HOUSTON (ICIS)--Chevron Phillips Chemical reported flaring from its Sweeny 24 cracker in Texas, citing an instrumentation failure in a public filing made available on Tuesday.

The failure was caused by a malfunctioning pressure indicator controller on a de-ethanizer tower overhead, the company said in the filing with the Texas Commission on Environmental Quality (TCEQ). 

Operations made adjustments to control the pressure and was taking appropriate steps to stabilise the unit, the filing said.

Chevron Phillips does not comment on its operations, according to a company spokesperson.

Ethylene unit 24 has 676,000 tonnes/year of capacity. Chevron Phillips has two other crackers at the site with a combined 1.2m tonnes/year of capacity.

One of the crackers is down for planned maintenance. The 907,000 tonne/year unit is expected to resume operations by the end of the month.
