Compositions of first and second liquids in C₂H₆–C₃H₈-N₂ LL systems. The compositions calculated from experimental Raman spectra are represented by the open points, while the PC-SAFT calculations are shown as filled points. The x-axes show the initial mixing ratio of ethane for each experiment. The y-axes show the mole fraction of each species in the first or second liquid. Ethane concentrations are shown in red, propane in green, and nitrogen in blue.
