Petroleum Coke (Fuel Grade)

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.

World's largest independent petroleum refiner; 15 refineries in the US (mostly Gulf Coast: Port Arthur TX, Texas City TX, Memphis TN), Canada, UK, and Ireland. Produces elemental sulfur as a mandatory Claus Process byproduct at all its refineries. Port Arthur refinery (210,000 bbl/day capacity) is one of the largest single US refiners; McKee refinery explicitly listed as producing sulfur, sulfuric acid, and LPG. USGS: ExxonMobil, Valero, ConocoPhillips, and Marathon were the leading US sulfur producers in 2018. Texas + Louisiana account for 52% of US sulfur production.

US refining, midstream, chemicals, and marketing company (NYSE: PSX, HQ Houston TX); spun off from ConocoPhillips in 2012. Gulf Coast facilities: Sweeny TX (247,000 bpd) and Lake Charles LA (255,000 bpd). Phillips 66 Partners LP (midstream MLP) owns pipelines and terminals feeding crude to its refineries, including the Gray Oak Pipeline (Permian Basin crude to Texas Gulf Coast) and Liberty Pipeline (Rockies crude). The Sweeny refinery includes an 835,000 bpd fractionation hub that also processes NGL from shale formations — same facility handles both crude refining and NGL processing.

Major integrated oil company; operates Whiting IN (435,000 bpd, largest US Midwest refinery); significant fuel-grade petcoke producer from coking units processing heavy Canadian oil sands crude.

Mexican state oil company; emerging petcoke exporter; Olmeca (Dos Bocas) refinery shipped first petcoke cargo Jan/Feb 2024 (2-2.5M t/yr capacity); owns Deer Park TX refinery (from Shell, 2021); planned coker units at Tula and Salina Cruz could add 3-5M t/yr total.

Leading global petcoke trading intermediary and calciner; Rain CII Carbon (US subsidiary) is the largest single recipient of Indian GPC import quotas (462,589t in FY2025-26); operates calciners in US, India, Belgium, and Russia; sources green petcoke from Gulf Coast refineries.

Largest Russian oil company; petcoke producer from Komsomolsk-on-Amur (260,000 t/yr) and Novokuibyshevsk refineries; subject to US/EU OFAC sanctions since 2022; primarily domestic Russian market supply.

Shell plc (London; LSE/NYSE: SHEL; market cap ~$200B) is a major global natural gas producer and the operator of record for the Groningen gas field (Netherlands) — once the largest natural gas field in Europe with reserves of ~2.8 tcm. Shell (through NAM, a 50/50 joint venture with ExxonMobil) has operated Groningen since 1963. Groningen production was progressively phased down after induced seismicity (earthquakes, 3.5+ Richter) in Groningen province caused structural damage to tens of thousands of homes and generated sustained public opposition. The Dutch government ordered accelerated closure; Groningen production ceased entirely in October 2023 — removing the EU's primary domestic gas supply buffer. Shell also operates the Prelude Floating LNG (FLNG) facility off northwest Australia (world's largest FLNG vessel, 3.6 mtpa), and holds significant gas positions in UK North Sea, Permian Basin, and offshore Brunei.

Oil sands upgrader JV (Suncor 58.74%, Imperial Oil 25%, Sinopec 9.03%, CNOOC 7.23%); fluid coking process produces extremely high-sulfur petcoke (~7% S) as unavoidable byproduct; 164 Mt accumulated on-site by end-2024; no commercial export market due to sulfur content and inland location.

Canada's largest integrated energy company; one of the world's largest oil sands operators. Produces 800,000+ MT/year of marketable elemental sulfur as a mandatory byproduct of oil sands bitumen upgrading. Canada's oil sands bitumen contains ~5% sulfur by weight — at 3.7M barrels/day of extraction, Alberta oil sands theoretically contain 8.3M MT sulfur/year (though only ~3M MT/year is captured and marketed). Suncor ships formed sulfur via rail to Port of Vancouver, B.C. for export to China, South Africa, and Australia. Suncor is also Canada's largest fuel retailer (Petro-Canada brand).

One of Canada's largest oil and gas producers; major oil sands operator (Horizon Oil Sands upgrader, Athabasca Oil Sands Project). Produces elemental sulfur as mandatory byproduct of bitumen upgrading. CNRL's Horizon upgrader processes high-sulfur bitumen; sulfur is formed into blocks/prills and stockpiled or shipped. Canada's oil sands produce ~3M MT/year marketable sulfur; CNRL, Suncor, and Cenovus are the primary contributors. CNRL also operator of largest oil sands project (Jackfish thermal in-situ SAGD operations).
