An existing experimental apparatus was modified for the determination of bubble point pressures for binary mixtures of methane in paraffinic, naphthenic, and aromatic solvents at temperatures from 311 to 433 K and pressure to 113 bar. Precise bubble point data were obtained for methane binaries involving n-C??, n-C??, n-C??, n-C??, n-C??, cyclohexane, t-decalin, benzene, naphthalene, phenanthrene, and pyrene. The solvents n-C??, n-C??, n-C??, n-C??, n-C??, naphthalene, phenanthrene, and pyrene are solid at room temperature. Correlative efforts for methane + n-paraffins (C? and above) and methane + naphthenes and aromatics included: (1) Interaction parameters were determined for Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state using least squares regression of bubble point pressure data. (2) Several generalization schemes have been implemented for the SRK and PR interaction parameters in terms of pure hydrocarbon properties to extend the predictive capabilities of these equations to binary mixtures of methane + hydrocarbon solvents. (3) The new data and the data found in the literature were analyzed using the Krichevsky-Kasarnovsky model. This provided estimates of Henry's constants and infinite-dilution partial molar volumes of methane and demonstrated the internal consistency of the acquired data.Chemical Engineerin
