Q.7 Design a scrubber for absorbing acetone vapor from air acetone vapor mixture by using water as a pure solvent. The temperature in scrubber is 25°C and scrubbing is isothermal. Operating pressure of scrubber is near atmospheric. A mixture of air with acetone vapor containing 6% by volume of acetone is passed through the scrubber. The mixture contains 1400 m3/hr of air. The scrubber is required to absorb 98% of the acetone. At 25° C vapor pressure of acetone = 228.416 torr 05
