Bubble-Point Measurements of n¿Butane + n¿Octane and n¿Butane + n-Nonane Binary Mixtures



Elisabeth Mansfield, Stephanie L. Outcalt


Mixtures of small gaseous hydrocarbons with longer chain hydrocarbons are of interest to the natural gas industry. In particular, binary mixtures of nonane are of particular interest, as nonane was just incorporated into the GERG-2008 equation of state, but there is little experimental vapor- liquid equilibrium (VLE) data available to support the equation. The bubble-point pressures of four compositions of each of the binary mixtures butane + octane and butane + nonane were measured over the temperature range of 270 K to 370 K. The data and the expanded uncertainty (at a 95 % confidence level, k=2) of each point is reported. Additionally, the data are compared to existing literature data and the GERG-2008 equation. This is the first report of vapor-liquid equilibrium measurements on butane + nonane binary mixtures.
