| 113891 2009-04-01 | Point Source(s): unspecified flare Pollutant(s):Sulfur Dioxide - 857 pounds | Cause of Problem: Equipment Failure Flaring was caused by an overhead condenser leak at the PCLA complex. The overhead material at the PCLA fractionator is cooled using cooling tower water. A leak developed in these condensers which caused cooling tower water to enter the shell side of the overhead condensers. When the cooling tower water evaporated, salts and foulant were deposited in the process side of the overhead condensers, causing an increase in pressure drop. This increase in pressure drop caused the fractionator pressure to increase, and eventually exceed the set pressure of the pressure relief valves. The pressure relief valves released fractionator overhead into the flare gas recovery system, resulting in flaring. Sulfur Dioxide was released to the atmosphere in exceedance of the reportable quantity. | Unit pressure and unit feed rates were reduced to minimize overhead gas rates and eliminate flaring. Release exceeds RQ. |
