FLARE - Main Airblower at the #2 FCC, C3/C4 Splitter/ FCCU Fractionator
Cause: the refinery experienced an automatic safety shutdown of the Main Air Blower at the #2 FCC, resulting in the release of FCC catalyst from the #2 FCC ESP stack (EPN #2-77). As MOUSA attempted to start the unit and achieve balanced operations in the refinery, the C3/C4 Splitter experienced a malfunction, resulting in a large flame with smoke emissions at the North Flare. The events may have been related and are under investigation. (Maybe an air pocket got into the system and caused this -see #102043)

Followup: Yes

Notes: This incident report includes two citizen complaints and a self report from Murphy to the LDEQ. Incident #102043, 102007, 102011, and 102050 are all regarding the same incident as best I can tell. In Murphy's report, they acknowledged that the eventresulted in significant flaring from the FCC main column overhead receiver and the C3/C4 Splitter. Also, MOUSA claims that they received three complaints of visible emissions but no allegations of impact. The LDEQ report states that some particulateter was released to the neighborhood and that at the time of the incident there was a north/northwest wind. NOTE- at the time of this report the incident was under investigation. However, no follow-up report was provided to the Bucket Brigade.
