TotalEnergies La Porte TX Plant Reports Flaring


   
   HOUSTON, TX (DTN)--TotalEnergies reported on Tuesday (6/16) an emission 
event at its 1.2 million tons Petrochemicals & Refining USA La Porte Plant in 
Texas, following a unit shutdown in Train 9, according to a filing with state 
environmental regulators.

   The event began on Monday June 15 at 1:53 p.m. and concluded at 4:00 a.m. on 
Tuesday  . A shutdown within Train 9 of the Monument 3 Polypropylene Unit led 
to flaring through the South Flare that surpassed permitted limits, the filing 
submitted to the Texas Commission on Environmental Quality.

   Six air contaminants were released: propylene (1,140.37 lbs), carbon 
monoxide (1,012.98 lbs), propane (291.09 lbs), nitrogen oxides (153.95 lbs), 
ethylene (45.93 lbs), and unclassified VOCs (2.33 lbs). Every compound exceeded 
its permitted emission threshold.

   Operations personnel worked to minimize both the quantity and duration of 
flaring, directing all necessary venting to the South Flare.

    Hydrocarbon quantities were tracked via the South Flare Online Monitoring 
System, while NOx and CO figures were calculated using measured heat load and 
TCEQ-approved emission factors. The incident remains open as of the report date.
