Abstract: The article is devoted to the study of the issue of increasing and achieving the maximum possible yield of straight-run kerosene (semi-finished product of TS-1 jet fuel grade) from pipeline oil, typical for the center of the European part of the Russian Federation. Jet fuel is the most marginal of the mass products of oil refineries, the demand for which will only grow. The cost of the most spread grade of jet fuel TS-1 has currently reached a record price of 85 thousand rubles per ton. Compounding of narrow 10-degree fractions of kerosene has been performed. It is shown that the maximum possible yield of straight-run kerosene at AVT (atmospheric vacuum pipestill unit) is 16.57%, while the leader of production Slavneft-YANOS PJSC has reached only 11%. It is shown that the reason for this is the selection of the majority of kerosene fractions of 130-190 °C in the preliminary topping column K-1 of the AVT unit, which excludes their entry into the main column K-2, where straight-run kerosene is selected. Modified schemes of the AVT units are given, allowing to eliminate the shortcomings of the traditional process and to achieve the maximum possible yield.
Keywords: jet fuel TS-1, primary oil processing unit, hydrodemercaptanization, properties of narrow fractions.
