Accident Classified As: Below Reportable Quantity (BRQ)
On 3/12/2014 Motiva's Hydrocracking Unit (HCU) flared process gas at the HCU Elevated Flare (FE 301) due to the partial shutdown of the HCU. An unexpected seal leak was discovered on the charge pump on the second stage of the HCU. Due to the location of the leak, the unit had to partially shut down to complete repairs. Flaring continued intermittently to stabilize the remaining operating equipment. On 3/29/14 the Hydrocracker Unit began a startup of the unit. Flaring ceased once the charge pump was repaired and the unit restarted. Emitted 0.32 pounds more of Benzene than permitted for.
The seal failure could not have been anticipated.
Immediately after the unit was safely shut down, the problem was investigated and identified. To prevent the reoccurrence of the incident, a new seal was installed on 3/24/14. The seal oil system was checked prior to start up for deficiencies and none were found.
