Q2) A binary liquid mixture which is at 25C is to be rectified in a plate column operating at 1 bar. Feed contains equal moles of light and heavy key components and is pumped to the column at a flowrate of 36kmol/h through a partial vaporizer in which 20 mole percent of the feed is vaporized prior to column entry. The top and bottom products will contain 96 and 4 mole percent of light key component. The reflux ratio is chosen as 2.2. Calculate: a) The percentage recovery of light key component b) Number of theoretical stages c) Optimum location of the feed tray d) Condenser and reboiler loads in kW (Note: Use Figure 2; take average latent heat as 104kJ/mol for part d) Figure 2
