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.

Sulfur Dioxide - 570 pounds
Cause of Problem: No Information Given

As a result of flaring at flare #17, 139 pounds of sulfur dioxide was released into the atmosphere. The SO2 release, in conjunction with the continuous SO2 release of 431 pounds/day from the PCLA Furnaces (State Police Number 08-07187), resulted in a release exceeding the RQ for SO2. No information given regarding the cause of these releases.
Combined release of SO2 from #17 flare and PCLA furances exceeded RQ. PCLA unit rates were reduced and critical overhead condensors were backwashed, and the PCLA furnaces were repaired during the unit turnaround scheduled for the first quarter of 2009.
