In the absorption of component A from an air stream into an aqueous stream, the composition of the two adjacent streams were analyzed to be CAL = 4.0 kmol/m3 and PAG= 1.013 x104 Pa. The Henry’s law constant for this system is 1.674 x 103 Pa/(kmol/m3). The overall liquid coefficient, KL, was equal to 1.26 x 10-6 kmol/m2.s. (kmol/m3). If 60 % of the total resistance of mass transfer is encountered in the liquid film [(1/kL)/ (1/KL) = 0.53], determine: i. The molar flux of A, (kmol/m2 s) ii. The liquid film coefficient kL, [kmol/m2.s (kmol/m3)] iii. The interfacial concentrations CAi (kmol/m3) and PAi(Pa) ) iv. The individual gas film coefficient, kG (kgmol/m2 s Pa) v. The overall gas film coefficient KG , (kmol/m2 s Pa)
