HOUSTON (ICIS)--Flint Hills Resources shut down part of its Port Arthur chemicals facility in Texas as a result of an upset during startup, according to a regulatory filing made available on Wednesday.
The upset caused the cracked gas compressor and other equipment to shut down and material was routed to the light olefins unit (LOU).
"In response to the upset, the LOU process was stabilised and feed was subsequently removed from the furnaces," Flint Hills said in a filing with the Texas Commission on Environmental Quality (TCEQ). "An investigation will be performed to determine the cause of the upset."
Flint Hills said it would begin startup after completing additional maintenance activities.
The company would not say when startup would be complete.
Flint Hills said in a regulatory filing earlier this month it had planned to shut down its Port Arthur cracker to repair heat exchangers.
The Port Arthur facility has 621,000 tonnes/year of ethylene capacity.
