Consider the binary mixture of ethyl ethanoate (1) and n-heptane(2). The following are the properties of the system at 70°C: 2 In y₁ = 0.95x₂² P₁S sat = 79.8 kPa In y₂ = 0.95x₁² P₂sat = 40.5 kPa 1. Construct a Pxy diagram with yx diagram for the system at 70°C. Discuss if an azeotrope exists; if yes, determine the azeotropic composition and pressure. 2. Using the Pxy diagram, show that the system with overall composition z₁ = 0.2 exists as vapor and liquid phases in equilibrium at P = 55 kPa. 3. Perform a PT-flash calculation to determine the fraction of vapor in the system in part (2) and the vapor and liquid phase composition.

Question
Consider the binary mixture of ethyl ethanoate (1) and n-heptane(2). The following are the properties of the system at 70°C: 2 In y₁ = 0.95x₂² P,sat = 79.8 kPa In Y₂ = 0.95x₁² P₂sat = 40.5 kPa 1. Construct a Pxy diagram with yx diagram for the system at 70°C. Discuss if an azeotrope exists; if yes, determine the azeotropic composition and pressure. 2. Using the Pxy diagram, show that the system with overall composition z₁ = 0.2 exists as vapor and liquid phases in equilibrium at P = 55 kPa. 3. Perform a PT-flash calculation to determine the fraction of vapor in the system in part (2) and the vapor and liquid phase composition. 4. Verify your answer to the liquid and vapor phase composition in item (3) from the phase diagram. Apply ILAR on the phase diagram to verify your answer to the amount of vapor in the system. 5. From the given overall composition in part (2), plot the V (fraction vaporized) vs P (system pressure) diagram from its Pdew to Pbub using increments of 0.5 kPa.
