Big West Oil LLC, a unit of Flying J Inc., said its North Salt Lake City refinery in Utah is normal after a propane line linked to an alkylation unit ruptured Tuesday.
Process rates on the gasoline octane-boosting unit, reduced after the incident, have been restored, Joel Elstein, the refinery manager, said in a telephone interview.
The Utah plant can process 30,000 barrels of oil a day, U.S. Energy Department data show.
