Question: Gas A is absorbed from a gas mixture stream using a nonvolatile Solvent (B) in a countercurrentabsorber. The tower is maintained at 300K and 100kPa.
Gas A is absorbed from a gas mixture stream using a nonvolatile Solvent (B) in a countercurrentabsorber. The tower is maintained at 300K and 100kPa. At a point in the absorption tower, the bulk gas mole fraction of A,yA is 0.03 and the bulk-liquid mole fraction of A x A is 0.01. The mass transfer coefficients kL is 0.5cm/s. The gas film resistance is 75% of the overall resistance to mass transfer. The equilibrium line is given by the linear equation: yA=1.5xA. The molar density of the solution is practically constant at 55 gmol/lit. Calculate: a) the mass transfer coefficients kG, KG, kx, Kx, ,ky , and Ky . b) the molar flux of gas A transferred to the liquid NA . c) the interfacial concentrations pA,i and CAL, i. b) the molar flux of gas A iransferrad to the liquad
