CITGO Corpus Christi Refinery Reports SO Emission


   
   HOUSTON, TX (DTN) -- CITGO reported a sulfur dioxide (SO) emission event 
at its 167,000 bpd Corpus Christi West refinery, according to an initial 
incident report filed with the Texas Commission on Environmental Quality on 
Thursday (7/16).

   The event lasted approximately one hour and 40 minutes, beginning at 
midnight and ending at 1:40 a.m. on July 15, 2026.

   According to the filing, a third-party fuel gas processing facility shut 
down unexpectedly, triggering flaring at the West Plant. The flaring released 
SO through the facility's process/emergency flare, identified as unit 
573-ME1. Preliminary investigation confirmed the SO emissions exceeded the 
reportable quantity threshold.

   CITGO stated that it followed its fuel gas balance procedure in response to 
the incident to minimize emissions and bring the flaring event to an end.

   The incident remains listed as open in the TCEQ reporting system. No 
injuries or additional contaminants were reported in the initial filing.
