A fire at a sludge tank injured one worker. The blaze erupted while maintenance was being performed on the tank; production was not impacted.
A hydrogen sulfide leak from a pipe was repaired; the leak was said to have affected production. A worker collapsed and died while in the process of repairing the leak on Oct. 6, but it has yet to be determined if the death was related to the leaking gas. Operations were back to normal as of Oct. 14.
The 145K-b/d FCCU is anticipated to reach normal rates by the weekend of Oct. 16-17, after being closed on Oct. 6 by a weather-related power outage, and then later restarted on Oct. 8.
Flaring occurred when a wet gas compressor tripped offline at a heavy oil cracker at the west plant. The unit was quickly returned to service, and production was not affected.
*Sinclair cut feed to the sulfur units and restarted the SCOT unit. The refiner stated in a regulatory filing, "Hydrocarbon carryover to the No. 3 and No. 4 SRUs caused the TTO on No. 3 to shut down, and the SCOT and TTO on No. 4 to shut down."

A glitch occurred at the No. 1 SRU; the upset did not impact production.
Flaring was reported, due to the loss of a compressor. Operations were curbed to reduce the flaring.
An unspecified equipment failure occurred after H2S was released.
An unspecified unit was shut down, due to a jet fuel leak on a pipeline.
The FCCU suffered a glitch. Workers stabilized the unit shortly thereafter.
An SRU was closed, which caused SO2 flaring.
Maintenance on unspecified units was scheduled.
The refiner warned of planned flaring.
The refiner warned of planned flaring.
A boiler was replaced at the refinery over the weekend of Oct. 16-17 as part of routine maintenance.
The last of the plant's three 180K-b/d CDUs was restarted after an oil leak sparked a fire at a residual desulfurization unit.
The unit will be closed for more than 40 days of planned work.
One of the two 21.5K-b/d FCCUs will be closed for scheduled work.
The refinery suffered a power failure and saw complications during a restart attempt.
Shell said on Oct. 15 that it has postponed maintenance on a hydrocracker to spring 2011; the work had been scheduled to take place in 4Q 2010.
Units at the plant that were shut in Sept. will be restarted by the end of Oct., to boost fuel output in response to strikes over pension reforms in France, which have crippled the country's refining industry.
The No. 1 CDU, which was damaged in a pipe explosion, commenced a restart on Feb. 17. After the CDU reaches planned rates, the refiner will restart, one by one, the VDU, the SRU, and the reformer. The distillate dewaxing unit, where the explosion occurred, is expected to be restarted following the recent conclusion of an investigation into the incident, Silver Eagle said on Sept. 27.
The plant will be shut for 45 days of annual maintenance. Stocks are said to be adequate to cover requirements.
The refiner plans to carry out a major, 45-day turnaround in March and April 2011. The work is performed once every four years.
The unit was hit by a fire; the fire was quickly extinguished, and no other units were impacted.
Emissions occurred due to a heavy thunderstorm.
A diesel hydrotreater unit was shut, due to an upset that resulted in the release of a diesel mist into the atmosphere.
A compressor malfunction occurred in Complex 7 of the refinery, causing flaring.
A wet gas compressor tripped in the delayed coker, but it did not impact production.

A small fire was extinguished at the plant; the incident did not impact operations.
Production was not affected by unplanned flaring. The flaring occurred due to surplus pressure on the plant's vapor recovery system.
An overnight power outage was due to a transformer failure in a substation. Operations were returned to normal the next day.
Flaring beyond permitted levels was reported from the FCCU in the east plant.
A crude leak from a pipeline within the refinery was contained. The leak occurred when a piece of equipment struck the line.
A malfunctioning FCCU was returned to operation on the afternoon of Sept. 30. The unit is expected to operate at a reduced rate for around two weeks while repairs are completed, the refiner said.
Brief maintenance was to be carried out at the No. 1 FCCU.
The refiner warned of planned flaring amid maintenance, which has been ongoing since early Sept.
An FCCU was taken offline for around one week of work.
*The rupture of a steam line in the east plant knocked offline a CDU, two diesel HTUs, a Hydrobon unit, a sulfolane unit, and a DIH unit. Excess emissions were also reported.
