Chapter 1

1.1 Dew point calculation
ST

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
noncondensable) at 1 atm
UV

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

, 1.2 Compressibility Factors
Fifty cubic meters per hour of methane flow through a pipeline at 40.0 bar absolute and 300.0
K. Estimate the mass flow rate.

UniSim solution (Fig. 1.3)

In the molar flow rate cell, set the volumetric flow rate to 50 m3/h.

1.3 Use of Raoult’s law
A liquid mixture contains 40 % (mole percent) benzene, and balance is toluene equilibrium
with its vapor at 30.0°C. What are the system pressure and the composition of the vapor? Use
Unisim, PRO/II, and Aspen Plus.
