REVIEW, EVALUATION, AND CORRELATION OF THE PHASE-EQUILIBRIA, HEAT OF MIXING, AND CHANGE IN VOLUME ON MIXING FOR LIQUID-MIXTURES OF METHANE + ETHANE

The available experimental data for liquid‐vapor equilibria, heat of mixing, and change in volume on mixing for the methane+ethane system have been reviewed and where possible evaluated for consistency. The derived properties chosen for analysis and correlation were liquid mixture excess Gibbs energies, Henry’s constants, and K values. Data sets, selected on the basis of the consistency tests applied, were correlated as functions of temperature and composition to provide internally consistent sets of property values suitable for engineering design calculations. © 1979, American Institute of Physics for the National Institute of Standards and Technology.
