A gas stream containing 3% A is passed through a packed column to remove 99% of the A by absorption in HO. The absorber will operate at 25°C and 1 atm. and the gas and liquid rates are to be 0.0617 mol/m2.s and 0.309 mol/m2. respectively. Mass transfer coefficients and equilibrium data are given below y* =3.1x at 25°C Kya = 0.589 molm?.s key a = 0.147 molm?.s (a) Find Noy, Hoy, Z assuming isothermal operation and neglecting changes in gas and liquid flow rates. What % of the total resistance is in the gas phase? (b) Calculate Z using No and Hox.
