Water is used to remove CO2 from the air by absorption in a column packed with Pall rings. At a
region of the column where the partial pressure of CO2 at the interface is 10.2atm and the
concentration of CO2 in the bulk liquid is negligible, the absorption rate is 1.88610-4mols-cm2.
The CO2 diffusivity in water is 2.010-5cm2s. Henry's law for CO2 is p=Hx, where H=612.0atm.
Calculate:
(1) Liquid-phase mass-transfer coefficient ) and film thickness (l)
(2) If the mass transfer coefficient on gas film (ky) is 0.05mols-cm2 and the total pressure of the
gas mixture is 51.0atm, calculate the overall liquid-side mass transfer coefficient, Kx.
