|OL-5 Elevated Flare (EPN 6-84) & Ground Flare (7-84|
OL-5 Elevated Flare (EPN 6-84) & Ground Flare (7-84)
|Cause: On November 28, 2013, OL-5 operations experienced a false high flow reading on a flow controller that resulted in high pressure in the diethanolamine stripper overhead. The high pressure caused a backup pressure controller to open the OL-5 Elevated Flare and OL-5 Ground Flare.|
Notes: Upon investigation, it was discovered that the false high flow was the result of the plugging of one of the two transmitter taps. OL-5 operations and maintenance personnel cleared a plug from the transmitter taps of the flow controller, and the flow reading returned to normal operating conditions. The OL-5 Process Unit was safely returned to normal operation conditions, and the flaring stopped. Follow up report states that "additional measures to prevent reoccurrence have not been identified".
