Accident Classified As: Reportable Quantity
The bottoms control valve malfunctioned and could not be closed allowing the loss of all amine liquid in the contractor vessel (410-V-3). The hydrocarbon carryover prompted the amine flash drum's (591-V-38) flare valve to open to the Low Pressure Flare (308F-D-1).
This release was not preventable. It was an unexpected malfunction of the amine contractor's control valve allowing a loss of amine liquid levels in the contractor.
The amine contractor's bottoms control valve was manually closed to re-establish liquid levels.
