DAVENPORT, FL (DTN) - CITGO Petroleum reported an unplanned shutdown of the
No. 2 fluid catalytic cracking unit (FCCU2) at its 165,000 bpd Corpus Christi
refining complex in Texas following communication issues, according to a filing
submitted Friday (11/6) to the Texas Commission on Environmental Quality (TCEQ).
The incident began Thursday (11/5) at approximately 3:13 p.m. CT and ended
Friday (11/6) at 3:13 p.m., lasting 24 hours at the refinery's East Plant.
The refinery reported estimated emissions of 5,001 pounds of carbon monoxide
from the FCCU2 regenerator and electrostatic precipitator (ESP), along with
opacity reaching 90%, exceeding the permitted limit of 20%.
CITGO said communication issues triggered the unexpected shutdown, prompting
refinery personnel to stabilize processing units and carry out a controlled
startup to minimize emissions.
The FCCU converts heavier petroleum streams into gasoline blendstocks and
other lighter products, making it a key component of the refinery's gasoline
production operations. The filing did not indicate whether the unit had fully
resumed normal operations or quantify any impact on gasoline output.
The latest incident follows an October 21 disruption at the same refinery's
East Plant, when a loss of steam from a third-party supplier forced multiple
processing units to shut down.
DTN reached out to CITGO Petroleum for additional details but did not
receive an immediate response.
