Mexican oil giant Pemex on Thursday said it had restarted a catalytic plant at its Minatitlán refinery in southeast Mexico, after fixing the plant's temperature sensor.
The company did not provide details on when the temperature sensor had initially shut off. It said there had been "no setbacks to fuel production" at the refinery, located in the eastern Gulf coast state of Veracruz.
The Minatitlán refinery, whose capacity went up to 246,000 barrels per day in 2012, was also affected by a fire last month.
