June 10, 2009

The following table lists unplanned and planned production outages at U.S. refineries as reported by Dow Jones Newswires. The information is compiled from both official and unofficial refining sources and doesn't purport to be a comprehensive list.

Most recently, Delek US Tuesday shut a SCOT unit, a unit used to increase the efficiency of sulfur recovery, at its Tyler, Texas, refinery for about four days of unplanned maintenance.

Valero Energy Tuesday shut a crude, vacuum and coker unit at its Saint Charles refinery in Norco, La., following a minor fire. The outages are expected to be brief, the company said.

Tesoro (TSO) said Monday that a power failure at its Kenai, Alaska refinery on June 4 resulted in the shut down of hydrocracking and isomerization units. Repairs are expected to conclude sometime next week and the refinery will then return to normal operations, the company said.

Citgo shut Monday a Shell Claus off-gas treating, or SCOT, unit at its Corpus Christi, Texas, refinery for abut six days of maintenance. Separately, FCCU No. 1, a key gasoline-making unit at the plant, was restarted Saturday following about four days of unplanned work.

Also on Saturday BP (BP) reported a brief period of flaring at FCCU No. 3 at its Texas City plant when emissions caused a relief valve to open to a safety flare stack. The status of the unit is unclear.

WRB Refining (COP, ECA) on Saturday notified state regulators of its intention to restart a gas oil hydrodesulfurization unit at its Borger, Texas, refinery; it was not clear when the unit was taken off line. However, the exact timing of the restart could be any time between June 6 and June 14 the company said. The actual start date, duration and emissions would be provided in a follow-up report.

And on Friday, a wet gas compressor tripped off-line at Exxon Mobil's (XOM) Beaumont, Texas, refinery causing emissions at a coker unit. The status of the compressor, or of the coker unit, isn't clear. Separately, repairs to fix a crack in a drum at Coker Unit No. 6 concluded last week, and the unit was back at planned rates the company said. The drum was taken out of service on May 21.

Sunoco Inc. (SUN) on June 4 shut the key gasoline-making unit in the Girard Point section of its Philadelphia refinery; the FCC unit is the larger of two at the complex. Repairs are expected to take 30 days.

On Wednesday, Sunoco said the FCCU at its Marcus Hook refinery in Pennsylvania was restarted after shutting down unplanned on May 17 following a fire at the plant's ethylene complex.

Citgo said on June 3 that operations at its Lemont, Illinois refinery were back at planned rates following the unplanned shutdown Monday of an FCCU. The unit was restarted Tuesday and the other units affected by the outage were brought back to normal operations throughout the day.
