Motiva Enterprises LLC    last week opened its Port Arthur refinery, the largest in the U.S., with full potential output of 600,000 barrels per day, The Galveston Daily News reports. That dropped the BP refinery, with 475,000 barrels per day, down a spot in the ranks. When Marathon Petroleum Corp. (NYSE: MPC) completes the expansion of its Garyville, La., refinery, the BP refinery will drop down another place, the Daily News reports. The Louisiana refinery currently has full potential output of 464,000 barrels per day, but after the expansion is complete, that could increase to at least 475,000 barrels per day. The other refineries currently at the top of the list include Exxon Mobil Corp    .’s (NYSE: XOM) Baytown refinery, at No. 2 with 560,646 barrels per day, and its Baton Rouge, La., refinery, at No. 3 with 502,000 barrels per day.
