It is desired to strip acetone from an acetone-water mixture into an air stream The system operates isothermally at 20 °C and a total pressure of 300 mm Hg. The

inlet air is pure. The column operates at L/V = 2.5 The entering liquid concentration is 1 mol% acetone and the measured outlet liquid concentration is 0.03 mol% acetone. Assume that equilibrium is of the form y = mx Assume dilute system. Determine the concentration of acetone in air (in mol%) leaving the stripping column.
