I have noticed that several distillation columns that have water injection systems at the top for washing, operate at temperatures of 120-125 °C (248-257 °F) and pressures that can be 0.5-1 kg/cm2g (7-14 psig).
I have never seen distillation columns that have water injection systems at the top for washing.
Or do you mean water injection into the overhead line upstream the condenser?
What kind of distillation columns are you talking about? What service?

Injected water that vaporizes lowers the temperature of the overhead vapor.
You have to inject so much water that there will be free water left at the inlet of the condenser.
In your simulation you must use an adiabatic flash for that, not simply fixing the temperature at that of the column top.
