Efficiency Improvement of the Light Gasoline Fractions Isomerization by Mathematical Modeling

Optimization and forecasting of light gasoline fractions isomerization is a complex technological issue, as it includes a variety of factors and independent parameters. The most effective solution is to use the mathematical modeling method of physical and chemical laws of the process. In this paper, we propose a method of intensification of the combined fractionation and isomerization processes of pentane-hexane fraction with the aim to improve the service durability of the catalyst SI-2 on the L-35-11 / 300 production unit. The developed complex mathematical model takes into account the influence of the feedstock composition, allows for assessment of the catalyst current activity and it is also a powerful optimization tool. According to the survey results the optimizing the feedstock composition will increase the octane number of the isomerate at 1.6-2.2 points

Strategy of transition to advanced digital intellectual production technologies of catalytic processes of transformation of hydrocarbon raw materials

In the gasoline preparation process, various products are used, such as catalytic reforming, isomerization, hydrocracking, hydrodewaxing, catalytic cracking, liquidphase catalytic alkylation processes, as well as additives such as gasoline. As a result of the catalytic activity of a bifunctional catalyst in isomerization and aromatization reactions. The yield of liquid products (C[5+]), the composition of the reformate and the octane number can be adjusted by optimizing the independent variables (temperature, pressure, consumption of raw materials) or by adding different promoters to the reaction catalytic zone (water, chlorine). Optimization of this process is a very complex multi-stage technology for processing hydrocarbon feedstock into high-octane components, and increasing its efficiency reduces the cost of the product

Development of a Two-Fluid Hydrodynamic Model for a Riser Reactor

ANSYS Fluent is used to examine the mixing of catalyst zeolite particles with petroleum feedstock and water vapor in a fluid catalytic cracking (FCC) riser. A two-fluid model is developed for tracking catalyst particles and gas mixture in a riser, modeling the granular and gaseous phases as two interpenetrating continua. The hydrodynamic flows are analyzed with the aim to single out the principal physical effects that determine the distribution of particles. The results are compared with a study that is based on a non-isothermal reactive model. It is demonstrated that the simplistic purely hydrodynamic model generates similar flow fields. The developed model is valuable for improvements of modern FCC risers. The model is applied for understanding the hydrodynamics of an S-200 KT-1/1 industrial unit
