Peculiarities of application of modern physico-chemical methods of laboratory investigation of oil bitumes and bitumen mixtures (in customs laboratories)

Lobachevsky State University (UNN)

Keywords: petroleum bitumen, bitumen mixture, polymer-bitumen road binders (PBRB).

Abstract Composite materials, including petroleum bitumen - bitumen mixtures, modified bitumen, are appearing more and more often on domestic and world markets. When speaking of "bitumen mixtures, modified bitumens," it should be understood that bitumen products of different composition and purpose fall under this definition.
Active expansion of Russia's foreign economic activity, as well as the status of the country as a country with a significant potential in the production of oil products, all contribute to a more active export from the country and import of petrochemical products into it. Export of oil bitumen and bitumen products takes a rather high line in a number of exported goods. At the same time, the difference in the rates of export duties on goods is a frequent cause of cases of inauthentic declaring of goods by dishonest sellers for "leaving" from payment of customs duties. This fact is due to the investigation of bitumen mixtures in customs laboratories. The task of determining polymeric modifiers in bitumen mixtures is especially urgent.
Petroleum bitumen, modified with a polymer, as an object of research, is of interest not only to employees of customs laboratories. The questions of the composition of such mixtures, the nature of the changes in their properties are interesting and are considered in many scientific works. Most of the scientific work is devoted to the study of physical (so-called "commercial" indicators) properties of bitumen products based on petroleum bitumen modified with a polymer. But the introduction of new technologies for processing petroleum raw materials and production of petroleum products, complicating the composition of polymer-bitumen compositions and expanding the range of such products makes it necessary and urgent to determine the quality and quantity composition of bitumen mixtures.
In this paper, we propose some practical algorithm for physical and chemical research that allows us to investigate as completely as possible the chemical composition of the bituminous product and its properties: determine the type and type of filler or modifier, evaluate the nature of the components of the mixture, their number and significance. It is assumed that the methodology of the integrated study of bituminous binders given in the algorithm will probably be used not only for solving tasks related to the activities of customs laboratories (identification) but also for research aimed at solving the problems of a scientific plan for determining the qualitative and quantitative composition of bitumen mixtures, their structure and composition.

Temperature performance parameters of motor oils

Koval'skiy B.I., Pustovit P.Yu., Batov N.S., Lysyanikova N.N.

Siberian Federal University Institute of Oil and Gas

Keywords: evaporability, optical density and coefficient of thermo-oxidative stability of motor oils, methods of monitoring the performance of motor oils.

Abstract A method is proposed to control the additional temperature parameters of the partially synthetic synthetic engine oil “Lukoil Super 10W-40 SG / CD”, including determining the temperatures of the onset of oxidation, evaporation and temperature transformations, the critical temperatures of these processes. It is shown that for comparing lubricants of a single purpose, it is necessary to take constant values of the test time and thermo-oxidative stability indicators expressing optical density, evaporation and thermal-oxidative stability coefficient. These studies are aimed at expanding information about the temperature parameters of the performance of lubricants. For the study selected all-season, universal partially synthetic engine oil “Lukoil Super 10W-40 SG / CD”. As the means of control and testing, the following were chosen: instruments for thermostating the oils, a photometric device and electronic scales. The research method was as follows. A sample of constant-weight oil 100g was poured into a glass beaker for temperature control and tested sequentially at three temperatures of 180, 170 and 160° C with stirring with a glass stirrer with a rotation speed of 300 rpm for a constant time of 8 hours. The resource of lubricating oils depends mainly on the temperature on the friction surface, which accelerates oxidation processes, temperature decomposition and chemical reactions of metals with oxidation products and additives. In this regard, it is important for designers and technologists to know the temperatures at which these processes begin and the critical temperatures at which abnormal phenomena occur. Therefore, the purpose of these studies is to test the method of control to determine these temperatures. On the basis of the conducted studies, it has been shown that the application of the proposed method for monitoring the temperature limits of the performance of motor oils provides additional information on the temperature regimes of their use and improves the classification system.

Specification of PJSC «Avtodizel» motor oils for transport diesel engines with high environmental performance

Boykov D.V., Bugay T.B., Petrov K.N.
PJSC «Avtodizel» Yaroslavl Motor Plant

Keywords: motor oils, diesel engine, ecological index.

The article provides information about the technical requirements of PJSC "Avtodizel" for motor oils for diesel transport engines of environmental classes 4, 5, 6.
Oil requirements determine the required level of physico-chemical and performance indicators of oils based on the results of laboratory and bench tests. Laboratory tests measure the number of traditional physico-chemical parameters which are included in passports of quality oils (base number, sulphated ash content, volatility, corrosion on the plates of lead and copper, the content of zinc and phosphorus, etc.).In addition, using the original laboratory methods, the temperature of the beginning of lacing is estimated; hydrolytic stability; the ability of oil to hold the soot in suspension finely-divided condition; thermal and mechanical degradation of the thickening additive, etc.
The in formativeness of laboratory methods and a certain relationship of some parameters with the aging processes of oils in engines and contamination of their parts by carbon deposits.
The features of the aging process of oils in diesel engines of different models of YaMZ are considered. The results of the effect of exhaust gas recirculation on the intake (EGR) to increase oil aging, contamination of parts are presented. It is shown that to the greatest extent the EGR increases the response of the neutralizing properties of the oil to a greater extent than the forcing of the engine by the average effective pressure. The list of indicators by which the level of operational properties of oils is estimated at bench tests in engines (wear of cylinders, piston rings, bearings of a crankshaft; polishing of cylinders; pollution by carbon deposits of the and piston groove; increase in an oil consumption on waste; stability of preservation of technical and economic parameters of operation of the engine after tests) is given.
During bench tests, physical and chemical analysis of samples of the working oil is carried out to determine the change in anti-wear, detergent, anti-corrosive properties of the oil, colloidal stability. The influence of filters-neutralizer for exhaust gases and particulate filters on the properties of the used oils is considered. For engines of ecological class 6 with filters-neutralizers of the closed type (DPF) oils on the Low SAPS technology with size of sulphate ash content no more than 1,0% are recommended; with the content of sulfur and phosphorus no more respectively 0,4and 0,08%.
Approximate compliance of the level of operational properties of oils for engines with various environmental parameters according to the specification is given PJSC "Avtodizel" (RD 37.319.034-17) known standards: STO AAI 003-05, GOST 17479.1-85 and the American petroleum Institute (API) oil classification.

