(Delayed coking) Why do we need to provide deoxygenated water when water is supplied at a small level?

(Delayed coking) When the water supply is small (deoxygenated water and scum refining are given), why should deoxygenated water be used?
There is no need for this, what we give is recycled cold coke water.
I agree with the second floor, everyone recycles cold coke water. Wouldn't it be a big waste to use deaerated water? High energy consumption?
Supplying deoxygenated water can slow down the coking speed and increase the light oil yield.
Agree with the views of the 2nd and 3rd floor, there is no need to use deaerated water, it will increase the cost too much
Our factory also uses cold coke circulating water, which is low-cost but causes damage to the coke tower.
It is true that deoxygenated water is wasted, perhaps to slow down the cooling coke rate and to deal with more scum.
The conversion factor for deaerated water is 9.2. This is not a loss worth the gain. Please enlighten me as to what the specific deep meaning is.
Generally, circulating water is used, and deoxygenated water consumes a lot of energy, but the higher the water temperature is, the higher the water temperature is. At the same time, the chlorine in the water is small, and the corrosion on the top of the fractionation tower is also small.
