Water is used to remove CO2 from 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 150 psia and the concentration in the bulk liquid is negligeable, the absorption rate is 0.017 lbmol/h.ft2. The CO2 diffusivity in water is 2 x 10-5 cm2/s. Henry's law for CO2 is p=Hx, where H=9000 psia. Calculate: A) Liquid-phase mass transfer coefficient and film thickness B) Contact time for the penetration theory C) Average eddy residence time and probability distribution for the surface- renewal theory
