Optimization of the oil rectification process by the selection criterion of the light petroleum products

The article is devoted to solving the problem of increasing the yield of light oil products at the primary oil refining unit by the methods of mathematical and simulation modeling. An overview of the software packages for technological modeling used for petroleum refineries is given. An optimization criterion, that allows determining the maximum yield of light oil products is received, as well as restrictions on the process parameters are established. The adequacy assessment of the initial data dependence according to the Fisher criterion is given. A mathematical model of the petroleum distillation process for low-capacity installations is obtained. The model can be useful at optimizing the variable composition and consumption of raw materials (petroleum) according to the selection criterion for light oil products, taking into account seasonal requirements for the quality of petroleum products. The use of the proposed optimization criterion and the mathematical model on small-capacity oil distillation units improves the efficiency of process units.
