our aim is to separate a component A froma gaseous mixture of air using an absorption column. Theliquid solvent fed to the column is water at 20\deg C. At some specific location within the column, you measure the concentration of component A in the gas and liquid phases in terms of mole fractions as 0.35 and 0.05, respectively.The gas phase based overall mass transfer coefficient of component A in air is known, and it is equal to Ky=2.37 x10-3mol/m2.s.mole fraction. Equilibrium relation of component A in the gas phase and liquid water is given below. It has been found that 35% percent of the total resistance to mass transfer is in the liquid phase. Assume evaporation of water is neglected and calculate the film mass transfer coefficients in both phases (kxand ky), the local gas A mass-transfer flux (NA), and the interface mole fractions (xAiand yAi). Equilibrium curve equation : yAe =1.05 xAe [0.9+1.2 xAe (3.65 xAe-1)]
