Accident Classified As:
On 10/28/2007, MOUSA conducted an emergency shut down of the #3 SRU after being forces to shut down the Hydrocracker (its source of acid gas) following a malfunction at the office vendor facility which provides hydrogen to MOUSA. There was no malfunction or human error on the part of Murphy. On 10/30/2007, MOUSA stared the #3 SRU back up following the above mentioned shutdown
This incident was not preventable because the shutdown of the hydrocracker and subsequent shutdown of the #3 SRU were the result of a malfunction at our offsite hydrogen vendor. BUT, the report says that yes, MOUSA could have attempted a startup without a bypass of the #3 TGT, but that MOUSA opted to use the safer TGT startup procedure of bypassing the TGT in order to better control Reactor Bed temperatures, which was more protective of personnel and equipment. The more aggressive startup optiif it had resulted in another exothermic reaction, could have damaged equipment and resulted in prolonged bypass of the #3 TGT, resulting in significantly greater sulfur dioxide emissions. Remedial Measures - MOUSA suspects that excess oxygen upset t
