About Joliet

The ExxonMobil Joliet Refinery is located about 40 miles southwest of Chicago in Channahon, Illinois. Residents of the area have access to many local activities, from shopping, dining and museums, to golf courses, parks, trails and auto racing events. Add to these the many opportunities the Chicago metropolitan area, or "Chicagoland," has to offer, the Joliet Refinery makes a desirable work location.

The Joliet Refinery is the second newest refinery in the United States and celebrated its 50th year in 2022. As the center of ExxonMobil's Midwest integrated operations, it include pipelines, lubes production, distribution and fuels marketing. The refinery is one of the most energy efficient in the Unites States and processes nearly 250,000 barrels of crude per day into gasoline, ultra-low sulfur diesel, asphalt and other products.

With a workforce of nearly 1,000, we take great pride in the work we do to ensure safe, reliable operations. Further, we are committed to community and education outreach through many longstanding partnerships. The Joliet Refinery is recognized as one of the leading employers in the region, including, in 2018, "Large Business of the Year" by the Joliet Chamber of Commerce and Industry and the "Top Workplace" by the Joliet Herald-News.
