Citgo Petroleum Corp. shut down a key component of its Corpus Christi, TX, refinery following an oxygen supply disruption from a vendor because of increased demand from the medical industry.
In a filing with the Texas Commission on Environmental Quality (TCEQ) last Thursday (Sept. 2), Citgo said it shut down the Sulfur Recovery Unit B-Train at the West plant of the South Texas facility. Oxygen is used to increase the ability to recover sulfur in the refining process.
The outage was expected to last through Monday (Sept. 6).
Citgo told the TCEQ that it would “safely and efficiently” adjust to changing sulfur recovery unit operating conditions while minimizing emissions throughout the shutdown.
The company’s Corpus Christi refinery includes the West and East plants spread across more than 550 acres in Nueces County. The facility also includes storage and terminals and eight ship channel docks. It has a crude capacity of 167,000 b/d on average and a gasoline capacity of 4.2 million gallons/day on average.
