PE 5663 Natural Gas Utilization

1- Calculate the Z-factors and the molar volumes for pure CO2 at 150ºC and pressures 10, 20, 40, 60, 100, 300, 400 and 500 bar. Use the RK EoS.

2- Plot the results for Z-factors and molar volumes of CO2 vs P. 3- Plot the gas formation volume factor of CO2 vs P. 4- On the plots, compare the results obtained for the Z-factor and Bg from the RK EoS with

those reported in literature and discuss on the discrepancies.

Experimental data for Z-factor for pure CO2 at 150ºC:

P/bar Z 10 0.985 20 0.970 40 0.942 60 0.913 100 0.869 300 0.762 400 0.824 500 0.910
