5 A packed-bed tower is used for absorption of sulfur dioxide (SO2) from an air stream using water as the solvent. At one point in the tower, the composition of SO2 is 10% (by volume) in the gas phase, and 0.30 wt% in the liquid phase, which has a mass density 61.8 lbm/ft?. The tower is isothermal at 30C, and the total system pressure is 1.0 atm. The convective mass-transfer coefficients are k = 2.5 lbmole/ft?. h(lbmole/ft) for the liquid . . PA CAL film, and kg = 0.125 lbmole/ft? . h. atm for the gas film. Equi- librium distribution data for the SO2-water-air system are provided in Problem 1. Plot out the equilibrium line in units of PA (atm) vs. CAL (Ibmole/ft). Plot out the operating point (PA, CAL) on the same graph. Determine P and and plot on the same graph b. Determine the gas-liquid interface compositions Pa, and CAL: Estimate Ko and Ku, Ky and K, at the operating point, and the molar flux NA: d. Determine the % resistance in the gas phase at the operating point. illis considering the feasibility of 2 r c. 5 A packed-bed tower is used for absorption of sulfur dioxide (SO2) from an air stream using water as the solvent.
