A gas mixture containing water vapor has a dry basis molarcomposition of 8.5% CO, 10.5% CO2,0.5% O2 and 80.5% N2. The gas sat 620c and 1 atm with a dewpoint of 57c at a flow rate of1270mol/h.The gas is cooled to 425C by spraying water at 20C intothe gas.Assume that the spray unit is adiabatic .calculat therequired water feed rate in kg /h.
