what happened
Exxon Mobil has taken one of its catalytic reformers offline at the 275,000-barrel-per-day Joliet refinery in Illinois, according to Wood Mackenzie. The research firm linked the shutdown, which began on October 20, to lower stack activity and higher flaring. The idled unit has a capacity of 50,000 barrels per day.
An Exxon spokesperson said the company is working to resolve an operational issue and that the safety of the community and workforce remains its main priority. The spokesperson did not provide further operational details. The refinery had already been down for two weeks after a power outage in September.
Joliet is a key fuel supplier for the US Midwest and, according to the company's website, can produce about 11 million gallons of gasoline and diesel per day.
why it matters
The halt comes as the global fuel market is tight, with the Middle East conflict and Ukrainian attacks on Russian refineries squeezing supply. A prolonged cut in output at a major plant could support gasoline and diesel prices in the US Midwest.
