Rain triggers Exxon Baytown unit upsets-filing

HOUSTON, April 26 (Reuters) - Heavy rain Friday evening triggered hydrocracker and flexicoker unit upsets at Exxon Mobil Corp's (XOM.N) 567,000 barrel-per-day (bpd) Baytown, Texas, refinery, according to a notice filed with Texas pollution regulators.

Steam pressure at the refinery fell due to the heavy rain. That drop in steam pressure caused the units to go offline, according to the notice filed with the Texas Commission on Environmental Quality. (Reporting by Erwin Seba, editing by Maureen Bavdek)
