Q1-35 pts. The TXY diagram below shows the non-dieal behavior of the mixture of benzene and ethanol. The non-ideal behavior is so pronounced that the dew and bubble point curves intercept in the middle of the diagram, at about 45 mol% ethanol. This intersection point is called an azeotrope. Azeotropes are often undesirable because they prevent the of simple distillation as a process to separate the components. considering the diagram complete the shaded boxes (it is encouraged, for partial mark considerations, that you draw any relevant points in the diagram). you can assume that the pressure of the system is 1 bar. Q1-1, the dew point of a 20% ethanol solution is Q1-2, the bubble point of a 20% ethanol solution is Q1-3, flashing 100 mol/s of a 20% ethanol solution @70C, the ethanol mol fraction in vapour is Q1-4, flashing 100 mol/s of a 20% ethanol solution @70C, the ethanol mol fraction in liquid is Q1-5, flashing 100 mol/s of a 20% ethanol solution @70C, the molar flow of vapour is Q1-6, flashing 100 mol/s of a 20% ethanol solution @70C, the molar flow of liquid is Q1-7, The maximum temperature of a total condenser for a 90% ethanol stream is Benzene 0.35 Celsius Celsius 37.5 mol/s mol/s Celsius Ethanol Temperature C 70 70 75 75 55 65 80 80 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 Mole fraction of Ethanol Q1-35 pts.
