How to recover the waste steam at the top of the deaerator in dry gas hydrogen production units

How to recover the waste steam at the top of the deaerator in the dry gas hydrogen production plant? It is currently vented, resulting in significant waste. Seeking advice
The steam discharged from the deaerator contains oxygen, and this is precisely the function of the deaerator. Although the amount of steam seems large, its energy consumption is actually low; compared to the losses incurred by the boiler, this level of energy consumption is negligible. If recovery is indeed desired, it is important to note that the steam cannot be sent out through pressure pipes, as this could lead to a decrease in the deaeration effect or even render it ineffective due to pressure differences
Is it possible to install a cyclone separator with a cooling device to reuse the recovered condensed water?
. . We always empty everything completely without recycling; in fact, not much is wasted
Discharging it directly into the atmosphere – it’s not worthwhile to install additional equipment just to recover that little amount of water and heat
Direct release into the atmosphere means little in terms of recycling value.
