Solubilities of Nitrogen in Selected Naphthenic and Aromatic Hydrocarbons at Temperatures from 344 to 433 K and Pressures to 22.8 MPa

The solubilities of nitrogen in selected naphthenic (cyclohexane and trans -Decalin) and aromatic (benzene, naphthalene, 1-methylnaphthalene, phenanthrene, pyrene) solvents were measured using a static equilibrium cell over the temperature range from 344.3 to 433.2 K at pressures to 22.8 MPa. The uncertainty in these measurements is estimated to be less than 0.001 in mole fraction. The Peng−Robinson equation of state was shown to represent the experimental data with root-mean-square deviations of about 0.002 when a single interaction parameter ( C ij ) is used for each binary system.
