   DAVENPORT, FL (DTN) -- Enterprise reported Monday (5/19) a 16-hour flaring 
event at the BEF Oleflex unit of its 1.2 million bpd Mont Belvieu Complex in 
Mont Belvieu, a filing with the Texas Commission on Environmental Quality said.

   The event began at 3:30 p.m. CT Monday (5/18) and ended at 7:30 a.m. Tuesday 
(5/19), the filing said.

   According to the filing, the BEF Oleflex Unit experienced an upset related 
to reactor effluent driers that overloaded the system with liquid, requiring 
venting process streams to the North Plant flare to prevent a complete unit 
shutdown.

   Estimated emissions included approximately 5,000 pounds of isobutane, 3,000 
pounds of isobutylene, 1,000 pounds of carbon monoxide, 500 pounds of nitrogen 
oxides, 400 pounds of propane, 100 pounds of butane, and 50 pounds of propylene.

   The company said it utilized engineering procedures and maintained flare 
operations to ensure hydrocarbons were properly combusted. Enterprise added 
that liquid was cleared, and the unit returned to stable operating conditions.

   The Mont Belvieu complex is among the largest natural gas liquids 
fractionation hubs in North America and serves as a major center for NGL 
processing, storage, and distribution.

   Enterprise did not immediately respond to DTN's request for additional 
details.
