phillips 66); produces ethyl mercaptan at Borger, TX and Tessenderlo, Belgium (Tessenderlo expanded 65% in 2017). Ethyl mercaptan is part of a broader organosulfur chemicals portfolio including methyl mercaptan, DMDS (dimethyl disulfide), and specialty sulfur chemicals. Applications: gas odorization, polymer modifiers, agricultural chemicals, pharmaceuticals, water purification, and lubricant additives. Tessenderlo capacity expansion noted by Hydrocarbon Processing (2017). Also the world's leading polyethylene producer (Cedar Bayou, TX cracker complex).

Shell's chemical operations at Deer Park TX (HQ London, NYSE: SHEL). The Deer Park refinery and chemical complex (Shell Chemical LP) on the Houston Ship Channel produces hexane from refinery naphtha fractions. In 2023 Shell completed the sale of its 50% stake in the Deer Park refinery to PEMEX (Mexico's national oil company, which had held the other 50%), making it a PEMEX-controlled facility. Shell Chemicals at Deer Park continues to process naphtha into petrochemicals including hexane solvents. The site is one of the largest integrated refinery-chemical complexes in the US (340,000 bpd refining capacity + chemical units).

Korean petrochemical company; wholly-owned subsidiary of SK Innovation (KRX: 096770, HQ Seoul). SK Geo Centric (formerly SK Global Chemical) produces n-hexane at the Ulsan Complex in South Korea — one of the largest integrated petrochemical complexes in Asia. Korea is a significant hexane exporter to Northeast Asian markets including Japan and Southeast Asia. SK Geo Centric's hexane comes from naphtha cracker residue and refinery naphtha fractionation at Ulsan. Korea's refining industry (SK, GS Caltex, S-Oil, HyundaiOilbank) produces hexane as a refinery byproduct — Korea exports hexane to Asian oilseed processing markets as South Korea's own crushing sector is limited.

French integrated energy and petrochemical company (NYSE: TTE, HQ Paris). TotalEnergies produces n-hexane at the Gonfreville (Normandy, France) and Antwerp (Belgium) refinery complexes. TotalEnergies' Petrochemicals division supplies European hexane markets for oilseed extraction (French/EU canola oil, sunflower oil crushing) and pharmaceutical solvent use. The Gonfreville refinery (Norman Refining, ~246,000 bpd) is one of France's largest. TotalEnergies' hexane is food-grade certified for EU markets where canola (rapeseed) and sunflower oil crushing uses hexane extraction extensively.
