jet fuel

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.

The review and analysis of oxidation processes necessary for quality improvement of oil fractions boiling to 623 K have been carried out. Different oxidative technologies for crude oil processing have been examined. Their advantages and disadvantages have been shown.

The article deals with the development of technological scheme for refining oils extracted in Iraq. Basic characteristics and physico-chemical properties of Iraq oils have been considered. The main stages of oil refining and processing have been described. Material balances of each processing stage have been calculated.

The work is devoted to the development of alternative jet fuel blended with rapeseed oil-derived biocomponents and study of their physical-chemical properties. The modification of conventional jet fuel by rapeseed oil esters was chosen for this work among the variety of technologies for alternative jet fuels development. The main characteristics of conventional jet fuel and three kinds of biocomponents were determined and compared to the standards requirements to jet fuel of Jet A-1 grade.
