Complex System for Gasoline Blending Maintenance

Abstract

The main aim of the study is to increase the efficiency of gasoline blending process using developed complex modeling system, it provides counting feedstock changes in the refinery, influencing detonation characteristics of trade gasoline. Final products of modeling system are precise and gasoline blending recipes are economically optimal. The relevance of the study is caused by the need to increase production volumes of trade gasoline in refineries that meet gasoline quality standards. Mathematical modeling and application of automatic computer systems are most relevant solutions for optimization of technologically difficult stages of oil production. The study considers the modeling approach to the blending process from the position of non-additivity of gasoline octane numbers. Practical results: The module of gasoline detonation characteristics developed in Borland "Delphi 7" workspace in conjunction with the module of chromatographic data analysis "Unichrom" and optimal recipes development module are combined in the universal complex system for gasoline blending process maintenance. The system allows taking into account feedstock composition changes on purpose to vary the recipes of trade gasoline blending. The developed complex system analyzes refinery conditions and recommends the feedstock supply in the process and allows getting essential economic benefit for the refineries by reducing the quality reserve of trade products

Study of the refractive index of gasoline+alcohol pseudo-binary mixtures

“…Refractive index of gasoline components, as hydrocarbons from paraffins, naphtenes, olefins and aromatics groups, together with other hydrocarbons properties, can be used to predict the octane number of the gasoline. Also, it can be used to develop blending recipes for commercial gasoline that meet quality standards requirements [11] and to assess the quality of this petroleum product [12]. The experimental determination of refractive index can be easily and rapidly done with a proper accuracy using small amounts of sample.…”

Application of Information Systems Integration for Blending Efficiency Improvement

“…Одним из основных путей, направленных на комплексную крупномасштабную оптимизацию производства, является интеграция таких цифровых систем в единое информационное пространство [4]. Цифровизация производства требует значительных усилий: во-первых, в построении адекватных математических моделей [4,5]; во-вторых, в разработке информационных технологий на основе системного подхода [6,7]; в-третьих, существенных затрат времени специалистов различного профиля. Совершенно не очевидно, что затраченные усилия смогут быстро окупиться.…”
