Title: Excess molar volumes for CO sub 2 -CH sub 4 -N sub 2 mixtures

Abstract

Vibrating-tube densimetry experiments are being performed to determine the excess molar volumes of single-phase CO{sub 2}-CH{sub 4}-N{sub 2} gas mixtures at pressures as high as 3500 bars and temperatures up to 500{degrees}C. In our initial experiments, we determined the P-V-T properties of: (1) CO{sub 2}-CH{sub 4}, CO{sub 2}N{sub 2}, CH{sub 4}-N{sub 2}, and CO{sub 2}-CH{sub 4}-N{sub 2} mixtures at 1000 bars. 50 {degrees}C: and (2) CO{sub 2}-CH{sub 4} mixtures from 100 to 1000 bars at 100{degrees}C. Excess molar volumes in the binary subsystems are very accurately represented by two-parameter Margules equations. Experimentally determined excess molar volumes are in fair to poor agreement with predictions from published equations of state. Geometric projection techniques based on binary system data yield from published equations of state. Geometric projection techniques based on binary system data yield calculated excess molar volume for CO{sub 2}-CH{sub 4}-N{sub 2} mixtures that are in good agreement with our experimental data. 7 refs., 8 figs.
