“…The models based on superficial liquid velocity have been extensively used by various researchers to simulate three-phase experimental reactors [16,[24][25][26]. The same approach has been followed in this work in order to simulate hydrodesulfurization and hydrodemetallization of heavy crude oil.…”

“…Organonitrogen compounds in petroleum feedstock undergo hydrodenitrogenation to form ammonia and liquid hydrocarbon [28,29]. Between alkyl amines, quinoline is one of the most relevant nitrogen compounds in VGO of which seven molecules of hydro- gen per nitrogen atom are needed to convert it to a hydrocarbon liquid within the boiling range of naphtha cut [27].…”

A 4-lump kinetic model including hydrogen consumption for hydrocracking of vacuum gas oil in a pilot scale reactor is proposed. The advantage of this work over the previous ones is consideration of hydrogen consumption, imposed by converting vacuum gas oil to light products, which is implemented in the kinetic model by a quadratic expression as similar as response surface modeling. This approach considers vacuum gas oil (VGO) and unconverted oil as one lump whilst others are distillate, naphtha and gas. The pilot reactor bed is divided into hydrotreating and hydrocracking sections which are loaded with different types of catalysts. The aim of this paper is modeling the hydrocracking section, but the effect of hydrotreating is considered on the boundary condition of the hydrocracking part. The hydrocracking bed is considered as a plug flow reactor and it is modeled by the cellular network approach. Initially, a kinetic network with twelve coefficients and six paths is considered. But following evaluation using measured data and order of magnitude analysis, the three route passes and one activation energy coefficient are omitted; thus the number of coefficients is reduced to five. This approach improves the average absolute deviation of prediction from 7.2% to 5.92%. Furthermore, the model can predict the hydrogen consumption for hydrocracking with average absolute deviation about 8.59% in comparison to those calculated from experimental data.

Abstract:For the reliable design of crude oil and residua fractionators and fired heaters, accurate calculation method for ASTM Distillation curves and ASTM distillation temperature at the required volume percentage distilled is necessary. The present work deals with fitting literature data of ASTM Distillation curves and obtain a new correlation suitable to use in modeling when optimizing the refining processes, such as distillation, FCC, catalytic reforming, hydrotreating, etc. The results showed that the values predicted by the new correlation are in very close agreement with literature data and the range of mean overall deviation (%MOD) is (0.305-0.585). Also a shortcut correlation is presented to calculate the ASTM distillation temperature at the required volume percentage distilled. Based on temperatures obtained we can have an estimate of the heating costs involved to perform distillation and temperature at which different cuts are obtained.
