Q2: Acetone is to be recovered from a 5 per cent acetone (CH,COCH,)-air mixture by scrubbing with water in a packed tower using countercurrent flow. The liquid rate is 0.85 kg/m's and the gas rate is 0.5 kg/m's. The overall absorption coefficient Koa may be taken as 1.5x 10 kmol/[m's (kN/m2)] at P 101.3kN/m² and the gas film resistance controls the process. What height of tower is required tower to remove 98

Question
Q2: Acetone is to be recovered from a 5 per cent acetone (CH,COCH,)-air mixture by scrubbing with water in a packed tower using countercurrent flow. The liquid rate is 0.85 kg/m's and the gas rate is 0.5 kg/m³s. The overall absorption coefficient Koa may be taken as 1.5x 10 kmol/[m's (kN/m²)] at P= 101.3kN/m² and the gas film resistance controls the process. What height of tower is required tower to remove 98 per cent of the acetone? The equilibrium data for the mixture are: 0.0196 Mole fraction of acetone in gas 0.0099 Mole fraction of acetone in liquid 0.0076 0.0156 0.0361 0.0306 0.0400 0.0333
