Question

Question 1 (10 out of 10 A contaminant (A) is to be removed from air at 293 K and 1.013x1 05 Pa in a counter current packed tower which has a diameter of 0.6m. Pure water willl be used as the absorbent. The inlet gas flow rate is 80 mol.m2.s. Under these conditions the overall capacity coefficient (Kya) is assumed to be 80 molm3.s'AY. The mole fraction of the contaminant in air should be reduced from 0.071 to 0.004. The tower will operate at 293 K. Determine the height of the mass absorber where the inlet water flow rate is 102 mol.m2.s1? (The integral calculation should have at least 6 steps) The required equilibrium data is: 0.0455 X (kg mol A/ kg mol H20) 0.0164, 0.0252, 0.0349, 0.0722 Y (kg mol A/kg mol H20) 0.021, 0.032, 0.042, 0.053, 0.08
