A single-stage liquid/vapor separation for the unknown molecule (1) and molecule (2) mixture with mole fraction z1=0.75 is operated at T=100°C and P=40 kPa. Determine the partial pressure of molecule (1) in the separator. The feeding rate of the mixture is 1mole/s and the molar fraction (V) of the vapor formed is 0.5. Saturated pressure of the molecule (1) is 50.00 kPa and that of the molecule (2) is 20 kPa at the separator temperature. Assume Raoult’s law applies. (8 points)

A liquid mixture of two unknown liquids, A and B, has a total vapor pressure of 0.04 bar. The vapor pressure of pure A under the same conditions is 0.03 bar, and the vapor pressure of pure B under the same conditions is 0.05 bar. Using Raoult’s Law, what are the mole fractions of A and B in solution?

An isothermal flash unit is to be used for the separation of any mixture into liquid and vapor streams at equilibrium. The composition of the streams depends on the quantity of the feed vaporized (flashed). If the vapor-liquid equilibrium relationship is expressed in terms of equilibrium constants; develop the mathematical model and calculate the portion of vapor stream to the feed stream, f=V/F using Bisection method just 3 iterations. The compositions in the feed (zi) and equilibrium constants at this...

An experiment on the vapor-liquid equilibrium for the methanol (1) + dimethyl carbonate (2) system at 337.35 K provides the following information: x1 = 0.0, y1 = 0.0 and P = 41.02 kPa x1 = 0.20, y1 = 0.51 and P = 68.23 kPa x1 = 1.0, y1 = 1.0 and P = 99.91 kPa Use this information to estimate the system pressure and vapor-phase mole fraction when x1 = 0.8. Use the 1-parameter Margules equation.
