4-84 Hydrocracker Flare (FE-301)
Cause: On September 3, 2013, the first and second stages of Motiva's Hydrocracker Unit (HCU) shut down. The shutdown was caused by an instrumentation failure that controlled the lube/seal oil system for the HCU recycle compressors. On September 6, 2013, the Hydrocracker unit began startup operations.


Notes: Immediately after the unit was shut down and secured, maintenance and engineering immediately investigated and identified the instrumentation failure. The instrumentation and engineering groups are developing an inspection list for the next planned unit shutdown to look for deficiencies in the unit instrument systems. No reportable quantities were exceeded; however the permitted maximum hourly emission rate limit was exceeded for Benzene and Sulfur Dioixide.
