Exxon Mobil Corp. (XOM) reported an unscheduled shutdown over the weekend of a pipe still, or distillation unit, at its Baytown, Texas, refinery, but said the impact to production was minimal.

Exxon said the shutdown led to above-normal emissions that began Saturday and ended Sunday.
"There is minimal impact to production," it said. "We expect to meet our contractual commitments."
The 561,000-barrel-a-day Baytown refinery, located 25 miles east of Houston, is the nation's second-largest refinery after Saudi Aramco's 600,000-barrel-a-day Motiva Port Arthur refinery.
