“…From Table 8, it follows that the implementation of the Zeoforming process allows increasing the octane number of the stable gas condensate. Specifically, the research octane number is increased by 17.8 points at the process pressure of 2.5 MPa, by 19.4 points at the process pressure of 3.5 MPa, and by 22.7 points at the process pressure of 4.5 MPa. In spite of the decrease in aromatic hydrocarbons content in the Zeoforming products, the octane number increases due to increase in high octane light n-paraffins and isoparaffins content.…”

Zeolites are used as catalysts for a wide range of industrial processes. Due to their microporous structure, the use of zeolites is limited to transformation of light feedstocks. At the same time, light products of oil extraction such as stable gas condensate are burned or returned to the oil reservoir for maintaining reservoir pressure, not being used as a feedstock for the secondary refinery. This work considers the use of the stable gas condensate as a feedstock for the Zeoforming process and the use of the obtained product as one of the blending components of commercial gasoline. After measuring main physicochemical properties and performance characteristics of the stable gas condensate, the Zeoforming process was implemented at a laboratory scale. The use of the stable gas condensate and Zeoforming products as blending components of gasoline was assessed. Applying the software program, recipes for the blending of gasoline were developed. It has been found that the Zeoforming process increases the octane number of the stable gas condensate, allowing for reduction of the gasoline production costs due to replacement of expensive additives.

The authors reviewed the statistics of winter diesel fuel consumption in the Russian Federation for 2000–2017, revealed a positive growth rate. On this fact, the relevance of the study was substantiated. The complexity and importance of the refining process leads to the need for digitalization of oil refineries. The object of the study is obtaining winter diesel fuel, taking into account transport costs. The subject of the study is digitalization of the oil refining process on the base of constructing the mathematical model for obtaining winter diesel fuel, taking into account delivery costs. Main research methods: retrospective data analysis, synthesis, comparison, linear programming methods. The authors considered two stages of winter diesel fuel production: dewaxing a mixture of stages of hydrocarbon raw materials on zeolite and subsequent compounding. For each stage, the authors compiled a system of equations describing the process. The authors also compiled a target function for obtaining winter diesel fuel, taking into account the costs of receiving and delivering. The obtained mathematical model can be used to ensure the required quality of winter diesel fuel (in terms of sulfur content, density and flash point).

The climatic features of Russia, as well as the need for the development of the Arctic and the Great Northern Sea Route, require an increase in the production of winter diesel fuel. The object of the study is obtaining winter diesel fuel. The subject of the study is digitalizing oil-refining processes by building the mathematical model of winter diesel fuel production for the case of combining dewaxing regimes taking into account the logistical aspect. Main research methods: retrospective data analysis, synthesis, comparison, optimization theory methods. A literary review was carried out, the main methods for improving the low-temperature properties of winter diesel fuel were revealed. Study hypothesis: a combination of dewaxing regimes will increase the yield of denormalizate and, accordingly, winter diesel fuel. The authors for each mode of dewaxing compiled a mathematical model. Then, the authors constructed a mathematical model of obtaining winter diesel fuel for a combination of dewaxing regimes and taking into account the logistical aspect. The obtained mathematical model can be used to obtain the required amount of winter diesel fuel with compliance with quality requirements and taking into account the logistical aspect.
