US olefins producer Chevron Phillips Chemical reported flaring at the 850,000 mt/year cracker in its Port Arthur, Texas, facility, the company said in a regulatory filing Thursday.
The unit began flaring Wednesday morning as a result of a process unit upset, according to the filing with the Texas Commission on Environmental Quality.
An emissions event associated with the upset ended the same day after the company followed procedures to return the unit to normal operating conditions, the company said in the filing.
A company spokesman did not immediately return a request for further comment.
In markets, S&P Global Platts last assessed spot ethylene Thursday at 13-13.50 cents/lb FD USG for May deliveries and at 13.50-14 cents/lb FD USG for June deliveries.
