2. Inlet gas stream to a packed absorption tower (absorber) contains y1=0.04 mole fraction ammonia (NH3). The outlet gas stream contains y2=0.006 at 293K and 101.325kPa. The inlet solvent flow is L2=100kgmol/h and contains small amount of ammonia, x2=0.002. The total inlet gas flow is V1=75kgmol/h. The tower cross-sectional area is 0.5m2. The film mass-transfer coefficients are kxa=16.9102kgmol/sm3mol frac kya=7.39102kgmol/sm3molfrac The following figure on the next page shows the equilibrium and operating lines assuming dilute mixture. Using the given figure and the given data, determine the following: Part A) Interface concentrations at the bottom and top of the tower Part B) Evaluate (Must show equations and calculation in the answer sheet) Part C) Using the data for the bottom of the absorber, calculate the overall mass transfer coefficient Kxa and the percent resistances in the gas and the liquid films and the flux NA using Kxa. If required assume a=10m2/m3
