A detailed excel sheet containing all Peng-Robinson calculations should be submitted. Some of the Peng-
Robinson calculations are to be done manually and not by Aspen Plus or any other process simulator/PVT software. PC-SAFT can be done using Aspen Plus or KBC Multiflash.

Group 4

1. Density of n-decane at 298.15 K and 1 bar using PR (Excel)
2. Fugacity coefficients of 1-butanol and n-butane in the vapor phase at x = 0.5 using PR (Excel)
3. Fugacity coefficients of diethyl ether and ethane in the vapor phase at x = 0.5 using PR (Excel)
