Q5 Solut (A) is being absorbed from a mixture with an insoluble gas in a falling film of water at 30 oC and a total pressure of 1.45 bar. The gas phase mass transfer coefficient at a given gas velocity is estimated to be Kc= 90.3 kmol/h. m2 (kmol/m3). It is known that 13.5% of the total mass transfer resistance lies in the gas phase. At a particular section of the equipment, the mole fraction of the solute in the bulk gas is 0.07 and the interfacial concentration of the solute in the liquid is known to be 0.002 . the equilibrium solubility of the gas in water at the given temperature is: P = 3.318*104 x
(P) is the partial pressure of (A) in the gas mmHg and (x) is the solubility of (A) in water in mole fraction. Calculate:
a) the absorption flux of the gas at the given section of the apparatus.
b) the bulk liquid concentration at that section.
c) the overall liquid phase mass transfer coefficient.
