Question

In a mass transfer apparatus operating at 1 atm. the individual

mass transfer coefficients have the following values

kx = 22 kmol/ m2

. h (Δx = 1)

ky = 1.07 kmol/ m2

. h (Δy = 1)

The equilibrium compositions of the gaseous and liquid phases are

characterized by Henry’s law:

p = 0.08 x 106

x, mm of Hg

(i) Determine the overall mass transfer coefficients Kx and Ky.

(ii) Determine the ratio of diffusional resistances of the liquid and gaseous

phases.
