Cause of Problem: Instrument Failure

repairs were being done on an exchanger which caused the events to occur
the MEA from the scrubber was temporarily diverted to the slop system where it would not cause additional upsets. The tail gas from the tail gas clean up unit was diverted to the incinerators to reduce hydrogen sulfide emissions; the procedures for removing the absorber tower from service will be updated to reflect the potential to have hydrocarbon condense in the MEA system; . Air monitoring completed outside facility.

Cause of Problem: Equipment Design

the sour water strippers had a larger than normal oil layer.
the controller diverted the tail gas to the incinerators to reduce personnel exposure and the SWS evaluated levels in the feed spheres to ensure no more hydrocarbon would be sent to the SWS and SRLA; the first page of the report states that the hydrogensulfide level was exceeded from 9AM to 9PM on June 17th, and the sulfur dioxide limit from the F-101 and F-102 incinerators was exceeded- even though the actual report only states the levels of sulfur dioxi

caused by the safety valve malfunction
this report involved 3 events over the course of 3 days; the source of the additional gas to RGCU was determined and the vapor pulldown line was opened to reduce pressure in the sphere. This allowed to safety valve to reseat; 63 pounds of nitrogen oxide was released during the incident on the 15th and 16th, and an additional 18 pounds were released on the 17th- making the total pounds released of nitrogen oxide

Cause of Problem: Human Factors

occurred when the pipestills controller reduced the opening on the induced draft guide vanes to optimize furnace efficiency.
the furnace guide vanes were reopened and the furnace returned to its normal carbon monoxide levels. (no typical report #); this was not preventable because this is a new parameter for the Pipestill controllers; they are learning to control to the new limits and how changes in the furnace affect the carbon monoxide emissions

Cause of Problem: Process Upset

the MEA scrubber on No. 2 Light Ends Unit experienced an operational upset due to a high level in the MEA scrubber to overhead drum; GLA-3x compressor shut down causing the RGCU to become overloaded and a gas leakage which flared
operations attempted to restart GLA-3x and then reduced rates to the FCCU to eliminate flaring; a new alarm was added that is more visible and will alert the controller of increased level in the interstage drum; other items identified by the ongoing investigation will be evaluated and implemented; flaring occurred from 3:20 PM to 4:40 PM on April 30th; the Wet Gas Scrubber exceeded its regulatory limit of 500 PPM of carbon monoxide from 4-6PM; the carbon monoxide concentration increased to 639 PPM fhe hour from 1-2 on May 1st

Point Source(s):
West Gas Scrubber

Pollutant(s):
Carbon Monoxide - 855 pounds
Cause of Problem: Maintenance/Procedures

the permit requirements were changed so they had to implement new changes in order to meet the requirements
Since this regulation is new and controller experience with these situations is limited, learnings from this event will be shared with all controllers. The new Wet Gas Scrubber Permit requires the CO furnaces to operate at lower excess oxygen concentrations for nitrogen dioxide emissions, thus making the unit more susceptible to carbon monoxide excursions. Additionally, more experience is needed to control the new permit and regulatory limit

Cause of Problem: Human Factors

furnace smoked for 3 minutes because the fuel gas rate to the furnace increased. This was due to the controller typing 3200 instead of 2300 kscf.
Other controllers were informed of the consequences and were asked to double check manual inputs prior to execution; fuel gas rates were immediately cut back and the air damper was opened.

This report dealt with a possible unlit flare at the ExxonMobil Baton Rouge Chemical Plant. Subsequent investigation led them to believe the flare flame on No. 7 Flare was never extinguished. Even if the flame had been extinguished, calculations indicate that the amount of emissions from time of discovery until the relight sequence was completed would not have exceeded any reportable quantitie

Cause of Problem: Start Up, Shut Down

30 minute power failure on Bulk Power Station #2. See Notes
Information for both LDEQ Incident Report numbers included on same report. Electrician doing work in the area injured. Investigation underway and findings will be implemented. May put automatic bypasses around filters in case they plug. Emissionswere minimized because some units shutdown; the vent gas from TGCU was sent through the incinerators emitting sulfur dioxide instead of the more harmful hydrogen sulfide. Power failure caused the following refinery units to shut down: No. 10 PipestilSLA-10), West Coker, 200 and 400 Trains on the Sulfer Plant, the Tail Gas Clean-up Unit, No. 2 Powerformer, Heavy Cat Napatha Units, No.1 and No.2 Sour Water Strippers, and some Depronanizers. The following Chemical Plant Units also shut down: Linea

Cause of Problem: Instrument Failure

the controller responsible for the operation of the Refinery Gas Compression Unit (RGCU) began experiencing problems
C-50 was started up to eliminate the flaring and was run on manual. Incident not preventable because normal preventative precautions not used due to concern over clanging noises.

Cause of Problem: Corrosion

Corrosion of the underground pipe.
Material in the line was rerouted and the line was blocked out. The soil is being picked up and will be treated offsite. Leak clamped and pipe replaced. Leak not preventable because there have been no previous leaks along this pipeline. No ground water wells in the vicinity of the release

Cause of Problem: Instrument Failure

Control valves created excessive back pressure on the compressors at PCLA, which resulted in the compressor pressure control valve opening to the flare syste
Corrected controls for the pressure control valves for the first part of the flaring event and closed a block valve for the second part of the flaring event; report stated that the release was preventable, but eplained that the flaring from 10:17am to 1:49pm was not preventable because a level instrument was reading incorrectly, which allowed the gas to the flare system.

Cause of Problem: Instrument Failure

100 Unit went off ratio because air control valve failed closed.
The steam leaving the TGCU exceeded the regulatory maximum 12 hour average of 10 ppm of hydrogen sulfide from 3pm to 11pm. Control Valve positioner was repaired. Air bypass valves are being installed on the 100 Unit turnaround. Release unpreventable because this is the first time it has happened and can only be installed while unit is down.

F-1 furnace at the East Coker

Pollutant(s):
Carbon Monoxide - 155 pounds
Cause of Problem: Instrument Failure

the temperature indicator on P-2B was not reading. Restart of feed pump caused the temperature to missread the feed temperature and automatically reduced the firing in furnace F-1. Coil outlet temperature then fell and the furnace firing automatically increased.
The forward control program has been changed, limiting the potential for error in temperature readings and in turn limits the change feedforward controls can make on furnace firing

see notes
this letter served as written notification to comply because the ammonia emissions from the FCCU exceeded the upper bound of its reported normal emissions; the results from May 2004 were significantly higher than the test completed in previous years
