Abstract

To develop comprehensive models for multi-component natural gas mixtures (and other applications), it is necessary to have binary interaction parameters for each of the pairs of constituent uids that form the mixture. Good interaction parameters rely on a good collection of reliably collected data. In this work, we have carried out an exper- imental campaign to measure the bubble point pressures of mixtures of n-propane and n-decane, a mixture that has been thus far poorly studied. The experimental measure- ments of bubble point states span a composition range (in propane mole fraction) from 0.269 to 0.852, and the bubble point pressures are measured in the temperature range from 270 K to 370 K. These data, in conjunction with data from a previous publication on mixtures of butane + octane and butane + nonane, are used to determine binary in- teraction parameters. The newly-obtained binary interaction parameters represent the experimental bubble-point pressures given here to within 8%, as opposed to previous deviations up to 19%.
