,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.

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.
