Design a continuous distillation column (sieve plate) to recover acetone from a 10 % acetone (w/w) and water mixture available at 30C. The feed stream flow rate is 25,000 kg/h. The top product should contain at least 95 mole % acetone and the bottom product should contain <1 % acetone by mole. Consider reboiler as equivalent to one stage. This column is operated at atmospheric pressure (top tray). Column efficiency of 60% and pressure drop per plate of 1.25 kPa may be assumed. You can take the minimum liquid flow as 70% of the maximum rate both above and below the feed plate.
