   DAVENPORT, FL (DTN) -- ExxonMobil reported an emissions event at its 588,000 
bpd Baytown refinery, the third largest in the United States, after a loss of 
airflow at the plant's No. 3 Fluidized Catalytic Cracking Unit's carbon 
monoxide boiler, a filing with the Texas Commission on Environmental Quality 
(TCEQ) said.

   The event occurred Tuesday (9/8), between 1:00 a.m. and 3:59 a.m. CT, and 
resulted in elevated emissions from the FCCU3 Wet Gas Scrubber, ExxonMobil 
reported in a TCEQ filing the same day.

   The refinery estimated carbon monoxide emissions at 56,269.77 pounds during 
the event. Smaller quantities of particulate matter, sulfuric acid and other 
compounds were also reported.

   Operators made adjustments to stabilize operations and minimize emissions, 
ExxonMobil reported, saying impact to production was minimal and that it 
expected to meet contractual commitments.

   FCC units are a key part of gasoline production, converting heavier refinery 
streams into gasoline blendstocks and other lighter products.

   The Baytown refinery produces gasoline, diesel, jet fuel and other petroleum 
products.

   DTN reached out to ExxonMobil for additional details but did not get an 
immediate response.
