The world's refineries, and Baytown's place

Baytown belongs to a global refining system measured in hundreds of thousands of barrels each day. Its refinery is not locally big; it is globally significant.

A kid on Decker Drive looking at the fence should know what she's looking at. On the list of the largest refineries on earth, the one at the end of her street is on the first page — and her county has three of them. Here's the list, from the companies and the government, and what it means to be from a place that's on it.

The scale of the thing

The United States has about 130 refineries that can run around 18 million barrels of crude a day, per the Energy Information Administration; Texas alone has 34 of them with a combined capacity above six million barrels a day — a third of the country's. The Gulf Coast between Corpus Christi and the Mississippi is the densest refining region in the world, and the stretch of the Houston Ship Channel from Baytown to Texas City is its heart. When the international oil market says "the Gulf Coast," it means here.

The largest on earth

By crude capacity, as the operators and governments state it. Figures are the companies' or the EIA's; where sources disagree, the smaller number is used. 1. Jamnagar, India — Reliance. About 1.24 million barrels a day; the largest single site anywhere. 2. Paraguaná, Venezuela — PDVSA. About 940,000, in name; much of it idle for years. 3. Ruwais, Abu Dhabi — ADNOC. Over 920,000. 4. Ulsan, South Korea — SK Energy. About 840,000. 5. Yeosu, South Korea — GS Caltex. About 800,000. 6. Zhenhai, China — Sinopec. About 800,000 after a recent expansion. 7. Port Arthur, Texas — Motiva. 656,400 barrels a day, per the EIA's January 2026 refinery capacity report; the largest in North America, ninety minutes east of Baytown. Motiva's own marketing figure runs higher; this page uses the EIA number for every U.S. site so the ranking compares like with like. 8. Onsan, South Korea — S-Oil. About 669,000. 9. Lekki, Nigeria — Dangote. About 650,000, the newest on the list. 10. Galveston Bay, Texas City — Marathon. 631,000, per the EIA; forty minutes south. 11. Garyville, Louisiana — Marathon. 617,000, per the EIA. 12. Al-Zour, Kuwait — KNPC. About 615,000. 13. Beaumont, Texas — ExxonMobil. 612,000, per the EIA, after its expansion; an hour east. 14. Jurong Island, Singapore — ExxonMobil. About 592,000. 15. Baytown, Texas — ExxonMobil. 564,500 barrels a day, per the EIA's January 2026 report — a smaller figure than the company's own marketing materials sometimes cite, kept here for the same like-with-like reason as Port Arthur above. This one. 16. Ras Tanura, Saudi Arabia — Aramco. About 550,000; the largest in the Middle East by one state source. 17. Mailiao, Taiwan — Formosa. Around 540,000, by secondary sources. 18. Baton Rouge, Louisiana — ExxonMobil. 523,500, per the EIA. 19. Jubail, Saudi Arabia — SATORP. About 465,000. 20. Abadan, Iran — about 429,000 by its own older figure; the oldest big one, opened in 1912. Whiting, Indiana; Yanbu; Antwerp; Rotterdam's Pernis round out the next tier.

U.S. figures above are the EIA's January 1, 2026 refinery capacity report, not each company's own marketing capacity — the two can differ by tens of thousands of barrels a day at the same site. Non-U.S. figures are each operator's or a national source's own stated capacity, since no single global body audits every country's refineries the same way. Recheck this list yearly; the EIA report updates every January.

Read the list again

Five of the twenty are on the Texas–Louisiana coast, and three of those are within an hour's drive of the Lynchburg ferry. Ninety percent of the country's basic petrochemical capacity is in Texas, mostly around Houston, per the Dallas Fed. A refinery worker in Baytown is not working at a big plant in a small town; she is working at one of the largest industrial sites on the planet, in the most concentrated cluster of them anywhere. The only regions that compare are the Persian Gulf and the Korean coast, and neither has Baytown's other half — the chemical plants that turn the refinery's gases into the world's plastics.

Abadan opened in 1912 and Baytown in 1919; both are still running, which says something about how long a refinery lives when it's looked after.

Here versus there

What's the same everywhere: distillation, cracking, the twelve-hour rotation, the turnaround every few years, the control room. What's different is everything around the fence. In Jamnagar the refinery has its own township; in Ruwais the company built the city; on the Korean coast the plants sit inside industrial estates with their own housing. The Gulf Coast model is older and looser — a company built the town in 1923 and then let it become its own, with a college, a city charter and a ferry — and it's why a Baytown operator lives in a subdivision with a yard instead of a compound. Pay is the other difference: the Federal Reserve puts Houston's energy earnings at more than eighty percent above the metro average, and the medians on the jobs pages are among the highest for a two-year credential anywhere in the world. The trade-off is the one the whole section describes: the hours, the heat, the cycle.

The oldest and the newest

Abadan opened in 1912 and Baytown in 1919; both are still running, which says something about how long a refinery lives when it's looked after. Dangote in Nigeria came online this decade, the first new giant in a generation, and it says something else: that the world still builds these, and the craft that knows how to turn one around is a craft that travels the earth. A Baytown welder with a certification and a passport has work in every place on this list.

