How does the nitrogen interruption protect the dry gas seal of the turbine? ? ?

If there is a disruption in the nitrogen supply, as well as a break in the air supply for the turbine isolator and the secondary seal, and if the oil pump stops operating, what effects will the return oil from the high-level oil tank have on the dry gas seal? Will lubricating oil get into the isolation chamber? How should this be dealt with?
1. Install a buffer tank. 2. Equip the isolation pipeline with instrument air. 3. Install emergency nitrogen cylinders
There are no devices available at the moment! The equipment will be out of service for a short time! Even the oil return leakage from the high-level tank should be minimal, right? There’s also a serrated seal in between!
With a nitrogen interruption and inadequate sealing if handling is not timely, pressure difference will self-regulate, right?
