oper "Separation Process Principles" 4th Ed. - Ch 2, Ch 5 & Ch 6 Absorption: Acetone-Oil Absorption By means of a plate column, acetone is absorbed from a gas mixture using a non-volatile absorption oil. The entering gas contains 30 mole percent acetone, and the entering oil is acetone-free. Of the acetone in the air, 97.0 percent is to be absorbed, and the concentration of the liquor at the bottom of the tower is to contain 10.0 mole percent acetone. The equilibrium relationship is ye = 1.90 xe. a) Plot the operating line and determine the minimum number of stages. Hint: Choose 100 moles/hr of entering gas as a basis. b) If 100 moles/hr of entering gas is to be treated what is the minimum among of oil that must be used? Hint: This will be the condition in which an infinite number of stages are needed, e.g. the material balance (operating line) intersects the equilibrium line at the outlet design condition.