If you go

A Baytown craftsman's certifications are a passport of their own. The welding qualifications are to the same American Society of Mechanical Engineers code that pressure vessels are built to on every continent; an API inspector's card is recognized wherever an American company built the plant, which is most of the list above; the crane card is the same one the big contractors ask for in Alberta and the Middle East. What changes abroad is everything around the fence — the visa, the housing compound, the rotation (often weeks on, weeks off, with a flight in between), the tax treatment, and the loneliness, which is the turnaround diaspora's stretched across an ocean. Gulf Coast hands have built and turned around refineries in the Persian Gulf, West Africa and South America for fifty years; the recruiters for those jobs know Deer Park and La Marque by name. It's a real road and a hard one, and the people who've walked it come home saying the same two things: the work is the same everywhere, and nowhere else has the ferry.

The kid on Decker Drive

Give her the list. Tell her the fence at the end of the street is fifteenth on earth and one of three within an hour, that the plastic in her lunchbox and the fuel in the bus came from inside it, that the people who run it are the parents at her school, and that the two-year credential at the college downtown is the ticket to the chair in the control room. Then tell her the honest part — the hours, the heat, the funerals that wrote the rules — because a town that's proud for the right reasons raises kids who can hold both. That's what this list is for. Not a boast. A map with her street on it.

Why it matters that you know

Because pride should be accurate. Baytown doesn't need to be told its refinery is the biggest; it needs to be told, correctly, that it's the fifteenth-largest on earth, in the densest cluster on earth, in a town that built a college around it. That's a truer thing to be proud of than a superlative, and it's the thing the kid on Decker Drive should know.

En español

Las refinerías del mundo y el lugar de Baytown: una niña en Decker Drive que mira la cerca debería saber qué mira — la refinería al final de su calle está en la primera página de la lista de las más grandes de la tierra, y su condado tiene tres. La escala: Estados Unidos tiene unas 130 refinerías con unos 18 millones de barriles diarios, según la EIA; Texas sola tiene 34 con más de seis millones — un tercio del país; la Costa del Golfo es la región refinera más densa del mundo y el tramo del Canal de Houston de Baytown a Texas City es su corazón. Las más grandes, por capacidad de crudo según operadores y gobiernos: Jamnagar, India (1.24 millones); Paraguaná, Venezuela (940,000, en gran parte inactiva); Ruwais, Abu Dabi (más de 920,000); Ulsan, Corea (840,000); Yeosu, Corea (800,000); Zhenhai, China (800,000); Port Arthur, Texas (730,000, la más grande de Norteamérica, a hora y media); Onsan, Corea (669,000); Lekki, Nigeria (650,000, la más nueva); Galveston Bay, Texas City (631,000, a cuarenta minutos); Garyville, Luisiana (617,000); Al-Zour, Kuwait (615,000); Beaumont, Texas (609,000); Jurong, Singapur (592,000); Baytown, Texas (588,000 — esta); Ras Tanura, Arabia Saudita (550,000); Mailiao, Taiwán (540,000); Baton Rouge (522,000); Jubail (465,000); Abadan, Irán (429,000, la más vieja, de 1912). Cinco de las veinte están en la costa de Texas y Luisiana; tres a una hora del ferry de Lynchburg; el noventa por ciento de la capacidad petroquímica básica del país está en Texas, según la Reserva Federal de Dallas. Aquí contra allá: lo mismo en todas partes — destilación, craqueo, la rotación de doce horas, el turnaround, la sala de control; lo distinto es lo que rodea la cerca — en Jamnagar y Ruwais la empresa construyó la ciudad; en la Costa del Golfo la empresa construyó el pueblo en 1923 y luego lo dejó ser suyo, con colegio, carta municipal y ferry; el salario de Houston está más del ochenta por ciento sobre el promedio. La más vieja y la más nueva: Abadan 1912, Baytown 1919, las dos funcionando; Dangote, la primera nueva gigante en una generación. El orgullo debe ser exacto: no la más grande, sino la decimoquinta de la tierra, en el grupo más denso de la tierra, en un pueblo que construyó un colegio alrededor.

Si se va. Las certificaciones de un artesano de Baytown son un pasaporte propio: las de soldadura son al mismo código de la Sociedad Americana de Ingenieros Mecánicos con que se construyen los recipientes a presión en todos los continentes; la tarjeta de inspector API se reconoce donde una empresa americana construyó la planta; la tarjeta de grúa es la misma que piden en Alberta y en el Golfo Pérsico. Lo que cambia afuera es todo lo que rodea la cerca — la visa, el campamento, la rotación de semanas con vuelo en medio, los impuestos y la soledad; los que han ido vuelven diciendo lo mismo: el trabajo es igual en todas partes, y en ningún otro lado está el ferry. La niña de Decker Drive. Dele la lista: la cerca al final de su calle es la decimoquinta de la tierra y una de tres a una hora; el plástico de su lonchera y el combustible de su autobús salieron de adentro; la gente que la opera son los padres de su escuela; la credencial de dos años del colegio del centro es el boleto a la silla de la sala de control; y luego la parte honesta — las horas, el calor, los funerales que escribieron las reglas — porque un pueblo orgulloso por las razones correctas cría niños que pueden sostener las dos cosas. No un alarde: un mapa con su calle.
