The jet and diesel fuels production line has been simulated using the universal simulating program ChemCad. The choice of the rectification process calculation module was substantiated. The Grayson-Streed and Lee Kesler models were used for the calculation of the thermodynamic system and the phase equilibrium of the multicomponent mixture. The model of an oil mixture distillation unit for jet and diesel fuels production has been developed.

The article deals with the determination of hydrodynamic parameters necessary to conduct the desulfurization process of straight-run kerosene (SRKF) and straight-run diesel fractions (SRDF) via oxidation of sulfuric organic compounds, followed by the removal of oxidation products. The established parameters which are characterized by the linear rate of the oxidant (air) movement and the dummy contact time between the oxidant and the feedstock allow the process to be carried out without stirring.
