HOUSTON - Royal Dutch Shell Plc <RDSa.L> restarted the coker at its 225,300-barrel-per-day (bpd) Norco, Louisiana, refinery on Friday, said sources familiar with plant operations.
Shell shut the 25,000-bpd coker on Monday to clean out carbon that had built up in the unit's furnaces, the sources said.
