Solutions Manual for Computer Methods in Chemical

Engineering, 1st Edition by Nayef Ghasem (All Chapters) A+
Chapter 1



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

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

below

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. Equation of state: Peng

Robinson.
