Absorption #2: Methyl Ethyl Ketone (MEK)-Oil Absorption By means of a plate column, methyl ethyl ketone is absorbed from its mixture with air in a non-volatile absorption oil. The entering gas contains 12 mole percent methyl ethyl ketone, and the entering oil is methyl ethyl ketone-free. Of the methyl ethyl ketone in the air, 98 percent is to be absorbed, and the concentration of the liquor at the bottom of the tower is to contain 5.0 mole percent methyl ethyl ketone. The equilibrium relationship is ye = 1.90 xe. Hint: Choose 100 moles of entering gas as a basis. (a) Plot the operating line and determine the minimum number of stages (graphically) for the equilibrium relationship provided. (b) Confirm the results of part (a) using the analytical Kremser equation.
