1.1 Dew point calculation
Calculate the temperature and composition of a liquid in equilibrium with a gas mixture
containing 10.0 mol% benzene, 10.0 mol% toluene, and balance nitrogen (considered
UV

noncondensable) at 1 atm

UniSim solution (Fig. 1.1)
The liquid at equilibrium with its gas mixture is at the dew point, setting the vapor/phase ratio
to 1. The pressure is 1 atm, and as the basis, set the molar flow rate to 1 kgmol/s
The temperature is 51.1oC. The compositions of the vapor and liquid are shown in the figure
