An explosion set off a huge fire at Valero Energy Corp's Texas City refinery, Daily Mail reported Saturday.
No injuries were reported at the refinery which produced 225,000 barrels-per-day.
The blaze, which was burning light hydrocarbons, was contained about an hour and a half after it broke out, Texas City Emergency Management office said.

Sources familiar with plant operations said the explosion happened at about 5 p.m.
Valero spokeswoman Lillian Riojas said the company was cooperating with local, state and federal agencies in responding to the fire, which was being fought by the refinery's firefighting team.
'At this time, Valero has very little information as to the cause of the fire,' Riojas said. 'Our primary concern is for the safety of our workers.'
Firefighting units from Texas City and the neighboring Marathon Petroleum Corp refinery were called to the Valero plant, the sources said.
