Point Source(s):
leaking nipple fitting JC504A Recycle Compressor at the C-Reformer Unit

Pollutant(s):
Hydrogen Sulfide - BRQ
Flammable Gas - 2,882 pounds
Cause of Problem: Piping or Tubing

The flammable gas was released from a leaking nipple fitting on the discharge of the JC504A recycle Compressor at the C-reformer Unit. The failure mechanism has been reported to be metal fatigue caused by vibration. The source of the vibration is the reciprocating compressor directly upstream of the leak.
Good engineering practices was followed in setting the inspection frequency of the piping. The fatigue due to vibration is now being studied. The Unit was immediately shutdown to isolate the leak. The failed nipple was replaced and a gusset was installed at the connection.

Toluene - 51,003 pounds
Xylene - 91,154 pounds
Ethylbenzene - 15,408 pounds
Oil - 2,226,000 gallons
Cause of Problem: Weather

Refinery experienced a heavy rainfall event, greater than 8 inches;of rain in 36 hours. 250 psig steam lines became submerged in water and as a result the steam condensed and caused a drop in pressure, eventually stopping the flow of rich amine throughthe Central Amine unit. This resulted in the loss of acid gas production. The SROs eventually shutdown due to lack of feed. Off gas went to the B-12 flare. Rainfall runoff exceeded the available capacity of the wastewater treatment system storm water tanks and the treatment system. When the capacity of the storm water tanks was exceeded, slop oil and wastewater overflowed from the tanks into the protective dike area surrounding the tanks allowing evaporation of benzene, etc.
The lack of amine treatment of refinery fuel gas caused the hydrogen sulfide content in fuel gas to exceed permit limits Hydrogen Sulfide amounts exceeded not reportedÉTo increase the pressure of the steam system and to reuce hydrogen sulfide generation, emergency steam and hydrogen sulfide shedding steps were initiated. Several units feed rates were reduced to minimum and some were shut down. As soon as acid gas was available steps were taken to restart the SRUs. For each restart operations pnnel followed standard operations procedures for startup and shutdown. When the storm water tanks began to overflow, steps were taken to remove slop oil from the tank dike using vacuum dikes. The feed rte of wastewater from the wastewater tanks to

caused the shut down of the Unicracker Unit and during restart there were emissions
Since the reactor section of the Unicracker Unit was shutdown as the result of this incident, will use same case number in any notifications regarding reportable emissions from the restart of the Unicracker Unit. CITGO is evaluating a project to route the non-condensable gas to a compressor on anoher unit for recovery and treatment. If the project is approved,it will be installed at the Unit's next scheduled turnaround.
