Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Process Upset

On November 2, 2013, GO-1 had an unexpected process upset which resulted in flaring at the GO-1 Elevated Flare. The flaring resulted from GO-1 taking a stream into the unit from OP-1 which caused the Acetylene Converter to go off specification. The material was flared at the GO-1 Elevated flare to prevent additional upsets in GO-1. Following the investigation and calculations, Shell Chemical confirmed that no reportable quantities or Maximum Permitted Limits were exceeded.
