This caused the pressure relief valve 7991-PSV-18 to lift for 5 minutes. Followup: Yes Notes: Assured they would operate this at a Òlow pressureÓ pending findings of the investigation. | 91.0 pounds |
92941 2006-12-31 | Saturated Gas Plant 7991-V-2 | Cause: Failure of the Process Safety Valve Followup: No Notes: Could not have been predicted, preventative safety measures were in place already. | 3,902.0 pounds |
No LDEQ Reported 2006-04-19 | 293-PSV-4A | Cause: The 293-KN-1 compressor tripped due to a false high level alarm from the suction drum 293-V-5. The suction drum had had been drained by the unit operator but the local level alarm continued to show a high level signal to the compressor. Thie high level alarm indicator caused the compressor to trip unexpectedly. The compressor's turbine could not be reset immediately resulting in 293-PSV-4A lifting to the atmosphere for a short duration. Followup: yes Notes: None | 340.0 pounds |
No LDEQ Reported 2008-03-29 | Pressure Safety Valve (PSV)-850 on sphere 100-T-500 | Cause: Cracked pipe leading to Pressure Safety valve Followup: No Notes: Cracked pipe replaced. Exceeded hourly permit for VOC emissions. Air monitoring performed by refinery personnel near leak and the nearest fenceline. No impact found by refinery personel. Emissions below reportable quanitity. | 205.0 pounds |
136882 2012-02-01 | 1391-FF (1391-PSV-009) | Cause: There was an unexpected increase in the Depantanizer tower's overhead pressure causing PSV-009 to relieve. This was the result of the shutdown of the reboiler due to high burner pressure. Followup: No Notes: The reboiler (1391-H-4) temperature was lowered which lowered the pressure in the Depantanizer Tower allowing 1391-PSV-009 to reseat. There is no LDEQ report and no SPOC report attached to this file. 19,570 pounds released | 2,395.8 pounds |
