RESUMO:

Due to the large amount of compounds present in the crude oil, for example, hydrocarbons and carbon dioxide, knowledge of the thermodynamic properties of these mixtures is necessary in order to describe the behavior of process of industrial interest. Vapor-liqui equilibrium data is one of these properties required for the production of gasoline , diesel, naphtha, kerosene, among others. Secondarily, quantities of heat and work can be determined for these processes. For fluid, these properties are often evaluated from measurements of the molar volume as a function of temperature and pressure, providing relationships between pressure, volume and temperature (PVT), which can be expressed as state equations. This dissertation provided a data series of vapor/gas-liquid data found in the literature for mixture of CO2 and CH4 / C2H6 / C3H8 / C4H10 at various temperatures and pressures. Equation of state of Peng-Robinson (78) and van der Waals quadratic mixing rule (vdW1 - QMR / k) have been used to describe the experimental data sets. SPECS program has been used as computational tool. A quantitative description of the actual behavior of fluids has been obtained. Tests or simulation of the estimated parameters from the systematic data series has been provided, demonstrating the applicability of the cubic equation of state.
