Carbon dioxide is absorbed in water at 25oC and 1 atm in a packed column. For this system it may be assumed that 88% of the resistance to mass transfer occurs in the liquid film and the overall coefficient, based on the gas film resistance, KG = 0.95 kmol/(m2h atm). For a dilute solution of CO2 in water, the equilibrium can be expressed in terms of Henry’s Law: pA= HA*xA where HA= 1.42*103 atm/mole frac. at 25oC and pA is in atm. Calculate kG’, Ky’,ky’ and Kx’.
