UDPATE: Valero To Restart Unit At Corpus Christi Refinery
(Updated with details about a unit involved.) DOW JONES NEWSWIRES Thur 10/08/09 Valero Energy Corp. (VLO) said it plans to restart its Complex 1 unit at its Corpus Christi, Texas, refinery by Saturday, according to a filing with environmental regulators Thursday.
“Maintenance will be completed as quickly as possible and the unit will return to normal as soon as possible,” it said in the filing to the Texas Commission on Environmental Quality.
The filing specifically mentioned that the steam methane reformer, or SMR, unit was shut down “for required maintenance” after citing a previously reported incidence at a hydrocracker. Early Wednesday morning, a small fire at the Corpus Christi refinery caused a hydrocracking unit in the West Plant section to shut down. SMR units react methane from natural gas feedstocks with steam to produce hydrogen. This hydrogen is then used to used to process heavier oil streams into lighter products such as diesel and jet fuels using high pressures and temperatures.
As a result of the shutdowns, the company said pollutants such as benzene and sulfur dioxide were emitted from six sources. Last week, the company shut a complex at the refinery for three days of maintenance.
The entire Corpus Christi refinery can process 340,000 barrels of crude a day.
