ExxonMobil Reports Flaring at Beaumont, TX Refinery

HOUSTON, TX. (DTN) — ExxonMobil reported a one-hour emission event at its 630,000 bpd Beaumont, Texas, refinery due to a valve malfunction that resulted in flaring, according to a filed with Texas Commission on Environmental Quality.

The incident lasted from 3:57 a.m. to 5:15 a.m. on Sunday (12/28).

The chemical hydrocarbon dewpoint (CHD) 2 unit released 11 air contaminants, with sulfur dioxide being the most significant at 1,365.56 pounds. Other emissions included 28.12 pounds of nitrogen, 22.67 pounds of carbon monoxide, 14.83 pounds of hydrogen sulfide, and smaller amounts of various nitrogen compounds and hydrocarbons, the filing showed.

ExxonMobil stated that the process stream was routed to the flare system to minimize emissions while instrument technicians worked to repair the valve.

“No offsite impacts were reported. We expect to meet all contractual commitments,” ExxonMobil stated.
