The purpose of research, design and design work by specialists of SAPR-NEFTEORGHIM LLC is to introduce into production an industrial process of joint processing of gasoline fractions mixed with oxygen-containing compounds (alcohols C1C6 methanol, ethanol, propanols, butanols, amyl alcohols) on a zeolite-containing catalyst. In the course of research work, a result was obtained that made it possible to select the optimal composition of the catalyst based on zeolite type ZSM-5. The introduction of this process into the technological scheme of petrochemical and oil refining enterprises makes it possible to obtain from gasoline raw materials components of class 5 gasoline containing individual benzene in its composition no more than 1,0 % by volume, aromatic hydrocarbons (in total) no more than 35 % by volume, olefins no more than 18 % by volume.
The technology (technological installation) makes it possible to obtain a concentrate of aromatic hydrocarbons by changing the temperature regime and the ratio of raw materials.

The analysis of use of rotary-disk devices in the processing of secondary petroleum products

Dmitry E. Suhanov, Anton V. Stepykin, Alexander E. Kuznetsov, Vladimir M. Ulyanov, Vadim A. Dikov, Artem S. Novoselov, Elena S. Kotlova, Alexander A. Shepalov

Features of calculation and selection of the equipment for a stage of cleaning for production of non-carcinogenic oils of plasticizers for tires, rubbers and plastics are stated. As a result of the study of the purification technique, it was found that it is inefficient to regenerate the oil according to traditional schemes in the presence of a solid phase dispersed into a liquid. In this regard, a rotary-disk type device was added to the cleaning scheme. It is shown that the process limits the kinetic region, so the delay time of particles in the sections of the apparatus will be the decisive factor. The dependences and methods for theoretical and experimental analysis of the performance of the device are proposed. As a result of the research, recommendations were also obtained that can be applied in the operation and development of technological adsorption equipment.

Features of coke formation on organically modified zeolite catalysts of oil refining

Elena A. Zelenskaya, Tatiana V. Zelenskaya, Aleksandra A. Ladenko

Abstract In this paper, we propose one of the ways to increase the octane number of gasolines using organically modified catalysts as contacts of the upgrading process. Materials and methods The sample Fe (silicate module 35, Fe3+ 0.2%; sample FeMn (silicate module 35, 0.2% Fe3+ and Mn2+) Results In the course of the research it was found that additional modification of the initial samples of organically modified zeolite- containing catalysts with iron and manganese reduces the rate of coke formation during the refinement of straight-run gasoline fractions. Conclusions The rate of coke formation increases with the increase in the silicate module of the zeolite. Iron applied to the catalyst in a small amount helps suppress the compaction and coking reactions, prolonging the eff e life of the organically modifi zeolite catalyst.

Problems and practical results of import substitution in the field of additives to fuels and lubricant oils

Alexander M. Danilov, Kirill A. Ovchinniko, Ruslan V. Bartko

The current state of additives to fuels and lubricant oils in Russia and possibility of providing producers of fuels and oils with domestic products is considered. The country completely provides itself with antioxidants and ignition improver for diesel fuels, with success carries out import substitution in the field of antiwear additives. A problem there is a development and the organization of production of the depressor dispersing additives and additives for production of fuels for jet engines. As for lubricant oils, manufacturers are capable to offer rather big range of additives. But the main objective consists not simply in replacement of an import product own, and in providing the producerof oils with perspective additives with the characteristics corresponding to international standard.

Cluster technology of preparation and injection of produced water into the reservoir using a pipe phase divider

Alexander V. Lekomtsev, Pavel Yu. Ilyushin, David A. Shishki

The main parameter of the quality of the injected reservoir water, which has an impact on reducing injectivity of injection wells, is the concentration (content) of oil and solidparticles (SP). In conditions of high load of well production preparation objects is not always possible to achieve these requirements. On Majachnye field of workshop oil and gas 5 there are certain problems. In addition, in the field there are well clusters, producing high water cut products. It increases the economic costs of transportation and preparation ofoil emulsion. In this regard, the issues of improvement of produced water quality for injection, the reducing the load of in-field training facilities and the reduction of transportation costs and the destruction of oilemulsion becomes more urgent. This paper presents a solution - Cluster technology of preparation and injection of produced water from wells into the reservoir using a pipe phase divider.

Optimization of determination of level of aggrigating of asphalten in crude oil

Kanan I. Hasanzadeh, Rauf N. Abdulov

Depending on content of asphalten compounds in the crude oil the color of the latter changes beginning from the black as far as light yellow. For example, the Baku crude oil is featured by blue illumination and Grozny one by green light. The more content of asphalten in the crude oil the darker is latter. According tothe experimental researches the level of aggregation effects on spectral characteristics of crude oil. It is suggested that the variation of concentration of asphalten leads to changingof its agrigation condition which inevitably changes the spectral characteristics of crude oil. It is shown that the existed methodics for assessment of aggregation condition of crude oil doesnt contain the quantitative parameters for determination of accuracy of assessment depending of selected wave length of measurements. The new methodicsfor optimum assessment of accuracy of determination of aggregation condition of asphalten is suggested.

Elena A. Zelenskaya, Tatyana V. Zelenskaya

At present the development and improvement of processes deep oil refining requires a new approach to solving the current economicand environmental problems associated with large energy costs and environmental pollution. And recent advances in the chemistry of salt melts, usually formed by organic cations, which are known as ionic liquids can partially solve the problems indicated. The basis of this work inspired the creation of new catalysts for refining toproduce high-octane hydrocarbon fractions. The proposed method allows to achieve a significant increase in the octane number ofengine fuels and, consequently, improving its performance, at low energy cost.
