The article discusses the urgent problem of industrial methods for increasing the octane number that improve the quality of gasoline produced. These methods include the processes of catalytic reforming and compounding of gasoline. Reforming from "to reform" (English) — to remodel, to improve. Reformate, depending on the production technology and composition of the raw material, may contain up to 70 % of the mass. aromatic hydrocarbons. Attention to this problem is due to the tightening of environmental requirements for the quality of motor fuel that must comply with modern standards. An effective solution to this problem is to model refining processes with programming. In this article, we apply methods of correlation and regression analysis. Using these methods, you can establish the relationship between two or more variables, thus finding the most effective solution to both technological and economic issues.

The process of separating solid paraffins from heavy oil fractions is one of the most expensive and difficult to implement in oil refining. Dewaxing is usually carried out by the method of low-temperature crystallization of solid paraffins in the presence of a multiple excess of selective solvents. The search for other, simpler and inexpensive technologies for the isolation of solid paraffins is an urgent task. Some Russian scientists devoted their work to studying the possibility of dewaxing oil fractions in an electric field.These article deals with the influence of the main parameters of solid paraffin hydrocarbons electrodeposition in an electric field on the qualitative parameters of the process. It has been established that the shape of the electric field and the degree of its inhomogeneity don't affect the target indicators. Increasing the electric field strength to a certain limit leads to a decrease in the required time to complete the electrodeposition process. Increasing the process temperature leads to the release of higher melting paraffins. The complete release of solid paraffins in an electric field depends on the field strength, process temperature, type and concentration of the introduced additive.

The article discusses the results of a study on the selection of wax inhibitors that can be used at the Kondinskoye oil field during transportation and dehydration of the emulsion.Asphaltene precipitation is one of the most serious issues in oil production. The experiment was conducted in order to select the most effective wax inhibitors. We have carried out laboratory tests to choose the most effective wax inhibitor in the conditions of oil production, collection, preparation and external transport systems at the Kondinskoye oil field. Based on the data obtained, wax inhibitor-2, wax inhibitor-4, and wax inhibitor-6 have shown the best results in ensuring the efficiency of inhibition, which should be at least 70 %, and, therefore, they can be allowed to pilot tests. The recommended initial dosage of inhibitors according to the results obtained during pilot tests should be at least 500 g/t of oil.

The article deals with the results of a complex physical and chemical study of gas condensates. The research was carried out on gas condensates of the Pyakyakhinskoye gas condensate of productive formation BU18 in perforation intervals 3 153–3 277 m, 3 208–3 239 m, 3 455–4 060 m, 3 685–4 293 m, 3 781–4 429 m. Attention to this topic is due to the fact that this information is necessary for the calculation of reserves of natural resources, design, development of the field, and optimal technological solutions for its processing.

The article considers the results of the study on the selection of chemical reagents to improve the rheological properties of the oil emulsion of the Kondinskoye oil field during transportation and dehydration of the emulsion. The studies have been carried out on an artificial emulsion. We describe a method of determining demulsifying activity of a reagent at a certain temperature mode of a preliminary water discharge plant. In addition, we give the results of the study with various chemical reagents, select the optimal mode of emulsion preparation. This experiment was conducted in order to select the most effective demulsifiers to improve the technology and economics of the field and transportation process. The optimal choice of type of demulsifier, mode of its application and places of entry guarantee high quality of oil preparation. The following demulsifiers could be used in the process: DE-4, DE-6, and DE-9. The result of using these reagents is an optimal reagent flow rate per ton of fluid and a maximum amount of water separated from the emulsion over a certain time.
