NEW YORK - Valero Energy Corp said on Tuesday a hydrocracker is back at the west plant of its 315,000-barrel per day Corpus Christi, Texas, refinery after a planned unit turnaround was finished.

The HCU turnaround at the Corpus Christi West Plant is complete, and the unit has been restarted, Bill Day, a spokesman for Valero, said in an email.

No other updates this morning, he added, referring to the rest of the leading independent refiner's system.

The planned overhaul on the 36,000-bpd hydrocracker began in late February with the maintenance seen completed around March 14, according to a previous notice the company had filed with state environmental regulators.
