Is it necessary to connect a nitrogen line to the underground oil-containing wastewater tanks and the amine solution preparation and recovery tanks?

When is O(∩_∩)O generally used? Thanks
If a gas seal is considered, connect it to the nitrogen line; if a solution is used for rinsing, connect it to the water line
There is a line for desalinated water, but it’s closed with a blind flange; the blind flange valve is opened when amine solution is added to introduce water. There is also a line for low-pressure steam purging, which is similarly closed with a blind flange. For gas sealing, is it necessary to use a self-acting control valve to continuously supply nitrogen? The nitrogen pipeline installed now is also closed using a valve assembly and a blind flange
With a gas seal, the self-acting control valve automatically supplies nitrogen
