Acetone is to be recovered from a 8 % acetone-air mixture by scrubbing with water in a packed tower using countercurrent flow. The liquid rate is 1.85 kg/m²s and the gas rate is 0.85 kg/m²s. The overall absorption coefficient Kça may be taken as 2.5 x 104 kmol/[m³s (kN/m²) partial pressure difference] and the gas film resistance controls the process. What height of tower is required tower to remove 95 % of the acetone? The equilibrium data for the mixture are: Mole fraction of acetone in gas Mole fraction of acetone in liquid 0.0099 0.0196 0.0361 0.0400 0.0076 0.0156 0.0306 0.0333

Question
Q2 Acetone is to be recovered from a 8 % acetone-air mixture by scrubbing with water in packed tower using countercurrent flow. The liquid rate is 1.85 kg/m²s and the gas rate is 0.85 kg/m²s. The overall absorption coefficient Kça may be taken as 2.5 × 104 kmol/[m³s (kN/m²) partial pressure difference] and the gas film resistance controls the process. What height of tower is required tower to remove 95% of the acetone? The equilibrium data for the mixture X are: Mole fraction of acetone in gas Mole fraction of acetone in liquid 0.0099 0.0076 0.0196 0.0156 0.0361 0.0400 0.0306 0.0333
