Transport property equations-of-state for reservior fluids and dense gas mixtures

Quantitative knowledge of viscosity and thermal conductivity at reservoir temperature and pressure of interest is required for many engineering problems that involve heat and mass transfer or pressure drop relationship. Direct experimental viscosity and thermal conductivity data are usually not available at reservoir temperature, pressure and composition of interest. Especially for mixture, it is very hard to get available experimental data because reservoir conditions are very different for every reservoir. Since thermodynamic and transport properties are based on molecular interactions, the application of the phenomenological relationship between the graphs of PVT and T灰P (and T竹P, 灰 denotes viscosity and 竹 denotes thermal conductivity respectively) is used to establish cubic equations-of-state for the predictions of transport properties over the entire PVT states, including dilute-gas viscosity, coexistence gas-liquid viscosities and high-pressure-dense fluid viscosity of pure substances, range from hydrocarbons (methane through n-octane), non-hydrocarbon (carbon dioxide, nitrogen), polar fluids (water, alcohols) and refrigerant fluids. Mixture blending rules that relate pure component parameters to composition of the systems are used to establish equations-of-state for mixture viscosity and thermal conductivity. The prediction results are in better agreement with measured data than the previously established transport property models.
