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. Atmospheric tube (AT) is designed to separate oil into a group of light petroleum products (Tb <350 oC) and fuel oil as a residue. In this case, 2 main separation schemes can be used: 1 - single-column separation scheme (used when the content of light (C1-C4) is up to 1.2%, light - up to 45%); 2 - two-column scheme (increased content of light and light). In the domestic industry, the second scheme has become more widespread. They have greater flexibility (less sensitivity to the composition of the processed oil) and provide a greater (by 2%) selection of light ones.
