A liquid stream containing 50 mole % benzene and the balance toluene at 25°C with pressure 1 atm is fed to an evaporator at a rate of 2500 mol/s. The liquid and vapor streams leaving the evaporator are both at 95°C. The liquid contains 42.5 mole% benzene at 1000 mol/s and the vapor contains 73.5 mole% benzene. The exit streams are in the condition of 1 atm in pressure. i) Draw and label a flowchart of the process unit.

Question
Exercise – Non Reactive Energy Balance - 2 A liquid stream containing 50 mole % benzene and the balance toluene at 25°C with pressure 1 atm is fed to an evaporator at a rate of 2500 mol/s. The liquid and vapor streams leaving the evaporator are both at 95°C. The liquid contains 42.5 mole% benzene at 1000 mol/s and the vapor contains 73.5 mole% benzene. The exit streams are in the condition of 1 atm in pressure. i) Draw and label a flowchart of the process unit. ii) Calculate the heating requirement for this process in kW. (Use reference state: liquid, 25°C, 1 atm)
