UPDATE 1-Valero says Port Arthur coker rates reduced

(Adds details)

NEW YORK Nov 19 (Reuters) - Valero Energy Corp (VLO.N) said Thursday the 105,000-barrel-per-day coker at its 325,000-barrel-per-day Port Arthur, Texas, refinery is at reduced rates after one module was put back in operation after maintenance.

The remaining two modules of the coker will be back in "the next several days," company spokesman Bill Day said.

All three modules of the coker had been shut to repair cracks in the unit's six coke drums. (Reporting by Rebekah Kebede; Editing by David Gregorio)
