## Abstract

A Generalized B-W-R Equation of State is tested for hydrogen which is a quantum gas and for systems containing hydrogen.

The gases and systems studied are: hydrogen, nitrogen-hydrogen methane-hydrogen and ethane-hydrogen.

The pressure is calculated using observed P-V-T data and the deviation is computed therefrom. For the pure gas, hydrogen, the generalized equation is compared against the original B-Vi-R equation. For mixtures, the Gunn-Chueh-Prausnitz method which is used to calculate the pseudo-critical conditions of the mixture is compared against the Prausnitz-Gunn method.

The ranges studied in this paper are as follows:pure hydrogen 30-773°K and 1 to 1200 atm., n itrogen-hydrogen 0-300°C and 25 to 1000 atm., methane-hydrogen -210 to 300°F and pressures as high as 3100 psi., and ethane-hydrogen 70-300°F and pressures as high as 3800 psi.

The results obtained with hydrogen demonstrate that the generalized B-W-R equation is valid for hydrogen at somewhat lower temperatures than the original B-W-R. Over most of the temperature range good results are obtained with either equation. However, at high pressures the original equation is more accurate.

A comparison of the Gunn-Chueh-Prausnitz(G-C-P)method with the Prausnitz-Gunn(P-G)method for the three binary systems yields essentially equivalent results in terms of average and maximum deviations from observed values.
