HOUSTON (ICIS)--Chevron Phillips Chemical did not have any further details on Monday about an emissions event at one of its ethylene units at its Sweeny, Texas, facility.
A 9 April process upset at Unit 33 caused heavy material to be sent to the flare, which created emissions of several materials, including butadiene (BD), ethylene, ethane and propylene, the company said in a filing with the Texas Commission on Environmental Quality (TCEQ).
The process upset was corrected and the emissions have stopped, according to the filing.
Chevron has a combined ethylene capacity of 1.878m tonnes/year at the facility.
