HOUSTON (ICIS)--Flint Hills Resources reported an incident at its Port Arthur light olefins unit in Texas, the company said in a public filing on Friday.
The incident occured on 8 December, and was caused when forward flow from the cracked gas compressor was lost, resulting in a pressure relief valve releasing material to the flare for destruction, the company said in a filing with the Texas Commission on Environmental Quality (TCEQ).
The company routed material to the flare to minimise emissions until the cracked gas stystem returned to steady operation, according to the filing.
The operational status of the unit was not clear.
Flint Hills Resources has a 621,000 tonne/year capacity ethylene unit at its Port Arthur facility, according to ICIS plants and projects.
