Question 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=75kg mol/ /. 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 curve assuming dilute mixture. Using the given figure and the given data answer the following a. Draw the operating line. b. Determine Interface concentrations at the bottom and top of the tower x1i,y1i,x2i,y2i c. Evaluate the following: i. (yyi)M ii. Height (m) iii. Lmin d. Using the data for the bottom of the absorber, calculate the following: i. the overall mass transfer coefficient Kxa ii. The percent resistances in the gas and the liquid films and the flux NA using Kxa. "If required assume a=10m2/m3
