BP’s 440,000-barrel-per-day (bpd) refinery in Whiting, Indiana, restarted its reformer unit last week, industry monitor IIR Energy said.
BP brought back the 60,000-bpd reformer unit at its facility last Wednesday after shutting it down in late April due to unknown issues.
BP did not immediately respond to Reuters’ requests for comment.
The Whiting refinery, the largest in the U.S. Midwest, produces a wide range of liquid fuels, including gasoline, diesel and jet fuel.
