MATHEMATICAL MODELS OF THE RECTIFICATION COLUMN PROCESS IN THE OIL PROCESSING INDUSTRY

The article developed a mathematical model of a closed flow in a rotating pipe, which allows determining the distribution of axial and azimuthal velocities. Also, a mathematical model of the diffusion and rectification processes in the temperature field of the rectification column of a mini-oil refining unit has been developed, which allows determining the effective rectification regime. In addition, a model of diffusion and rectification processes, competing in oil separation, has been created, which allows predicting the volume shares of light fractions of petroleum products.
