HOUSTON (ICIS)--A leak in a lubrication oil line led to the shutdown on Monday morning of the No. 2 fluid catalytic cracking (FCC) unit at Citgo’s Corpus Christi east plant refinery, according to a filing with the Texas Commission on Environmental Quality (TCEQ).

The line for the unit’s power train developed a leak, and to prevent damage to the power train, Citgo immediately shut down the No. 2 FCC unit, the filing said.

During the emergency shutdown, the unit’s opacity analyzer showed that opacity spiked to 79.8% for two six-minute periods, with the average being 32.9%, the filing stated.

The opacity limit is 20%.

The emissions event began at 05:30 Houston time and ended at 08:06, the filing said.

A call to Citgo on Monday seeking the status of the FCC unit and of the refinery was not immediately returned.

Citgo’s Corpus Christi refinery has a production capacity of 4.2m gal/day of gasoline and also makes a host of other feedstock petrochemicals, according to the company’s website.
