Detailed Modelling of Hydrocarbonaceous Media Separation Process

Article Preview

Abstract:

This paper presents the results of a detailed study of the separation process in the range of characteristic values temperature (Т ≅ 0 ÷ 70 °C) and pressure (P ≅ 50 ÷ 700 kPa). The critical analysis of hydrocarbonaceous media separation process problem is made within functioning processing equipment on objects of the “Vyngapurovskoe” oil field in Russia. Modelling of first stage separation process is illustrated from data of reservoir fluid with detailed characteristic of evolution some components concentration into off-gas in dependence of temperature and pressure. Recommendations to the calculation of the component composition of hydrocarbonaceous fluids under the provisions of equilibrium thermodynamics using the model of Peng-Robinson are extradited. It has been established that the heavy hydrocarbons (С4+higher) concentration decreasing into off-gas theoretically could be achieved up to 48.41%.
