Accident Classified As: Reportable Quantity
A process unit upset caused liquid carryover to the amine treatment unit reducing the H2S scrubbing capacity and a valve was inadvertently left open allowing untreated fuel gas (high H2S) gas to mix with the refinery's fuel gas system.
The release was preventable. No further explanation is given.
The valve was closed and fresh amine was added to restore treatment capacity
