摘要: New experimental data are presented for the vapor−liquid equilibria in binary systems nitrogen + methane, ethane, and methane ethane including saturated liquid densities covering a temperature range of 130 K to 270 pressures up 10.1 MPa. On basis new these mixtures, which may be regarded as model performance widely used group contribution equations state VTPR PSRK was investigated. These studies focused on equations' ability represent accurately over wide temperatures when constant volume translation applied.
