Cause of Problem: Process Upset

Flaring from the GO-1 Elevated Flare (EPN 1-90) was a result of an unexpected shutdown of the propylene refrigerant compressor.

Notes/Remedial Actions

GO-1 operations took the necessary steps to minimize flaring and safely return the unit to normal operating conditions and the flaring stopped. Investigation and data gathering confirm that no RQ or maximum permitted limits were exceeded.
