On correlation of physical-chemical and dynamic characteristics of hydrocarbon fluids
M.M. AsadovA method for the definition of characteristics of molecular weight-related hydrocarbons has been developed. The equation of state Soave–Redlich–Kwong was tested in binary systems with the participation of hydrocarbons. It was justified that Soave–Redlich–Kwong equation of state describes well data on the saturation pressure in a CO2 – CH4 system with average absolute deviation. An isoconcentration phase diagram of vapor-liquid equilibrium of the CO2 –CH4 system has been developed. It was established that the diffusion coefficient in the oil-fluid system of sub-and supercritical fluid components of CO2 (C2H6, C3H8) increases with pressure and tends to decrease as asphaltene content increases.
