A saturated liquid feed with feed flow rate of 200 mol/h contains 42 mol% heptane and 58 mo1% ethyl benzene is at its boiling point. This feed is to be distilled at 101.32kPa to produce a distillate containing 97 mol% heptane and bottoms containing 98.9 mol% ethyl benzene. The reflux ratio is 2.5. a. (10 points) Plot the equilibrium curve (ya vs xa) and T-x, y diagrams using Antoine equation to determine the vapor pressures and using Raoult's law and Ideal gas law to find vapor- and liquid phase mole fractions. b. (10 points) Draw the operating lines for the rectification and stripping sections. Show feed line.
