111420

2008-12-15
Point Source(s):
Opelousas Natural Gas header

Pollutant(s):
Flammable Vapor - 2,952 pounds
Cause of Problem: Process Upset

An atmospheric safety valve was lifted on the Opelousas Natural Gas header at the Baton Rouge Refinery. The pressure of this header is maintained via a control valve which lets down high pressure natural gas to a low pressure natural gas header. The control valve that connected the high and low pressure headers failed and remained in an open position, resulting in increased pressures in the low pressure header. As the pressure increased, the controller called for the start of a booster compressor. Neither of the two booster compressors started immediately, resulting in the lifting of the low pressure header safety valve, resulting in the release.
The energy booster compressor was started and pressure control was swapped to a separate control valve. This release exceeded the flammable vapor RQ.

2008-12-15
Point Source(s):
PCLA Furnace F-301
unspecified flare

Pollutant(s):
Sulfur Dioxide - 107 pounds
Sulfur Dioxide - 421 pounds
Cause of Problem: Equipment Failure

The refinery PCLA furnace F-301 developed holes in it which caused a release of 421 pounds of sulfur dioxide/day. On the same day, a flaring incident released 107 pounds of sulfur dioxide. Combined, these two sources released 528 pound of sulfur dioxide which is above RQ. The flaring incident occurred due to the depressurizing of the Alky unit for mechanical work after an unexpected shutdown. The unit was depressured after shutdown. This was an unplanned shutdown, which resulted in more light hydrocarbon loading for the vapor recovery system. The vapor recovery system was subsequently overloaded, resulting in a flaring incident. This incident was caused by a process upset.
Additional cooling tower cells started and rebalanced operations to reduced gas sent to the vapor recovery system. SO2 was leaked at a rate of 421 pounds per day from the furnace failure, but no information given as to the duration of the incident. Combined with the flare SO2 release, this incident surpasses the 500 pound RQ for SO2.

Approximately 1.6 barrels of powerformer feed was discovered in the knoxfield separator, which is a tankfield stormwater collection sump. The exact source of this oil is unknown. When the Refinery experience heavy rainfall on July 24th, it is suspected that the oil was flushed through the soil, into the sewer, and onto the separator that leaked from a line on July 18th.
A 5 gallon leak to soil of a similar material was discovered on July 18th. The July 18th leak was secured and no evidence of additional oil was found in the immediate area. A sample of the oil found in the separator on July 24th was analyzed and the characteristics were similar to that of the material from the July 18th leak. It is suspected that some oil from the previous leak may have migrated through the soil and into the sewer leading to this separator. A vacuum truck picked up the oil in the separator. The separator is monitored for additional oil that may accumulate in the next few weeks after the spill occurred as a result of the rain flushing the oil out of the sewer. The line that was found leaking on July 18th will be permanently repaired.

Cause of Problem: Corrosion

Leak was discovered on the pulldown line for the Product Separator Drum at the Powerformer Unit. Initial findings indicate that the leak was caused by internal corrosion of the weld in a stagnant area of the line.
The line could not be isolated from the drum, so the decision was made to shutdown the unit in order to stop the leak. The line was completely depressured. During the process of shutting down the unit, flaring occurred from the #5, 17, and 19 flared. No reportable quantities were exceeded as a result of the flaring. Regular air monitoring was conducted during this event. The spool piece that leaked was replaced with a straight piece of pipe to eliminate the stagnant area in the line. Reportable quantities for benzene and flammable vapors was exceeded.

The transformer failed due to overheating. The air conditioner in the substation was found to have failed causing the temperature in the building to increase and the transformer to overheat. FLaring also occurred.
The unit was depressurized automatically in accordance with the emergency procedures. Temporary ventilation conditioning was installed in the substation to cool the remaining electrical equipment. Total amount of flammable vapor released was 108,206 pounds. Total amount of VOC's released was 93,904 pounds

Sulfur Dioxide - 1,255 pounds
Cause of Problem: Equipment Failure

The hydrogen sulfide analyzer for the NSPS fuel gas system indicated that the hydrogen sulfide levels in the fuel gas system increased. It was not initially known if the analyzer reading was accurate because there was no alarm indication for the operator of any unit malfunction that could have caused the elevated hydrogen sulfide levels. The source of the high hydrogen sulfide was due to a valve misalignment on the T-301 MEA scrubber at the #2 Light Ends Unit. Sour gas was inadvertently lined up through the scrubber, which had been down for repairs, without introducing MEA into the tower. The unscrubbed gas entered the NSPS fuel gas system and caused 33 furnaces in the NSPS system to exceed their maximum permitted limits for sulfur dioxide.
The high hydrogen sulfide stream was blocked away from the scrubber and the hydrogen sulfide level in the NSPS system dropped below the maximum allowable limit.

Cause of Problem: Human Factors

An apprentice operator at West Complex was transferring lube oil from #9 agitator to a product tank. The pump lost suction, the operator assumed the level of oil in the drum was minimal, and the transfer operation was stopped. Per normal procedure, the drain valve was opened to send the remaining residual material to the slop tank via an enclosed sump system. The unattended open valve was found after the shift change. Meanwhile, the sump pumping system was overwhelmed, the lube oil backed up into the agitator basin and spilled over the concrete and entered the sewer.
The amount of material remaining in the agitator was grossly underestimated and the operator left the valve open while attending to another task. The open valve was immediately blocked to stop the release. A vacuum truck began to pick up the pooled oil from the sewer, concrete, and soil. A project to install a high level alarm on the sump is being considered. This alarm would notify the operator of a high level in the sump such that appropriate actions can be taken to prevent an overfill incident. The employee was counseled to follow appropriate procedures and no leave open valves unattended. The contaminated soil was removed.
