Enterprise Mont Belvieu Unit Flares Hydrocarbons
HOUSTON, TX (DTN) --Enterprise Products Operating reported an emissions
event at the Splitter III Unit at its1.2 million bpd Enterprise East facility
in Mont Belvieu, Texas, following an overpressure incident, according to a
filing with the Texas Commission on Environmental Quality.
The release occurred after elevated ambient temperatures caused the unit's
overhead tower to overpressure, prompting hydrocarbons to be routed to the West
Flare.
The event began at approximately 2:00 p.m. on Saturday (8/22) and lasted
approximately 10 hours, ending around midnight, according to the initial filing.
During that period, the facility released an estimated 3,770 pounds of
propylene, 320 pounds of carbon monoxide, 210 pounds of nitrogen oxides, and 29
pounds of propane, exceeding permitted hourly limits.
Enterprise, the largest NGL fractionation hub in the U.S., said it followed
"good engineering practices" to ensure the vented hydrocarbons were properly
combusted at the flare.
