Question:

Water is used to remove CO2 from air by absorption in a column packed with Pall rings. At a certain region of the column where the partial pressure of CO2 at the interface is 150 psia and the concentration in the bulk liquid is negligible, the absorption rate is 0.017 Ibmolh-ft2. The diffusivity of CO2 in water is 2.0 x 10-5 cm2/s. Henry's law for CO2 is p = Hx, where H = 9,000 psia. Calculate:
(a) The liquid-phase mass-transfer coefficient and the film thickness
(b) Contact time for the penetration theory
(c) Average eddy residence time and the probability for the surface-renewal theory
