SATURATION PROPERTIES OF OXYGEN NITROGEN MIXTURES

A correlation for the relative volatility of the oxygen-nitrogen system was developed using data available in the literature and previously unpublished Linde Company data. The heat contents of the saturated vapors and liquids were computed using an equation-of-state approach for the vapor heat content, and the latent heats as obtained from the Clausius-Clapeyron equation, to determine the liquid heat contents. The results were plotted for the pure gases and the mixtures at 10 increments as large scale graphs of relative volatility as a function of temperature and pressure, temperature-composition at fixed pressures, and a Mollier diagram of pressure versus enthalpy. All the charts extend from atmospheric to critical pressures. Author
