   DAVENPORT, FL (DTN) -- Enterprise reported Wednesday (5/13) a 24-hour 
flaring at the propane dehydrogenation (PDH) unit of its 1.2 million bpd Mont 
Belvieu Complex facility in Mont Belvieu, Texas, a filing with the Texas 
Commission on Environmental Quality said.

   The event began at 3:00 a.m. CT on Wednesday and is expected to continue 
through 3:00 a.m. CT Thursday (5/14), the filing said.

   According to the details of the event, a safety monitoring system fault 
triggered the shutdown of the Regen Air Compressor B at the complex's propane 
dehydrogenation (PDH) unit, resulting in a flaring activity.

   Estimated emissions included approximately 1,000 pounds of carbon monoxide, 
500 pounds of nitrogen oxides, 100 pounds each of propane and propylene, and 50 
pounds each of ethylene and sulfur dioxide.

   The company said operations personnel were working to limit flaring while 
investigating the cause and implementing corrective actions.

   The facility is among the largest natural gas liquids fractionation hubs in 
North America.

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