Enthalpies of mixing for the binary gaseous system methane-carbon dioxide were measured by an isothermal flow calorimeter at temperatures of 293.15, 305.15, and 313.15 K, with mole fractions of methane ranging from approximately 0.2 to 0.8. For the first two isotherms, the measurements were made at pressures of 0.507, 1.115, and 1.520 MPa (5, 11, and 15 atm, respectively). For the third isotherm, measurements were made at pressures of 0.507, 1.013, 1.520, 2.533, 3.546, and 4.600 MPa (5, 10, 15, 25, 35, and 45.4 atm, respectively). The experimental results were compared with those already available in the literature, as well as with predictions based upon the following equations of state: Benedict-Webb-Rubln (BWR), Redllch-Kwong, and the Redllch-Kwong equation with the modifications proposed by Jacoby and Robinson.
