108607 2007-07-05 | Excel Paralubes Sulfur Recovery Unit Stack | Cause: start up post-Gustav causes flari Followup: No Notes: Abnormally high concentration of light hydrocarbons in the Reaction Furnace. The change in feed composition reduced the unit's effectiveness at converting H2S to sulfur. As a result, the concentration of H2S went beyond the hourly permit limits fromthe SRU sta | 6.0 pounds |
103301 2007-07-05 | South Flare - EQT 080 | Cause: upset in the ARU Followup: No Notes: Level indicator on #2 regenerator tower malfunctioned and there isn't a redundant level indicator. Root Cause analysis estimates release at 19,800 lbs - approx 3,000 lbs more than original repor | 178.0 pounds |
118250 2009-09-28 | GRP unit | Cause: Exchanger leak in the GRP unit. The channel head was leaking due to a reduction in charge rates. Followup: No Notes: No information given. | 10.9 pounds |
111853 2009-01-07 | North Flare | Cause: A net gas compressor shut down due to high vibrations, this resulted in a high volume of material being sent to the north flare. Followup: Yes Notes: No information given | |
111828 2009-01-07 | North Flare | Cause: Net gas compressor in No. 10 reformer was shutdown due to high vibrations. The shut down caused high volumes of gas and liquids to the North Flare. This resulted in a surge of high pressure on the flare header line to the North Flare. Followup: Yes Notes: Immediately after the discharge, Conoco Phillips shut down Old Spanish Trail Roadway, and the North Flare was taken out of service. A Conoco personnel did a FLIR camera monitoring of the flare header line for VOC leakage. No leaks were found. LDEQ personnel were dispatched to the site later in the day after the discharge. They collected a summa canister air sample offsite and downwind of the North Flare. The canister did not detect any readings. Samples of ditch water was collected by Conoco Phillips on the north side of Old Spanish Trail on Sasol property. The water samples of SO2 was detected to be 0.7-4.0ppm, while H2S and VOCs levels were not detectable. During the collection, the inspectors described a pungent, sulfuric odor. CITIZEN COMPLAINT (T111853)- Ms. Debra Ramirez stated concern over the Conoco Phillips discharge. The LDEQ inspector's observations stated that the release was caused by a malfunction of the net gas compressor in the No. 10 reformer, which relieves to the North Flare. In an attempt to mitigate the release, operations began cutting charge rates to the units and diverting vent streams from the North Flare to the South Flare system. | |
128016 2010-12-07 | amine gas feed line to #1 ECC | Cause: Leak on the amine gas feed line pipe at the #1 ECC #1 sulfur recovery unit. LDEQ report states that "leak was originally discovered when an internal H2S monitor picked-up an unknown quantity from inside the refinery." Followup: No Notes: Feed taken out of the line and nitrogen introduced to purge amine gas; #1 SRU unit shut down; line replaced. | 1,050.0 pounds |
126343 2010-09-10 | piping on Pump P-20038 | Cause: Failure of piping network around the HGVO Product Pumb (P-20038) due to high vibration. Refinery states that offsite impact investigation concluded that .6 to 1/2 barrels of HVGO aerosolized and dispersed into the air. Followup: Yes Notes: RQ: The amount of HGVO released exceeded reportable quantities. The diameter of the discharge piping will be increased to recommended engineering standards and a program will be developed to identify and maintain settings on the spring cans. Second follow-up letter was dated 12/22/10. | |
131210 2011-05-11 | flare | Cause: Flare went out. No further information given. Followup: No Notes: No information given regarding amount released. LDEQ and SPOC reports only; no refinery letter. | |
128741 2011-01-16 | T-74 Oily Sewer Sump | Cause: Refinery unauthorized discharge notification report states that the T-74 oily sewer pump level indicator appears to have failed to start the pumps operating. Overflow of crude oil into a railroad ditch occurred. Followup: No Notes: The oil was cleaned up using vacuum trucks, absorbent booms, and pads. The frequency of operator rounds has been increased. Refinery letter states that no off-site impact occurred and that impact to the sides of railroad ditch were "almost nonexistent." | 0.0 pounds |
152968 2013-12-20 | 4/5 SRU | Cause: The thermal oxidizer on the unit lost the flame when the when the combustion air blower shut down. Followup: No Notes: | |
152618 2013-11-28 | #1 and #2 Sulfur Recovery Units | Cause: On November 28, there was a unit upset due to cold weather which caused a loss of the sour water gas flow indication and a release of sulfur dioxide (SO2) and hydrogen sulfide (H2S). Report states that the amount of pollutants released were less than the reportable quantities, and no further action will be taken. Followup: No Notes: | |
152440 2013-11-16 | T-71001 | Cause: On November 16, a fire occurred within the vapor space of the roof on T-71001, the Sour Water Stripper feed tank at Excel Paralubes.
Immediately after the incident, process changes were made to minimize the flow to the tank. The process of removing feed from the tank was completed at 3pm on November 17. Deinventory of the tank contents is nearly complete with an estimated 2 feet of material left in the tank. The process of diluting and removing the remaining material is expected to be completed throughout the next week. Once the tank is completely emptied, a damage assessment will be completed for the tank and any associated equipment. The cause of the incident is under investigation. Followup: No Notes: The fire was extinguished quickly and no offsite impact occurred. Based on engineering calculations, it is estimated that the combustion emissions of sulfur dioxide and volatile organic carbons from the first did not exceed the respective reportable quantities. | 7.5 pounds |
153631 2014-02-03 | T-38 Flare (EQT 240) of Area D | Cause: An unknown quantity of H2S was released from a flare to the atmosphere due to a pilot flame outage. The source was identified as the T-38 Flare (EQT 240) of Area D, Permit 2626-V9. The flare is equipped with an automatic shut-off valve on the flare piping at the time of the flame outage the valve closed as the intended design, and thus only the material in the flare piping was released. Followup: No Notes: The flare pilots were out for approximately 20 minutes. Engineering calculations determined that the amounts of H2S and VOC release during the outage was less than the reportable quantity. There is no mention of what caused the pilot outage. | |
153147 2014-01-06 | North Flare | Cause: Facility initially reported release of unknown quantities of H2S and Liquified Petroleum Gas. Follow-up letter from the company stated that the release was from the North Flare, due to sudden loss of electrical power in Area C Desalters, causing process upset. Followup: No Notes: Facility initially reported release of unknown quantities of H2S and LPG. Letter stated release of SO2 was below the reportable quantity (RQ) and later confirmed via telephone by a Phillips 66 representative that the amount release was 22 lbs. It was noted that there is no RQ for SO2 under CERCLA regulations but rather the RQ for SO2 under EPCRA regulations is 500 lbs for which reporting to the Louisiana State Police is required. There is documentation of what caused the power outage or duration of the emission. |
