Abstract:

The purpose of this work is to construct graphs of ITC and OI to analyze the dynamics of the system, as well as to identify the main characteristics of its operation. With the help of ITC, it is possible to identify long-term trends and changes in system performance, which helps in the strategic planning of oil production, refining and transportation processes directly depends on accurate knowledge of its thermodynamic properties. The flash evaporation curve is a key parameter that determines the behavior of oil at different temperatures and pressures. Construction of curves for Novoportovsk oil and its fractions based on data from the USSR oil collection, volume 4 to analyze the influence of fractional composition on thermodynamic behavior. As a result of the work, a single evaporation curve was constructed for Novoportovsk oil and its individual fractions. Analysis of the obtained graphs made it possible to identify patterns changes in thermodynamic behavior depending on the fractional composition. It was established how differences in the composition of fractions affect the shape and position of flash evaporation curves. The findings of the study demonstrate the possibility of using data from the USSR oil collection to construct reliable single evaporation curves.
