No LDEQ Number Available 2005-02-19 | Point Source(s): FLARE Pollutant(s):Sulfur Dioxide - 734 pounds Nitrogen Oxide - 32 pounds | 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. |
No LDEQ Number Available 2005-02-11 | Point Source(s): None Reported Pollutant(s): | Cause of Problem: Other Flaring incident; no details were given. | Incident involved flaring. |
No LDEQ Number Available 2005-02-06 | Point Source(s): None Reported Pollutant(s): | Cause of Problem: No Information Given No information given | Incident involved a leak at the Chemical Plant (BRCP). |
No LDEQ Number Available 2005-01-31 | Point Source(s): Tail Gas Clean Up Unit Pollutant(s):Hydrogen Sulfide - BRQ | 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. |
No LDEQ Number Available 2005-01-31 | Point Source(s): FLARE Pollutant(s):Sulfur Dioxide - 743 pounds Nitrogen Oxide - 35 pounds | Cause of Problem: Other faulty electrical connection caused the compressor to trip on the No. 2 Reformer (RHLA-2); | Restarted PHLA-2 and RHLA-2 and diverted HHLA's tail gas to lower pressure system. Refinery will investigate improvements to shutdown facilities. |
No LDEQ Number Available 2005-01-24 | Point Source(s): No.3 Fluid Catalytic Cracking Unit Pollutant(s):Sulfur Dioxide - 3,476 pounds | Cause of Problem: Process Upset fresh caustic being blocked away from the WGS when the No.3 fluid catalytic cracking unit, PCLA-3, was shutdown for squa | Fresh caustic was lined up to the system to bring sulfur dioxide emissions down. |
No LDEQ Number Available 2005-01-22 | Point Source(s): None Reported Pollutant(s): | Cause of Problem: Other Pit vent release- no other information given | Information limited to pit vent release at the Sulfur Plant. |
No LDEQ Number Available 2005-01-14 | Point Source(s): 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 |
