.A 5-stage countercurrent absorber is used to absorb acetone from air into water at 3 atm pressure and 20°C. The total inlet gas flow rate is 100 kmol/h. The inlet gas is 0.004 mole fraction acetone. The inlet liquid contains 0.0001 mole fraction acetone. Outlet gas is 0.0002 mole fraction acetone. Assume total liquid and gas flow rates are constant. At 20°C the Henry's law constant for acetone in water is H = 1.186 atm/(mole fraction). Find the liquid flow rate required and the mole fraction acetone in the outlet liquid.

Question
Transcribed Image Text:. A 5-stage countercurrent absorber is used to absorb acetone from air into water at 3 atm pressure
and 20°C. The total inlet gas flow rate is 100 kmol/h. The inlet gas is 0.004 mole fraction acetone.
The inlet liquid contains 0.0001 mole fraction acetone. Outlet gas is 0.0002 mole fraction acetone.
Assume total liquid and gas flow rates are constant. At 20°C the Henry's law constant for acetone
in water is H = 1.186 atm/(mole fraction). Find the liquid flow rate required and the mole fraction
acetone in the outlet liquid.
