Volumetric properties of gas mixtures at low temperatures and high pressures by the Burnett method: The hydrogen-methane system

A Burnett type of apparatus for the study of the volumetric behavior of gases at low temperatures and high pressures was constructed. The apparatus was used to study the volumetric behavior of methane and four mixtures of hydrogen and methane from +50° to −200°F. and pressures as high as 7,000 lb./sq. in. The experimental data were used to obtain the second virial coefficients for pure methane and for the mixtures. The results of approximately 600 experimental points were used to obtain a table of compressibility factors for methane and the mixtures at even increments of pressure and temperture.
