Phillips 66 said a furnace problem at its Sweeny Refinery in Old Ocean, Texas, caused
Unit 35, previously identified as an aromatics unit, to shut
down, a filing to Texas state environmental regulators made
available Wednesday said.
Refinery operations personnel routed
the emissions caused by the event to
several of the plant's safety flare stacks intermittently
throughout the day and worked to bring Unit 35 back on
The emissions event lasted just under 12
hours, the filing to the Texas Commission on Environmental Quality said.
Aromatics, which are produced in the catalytic reforming of
naphtha, are used in the production of petrochemicals and can be added to
gasoline to raise its octane rating.
The Sweeny refinery processes up to 247,000
bpd, including large volumes of heavy, sour crude.
