Mathematical Modeling of Diesel Fuel Hydrotreating

The principles of mathematical modeling of Hydrotreating diesel fuel in the representation of raw materials in the form of a set of narrow fractions in which the total content of various organosulphuric components is considered as a pseudocomponent are considered. As a result of the analysis of schemes of reactor blocks of Hydrotreating plants the most perspective two-reactor systems characterized by separate desulfurization of streams are revealed. It is shown that the preliminary fractionation of Hydrotreating raw materials into light and heavy fractions with the choice of the optimal boundary of fraction division can minimize the loading of the catalyst into the reactor unit. An algorithm for solving this problem, including experimental and computational fragments, is presented.
