A brief outage occurred at the aromatics unit at ConocoPhillips' (COP) Sweeny 229,000 bpd oil refinery in Texas The unit went off line for several hours on Friday, when an oil switch on a main transformer failed at about midday, resulting in the loss of power to the unit. Emissions from flaring necessitated reporting to the Texas Commission on Environmental Quality (TCEQ). Power was restored and the unit brought back on line three hours later.
