The catalytic cracking reaction has been started; how can the air from the top cooler of the fractionation tower be expelled into the crude gasoline tank? Is there a dedicated steam line?

Experts among the sea friends, could you share information about your devices?
After reversing the blind flange in the reaction vessel, a large amount of steam from the settler enters the distillation tower to be sent directly to the flare to displace air.
Before switching the steam seal, air is driven out of the fractionation tower’s steam; after air cooling and water condensation, it turns into water and enters the separation tank! There should be steam to drive out air from the oil and gas in the separation tank to the compressor inlet! After switching the steam seal, the steam coming from the reactor follows the process before the switch!
When removing the large blind flange, wasn’t all the oil in the bulk oil tank already collected?
By the time the steam seal was switched, the coarse gas oil tank had already been emptied of oil! ! !
There are no steam lines on site, so I’m asking for advice from fellow users! ! !
The crude oil tank is for three-phase separation, so there is no impact.
Storing the oil properly has no impact on the steam.
