CITGO Reports Unplanned Flaring at Corpus Christi Refinery


   
   HOUSTON, TX (DTN) -- CITGO reported an emissions event at the coker wet 
compressor of its 167,000 bpd Corpus Christi Refinery West Plant, triggering an 
unplanned flaring, according to a filing with the Texas Commission on 
Environmental Quality

   The incident began at 8:40 a.m. on Tuesday (7/21), and lasted one hour and 
45 minutes, ending at 10:25 a.m.

   According to the initial report, flaring became necessary when the West 
Plant coker wet compressor tripped. The flaring occurred at the facility's 
process/emergency flare unit.

   The event released an estimated 101 pounds of hydrogen sulfide and 501 
pounds of sulfur dioxide into the atmosphere. Both compounds are listed with an 
emission limit of zero pounds, meaning the release constituted an exceedance.

   In response, the unit was placed on circulation while operators took 
corrective actions to minimize flaring emissions.

   This is the second unplanned emission reported at CITGO's Corpus Christi 
refinery within one week.
