Accident Classified As:
Cause of Problem: Piping or Tubing
piece of instrument air tubing failed causing a bypass control valve around a steam generator to close. Flow through the intermediate cycle gas oil circuit stopped, causing de-ethanizer tower to slump, increasing concentration of light material in the de-butanizer tower feed, increased pressure, causing flaring event
Discharge Preventable - Yes
"To prevent a recurrence, operations will open the block valve around the bypass control valve, which will ensure flow through the ICGO loop."
Notes/Remedial Actions
"unit charge rate and riser temperature were reduced immediately following the loss of heat medium into the de-ethanizer reboiler to minimize the loading to the debutanizer tower. The bypass around 2PDC-142 was opened to re-establish flow to the de-ethanizer reboiler."
