By means of a plate column, acetone is absorbed from its mixture with air in a
nonvolatile absorption oil. The entering gas contains 25 mole percent acetone, and
the entering oil contains 2 mole percent acetone. Of the acetone in the air, 95% is to
be absorbed, and the concentrated liquor at the bottom of the tower is to contain 10
mole percent acetone. The equilibrium relationship is
Ye= 1.9 xe
Construct the x-y plots for the equilibrium and operating lines using both mole
fraction and solute-free coordinates, and determine the number of ideal stages.
If stage efficiency is 90%, what is the number of real stages in the plate column?
