Accident Classified As:
Vacuum tower jet receiver pressured up causing the liquid level in the seal legs to backup and create a higher discharge pressure on the vacuum ring pumps. The increased pressure at the jet receiver resulted in the drum PSV lifting to the flare. The increased pressure on the discharge of the ring pumps cause al 3 pumps to trip on high amps. The ring pumps were drained and restarted at which time the flaring stopped. Exact cause of incident unknown.
Emissions were minimized by roperations reducing charge to the unit. The overhead receiver was drained, the ring pumps were de-inventoried to start up level, and the ring pumps were restarted to reestablish the vacuum on the vac tower and stop the flaring of gases.
