A gas stream and a liquid stream are brought together in acolumn, and component A should be exchanged between the phases. Thebulk mole fraction of component A in liquid is calculated in onepart of the column.

and vapor are 0.18 and 0.45, respectively.

correspondingly The process is running at 298 K and 1atmosphere.

a) Determine whether the phase is absorption or stripping andclarify the difference.

b) Determine the molar fluxes by combining the film masstransfer coefficients with the total mass transfercoefficients.

the coefficients

c) Determine which step is in charge of the transferprocess.

At the operating conditions, the individual mass transfercoefficients for liquid and vapor phases were determined.

as a result of the required correlations;

k - 3 x 104 kmol A's m² mol frac =

k - 1.5 x 10 kmol A/s m mol frac

Within the operating range, the equilibrium relationship islinear and is written as y=1 8x, where y and x are the molefractions of component A in vapor and liquid, respectively.
