Accident Classified As: Below Reportable Quantity (BRQ)
Unit 222 Sats Gas Plant experienced an upset due to an over-pressure condition on the debutanizer column. As a result, pressure relief valves lifted, sending debutanizer overhead material to the refinery's North Ground Flare. Root cause was a faulty pressure transmitter.
According to their letter from january 23, 2013, "NA; the event does not reach the level of a reportable release."
The Board Operator decreased pressure on the debutanizer column. The faulty transmitter was replaced. Initial reports from January, 2013 stated no permit limits were exceeded concerning released pollutants. Final calculations from April 4, 2013 determined otherwise.
