“…The article [29] considers the conditions for the continuous operation of road vehicles in the Arctic due to the fuel system modernization and changes in the composition and type of fuel. It is shown that, due to additional operations, the fuel used in the Arctic is more expensive, and when operating at low temperatures, vehicles must be equipped with additional systems (filter electric heating, fuel intakes, etc.).…”

The Russian Arctic development is an investment direction, which is planned through a system of so-called “support zones” of various development degrees, it is a priority for Russia and can have a positive effect. Since integrated territorial development is associated with significant cargo flows of raw materials, materials and goods, logistics chains will include various transport modes, which will lead to the development of infrastructure (including the construction and reconstruction of seaports, the network of the railways and roads expansion) and the emergence of new international transport corridors (ITCs). A scientifically based solution to the problems of constructing a delivery route, including the location of transshipment points, logistics terminals and the rolling stock selection, will ensure the sustainable territories development through which ITCs pass. However, these tasks, which constitute the activity of organizing multimodal transportation, are associated with various types of risks, the successful solution of which, in this case, depends on the sustainable territorial development of these territories. Therefore, the research objective is to establish the relationship between the development of transport networks and the development of the Arctic region, the designation of possible prospects for the development of both multimodal transportation as a whole as a strategic event, and the contribution of each kind of transport, as well as the risks of creating and using international transport corridors, including cumulative impact on the environment. As a result of the literature analysis, we have considered the causes and consequences of the improper planning of supply chains and infrastructure, then we have indicated the role of new transport corridors in the development of territories. We have built a tree of problems in order to systematize risk situations and identify root causes and consequences. A method for calculating the cargo delivery time is proposed, taking into account the multimodality of logistics chains as well as measures that help reduce risks.

“…However, these methods are quite labor-intensive and inevitably lead to deterioration in the quality of the resulting fuel and noticeable losses of the target product [6]. To date, one of the most effective and cost-effective ways to improve the low-temperature characteristics of diesel fuel is the addition of depressant additives; this method is especially relevant when it comes to fuel production in mini refineries and remote areas [4,7]. According to statistics [8], the additives market in regions such as North America, Asia-Pacific, Europe, South America, the Middle East, and the Africa will grow by 5.11% per year from 2022 to 2029.…”

Diesel fuel is the main fuel for transport and power generation for remote areas, especially the Arctic. For these territories, it is important to produce low-freezing fuel grades. The most effective way to improve the low-temperature properties of diesel fuels (cloud point, pour point, and cold filter plugging point) is the use of depressant additives. Existing research shows that the depressant additives’ effectiveness is influenced by many factors. The most important factors are diesel fuel composition, additive concentration, and the temperature of additive introduction into the fuel (adding temperature). The purpose of this work is to find ways to increase the efficiency of depressant additives for the production of low-freezing diesel fuels by choosing the most effective additive concentration and adding temperature for fuels of various compositions. During the work, low-temperature properties were determined and the effectiveness of three depressant additives was assessed on four samples of diesel fuel at four concentrations (0.5, 1.0, 2.0, and 5.0 c.u., where c.u. (conditional unit) is the concentration recommended by the manufacturer of the additives). In addition, low-temperature properties for blends of six depressant additives and two samples of diesel fuel at five adding temperatures (15, 25, 35, 45, and 55 °C) were determined. In this work, in contrast to existing works, it was established for the first time that the composition of the fuel affects not only the depressant additives effectiveness, but also the dependence of the additive effectiveness on the concentration in which it is used. It is shown that the higher the content of paraffins in the composition of the diesel fuel, the less the depressant additive’s effectiveness in relation to cold filter plugging point depends on the concentration and the more the depressant additive’s effectiveness in relation to the power point depends on the concentration. An inverse relationship was revealed for the content of aromatic hydrocarbons in diesel fuel. It was also found for the first time that an increase in the adding temperature of depressant additives up to 35–55 °C enhances the effectiveness of their action in relation to the cold filter plugging point (maximum at 6–7 °C). It is shown that the greater additive effect on the cold filter plugging point of the diesel fuel, the more strongly the depressant effectiveness depends on the adding temperature. The work provides recommendations for obtaining the most low-freezing classes of fuel based on the samples considered. The regularities identified in the work will make it possible, depending on the composition of the fuel, to select the optimal concentration of the additive and the temperature of its adding, which will increase the efficiency of the additives, as well as the volume of low-freezing grades of diesel fuel production.
