Why is the acetylene gas coming out of the neutralization tower still needs to be cooled? What is the purpose of that?

Why does the cooler of the neutralization tower need to be cooled, and what is the purpose? Moreover, water at 7 degrees is used; the outlet temperature of acetylene gas is generally around 10 degrees. The control temperature of the scrubber is understandable, as it serves to prevent the high-temperature decomposition of sodium hypochlorite
In the neutralization tower, after removing the acidic substances from acetylene gas, it must be further cooled in a cooler before being sent to the users
What I understand so far is that it’s something like drying! Condense the moisture in acetylene gas, cool and dehydrate it
The neutralization tower is used to absorb the acid mist consisting of sulfuric acid and phosphoric acid carried along with acetylene gas. The neutralization reaction releases heat; the more heat generated, the worse the reaction performance. Similarly, if the heat released during the reaction is not removed, more water mist will be present in the acetylene gas exiting the neutralization tower, which in turn affects the water removal step prior to subsequent reactions. The requirement for 7°C chilled water is primarily determined by the partial pressure of acetylene gas; generally, a temperature range of 10~15°C is considered optimal.
Cool the acetylene gas to remove the moisture entrained in it.
It should be that lowering the temperature allows the components that can condense in the gas phase to do so. Including water vapor, as well as other gaseous components other than acetylene.
Don’t understand the phrase ‘acetylene gas partial pressure’? ? Is there more water vapor at higher temperatures?
Yes, the higher the acetylene gas level, the more moisture will be entrained; otherwise, there would be no need for freeze-drying.
