Development of Arctic Diesel Fuel with Optimal Composition

Abstract

The article offers the possibility of obtaining Arctic diesel fuel, which can be used at low temperatures. The physico-chemical properties of the resulting diesel fuel are also shown. New technical conditions were developed for a new type of Arctic diesel fuel. The main indicators of the quality of low-carbon diesel fuel are low-temperature properties, estimated by cloud point, temperature and temperature limit. New arctic fuel was obtained by adding a depressant. We used the depressor additives Keroflux and Difron. When selecting a depressor additive for a new grade of diesel fuel, it was necessary to take into account not only the composition of the fuel, but also the particular structure and composition of the additives themselves. Studies by many authors have shown that the solubility of additives based on copolymers of ethylene with vinyl acetate is lower than that of copolymers of vinyl acetate with alkyl methacrylate. The article also shows the possibility of obtaining basic fuel with a given pour point directly on the direct distillation of oil. An innovative jet hydraulic mixer was used to mix petroleum products, which provides intensive mixing of petroleum products in tanks and ensures stable quality of petroleum products during storage. Such technology allows to obtain winter and arctic varieties from summer diesel fuel by adding depressor additives.
