(Reuters) - Lyondell Basell's 280,390
barrel per day (bpd) Houston refinery restarted a coking unit on Saturday
following a power failure, according to a notice the refinery filed with Texas
The coker was out of production for about an hour and a half on Saturday
night following the power outage, according to the notice filed with the Texas
Commission on Environmental Quality. Only the coker was hit by a power failure,
the notice said.
A coking unit increases the amount of refinable material in a barrel of oil
and makes petroleum coke, a coal substitute, from residual crude.
