solve a,b,c please
For the safe handling of a feed mixture with composition of 10, 20, 30, and 40 mol % of n-propane, n-butane, n-pentane, and n-hexane respectively, you are required to know the following unknown properties. Using De-Priester charts calculate the: Bubble point temperature at 700 kPa and the molar composition of the first bubble of vapour. Dew point temperature at 700 kPa and the molar composition of the last bubble. What fraction of the mixture is vapour when the pressure and temperature are 700 kPa and 100 degree C respectively? What are the compositions of the equilibrium vapour and liquid phases?Explanation / Answer
A) for bubble point, at 700 Kpa;
Component [Pressure] Pi at 100C Ki = Pi /1.2 Xi Yi = Ki Xi
n-propane 2.6 2.16 0.1 0.216
n-butane 0.78 0.65 0.2 0.13
n-pentane 0.35 0.29 0.3 0.09
n-hexane 2.70 2.23 0.4 0.736
B) for Dew point, at 700 Kpa;
Component [Pressure] Pi at 100C Ki Yi Yi/Ki
n-propane 2.6 2.16 0.216 0.10
n-butane 0.78 0.65 0.13 0.20
n-pentane 0.35 0.29 0.09 0.31
n-hexane 2.70 2.23 0.736 0.33
