20. An acetone-air mixture containing 0.015 mole fraction of acetone has the mole fraction reduced to 1 per cent of this value by counter current absorption with water in a packed tower. The gas flow rate G, is 1 kg/m's of air and the water flow rate entering is 1.6 kg/m²s. For this system, Henry's law holds and ye = 1.75x, where ye is the mole fraction of acetone in the vapour in equilibrium with a mole fraction x in the liquid. How many stages are required? (Molecular weight for air 29 ,for water 18).

Question
Transcribed Image Text:20. An acetone-air mixture containing 0.015 mole fraction of
acetone has the mole fraction
reduced to 1 per cent of this value by counter current absorption
with water in a packed
tower. The gas flow rate G, is 1 kg/m's of air and the water flow
rate entering is 1.6 kg/m²s.
For this system, Henry's law holds and ye = 1.75x, where ye is
the mole fraction of
acetone in the vapour in equilibrium with a mole fraction x in
the liquid. How many
stages are required? (Molecular weight for air 29 ,for water 18).
