HOUSTON (ICIS)--US-based Chevron Phillips Chemical (CP Chem) has not issued any more information on Wednesday about emissions released at its Sweeny complex in Texas.
On Tuesday, an ethylene unit was forced to shut down after a gas-fired turbine/propylene compressor went out, according to a filing with the Texas Commission on Environmental Quality (TCEQ). The company had then begun to re-start the unit.
“Hydrocarbons under pressure in process vessels were released to the flare header and to relief valves during shutdown and subsequent start-up activities,” CP Chem said in the filing. “Operations personnel brought the equipment down, minimising the duration of the event and the associated emissions.”
