Valero Starts Up New Hydrocracker Unit at St. Charles Refinery

SAN ANTONIO, July 11, 2013 - The new hydrocracker unit at the Valero St. Charles Refinery has successfully and safely begun operations and is increasing toward planned rates.  The new hydrocracker unit's throughput is rated at 60,000 barrels per day.  Valero started up a similar hydrocracker at its Port Arthur refinery in December 2012.

The hydrocrackers were designed to capitalize on high crude oil and low natural gas prices, and produce primarily diesel to meet growing demand in both domestic and export markets. Each of the units cost about $1.6 billion to construct.

Valero is pursuing projects to expand throughput capacity to 75,000 barrels per day at each of the new hydrocrackers. With successful permitting, the expansion projects are expected to be complete in 2015.  In addition, Valero is pursuing a 20,000-barrel-per-day expansion of the existing hydrocracker at its Meraux refinery that should be complete by the end of 2014.