Abstract Chemmotology, the science that considers the existing relationship between the operation of machines, design feature of machines and applied of fuels and lubricants. The main objective of the chemmotology is to ensure the reliability of equipment during operation by ensuring the quality of fuels and lubricants. The purpose of fuel and lubricants is carried out depending on the operating conditions and design characteristics of the equipment. The purpose of fuels and lubricants is determined by the level of their operating ability. An example of the purpose of fuel for use in the Volvo XC-90 D5 is shown. Compliance of quality indicators of fuels and lubricants to the established requirements, provides the necessary level of performance. During transportation and storage, oil products are exposed to various factors, which leads to a change in the level of their operational properties and affects the chemmotological reliability of the equipment. Ensuring the conditions of transportation and storage, in which the impact of negative factors will be minimized will ensure the safety of the quality of fuels and lubricants and chemmotological reliability of equipment. Ensuring the functionality of all elements of the chemmotology system "Technique - fuel - Operation" will ensure the safety of its operation – "Chemmotology safety". Identification of the influencing factors and formation on the basis of their analysis of timely or preventive influences, is an effective way to ensure the quality of oil products during transportation. For the solution of the task of evaluating changes in the quality of petroleum products during transportation and to identify necessary control actions can be constructed imitating model of system of pipeline transport of petroleum products.

Neplatinal catalysts for riforming process

Gancev A.V., Vakhitova A.S., Munirov T.A., Galiakhmetov R.V.

Ufa State Petroleum Technological University

Keywords: catalytic reforming, hydrocarbon composition, neplatinal catalysts.

Abstract Catalytic reforming is one of the significant processes for obtaining marketable gasoline. Depending on the system, type, purpose and application of the catalyst, the catalytic reforming process, as well as the yield and quality of the products vary widely. There is a wide variety of reforming catalysts, differing in shape, size and structure. Despite the use of highly effective promoters that have reduced the content of platinum and simultaneously improve the performance of the catalysts, none of the non-platinum reforming catalysts that would provide the same large yields of products with high octane numbers are still unknown. The high cost of platinum-containing catalysts determines the need to search for new catalysts that could compete in their properties with known ones. In the course of the study, the efficiency of various catalysts was analyzed during the process. the results of the study showed the possibility of using non-platinum catalysts under milder conditions, without compromising the selectivity of the dehydrogenation process characteristic of catalytic reforming.
One of the reasons for the loss of catalytic activity of the catalyst is the deposition of the carbonaceous material in the porous structure of the catalyst as a result of its use. Typically, the carbon content of the spent catalyst is in the range of 1% by weight. up to 20% by weight. Even a sufficiently small amount of carbon significantly reduces the activity of the catalyst. The activity of the catalyst decreases if the sulfur content in it exceeds 0.1%.
A further task is to study and investigate non-platinum catalysts in order to optimize the process of catalytic reforming.

Tb- and Pr-containing polyoxotungstates as catalysts in the epoxidation of styrene with hydrogen peroxide

Alimardanov Kh.M., Najafova M.A., GaribovN.I., Musayeva E.S.

Y.H.Mamedaliyev's Institute of Petrochemical Processes of the National Academy of Sciences of Azerbaijan

Keywords: ESR, ultra-fine structure, oxides of terbium and presidium, a stable radical, styrene, phenyloxirane

Abstract One of the promising directions in catalysis is the use of heteropolysation (HPS) as oxide precursors, which are complex inorganic compounds formed by Mo and W atoms in the ligand environment and heteroatoms serving as complexing agents.Currently, a wide application in the industry for the oxidation of olefins, production of epoxides, alcohols, acetals are heteropoly compounds (HPC) of various structural types and new formations with high catalytic activity, such as HPS, replaced by rare earth elements (REE). However, using various methods (inhibitors, EPR) it is shown that such catalytic systems play the role of radical initiators. The latter pass from the surface of the catalyst to the volume of the liquid phase, where the oxidation products are formed by a radical chain mechanism.The role of the surface of catalysts in liquid-phase oxidation of hydrocarbons is reduced mainly to the generation of radicals, initiators of the chain process occurring in the volume. In this regard, EPR, more than another method of research, helps to clarify the laws of the formation of intermediate forms (complexes, radicals) and the final products of the reaction. By EPR spectroscopy of the studied paramagnetic nature of polyoxo tungsten catalysts synthesized on the basis of dodeka ammonium, activated by oxides of terbium and presidium. In oxides of terbium and presidium the catalyst spectra there is an ultra-fine structure of the lines ESR. It is found that different EPR lines are observed in the EPR spectra depending on the ratio Tb4O7-x and Pr6О11-x and polyoxovolfram. It is shown that the increase in the content of (NH4)10W12O41 × H2O with respect to Tb4O7-x and Pr6О11-x leads to the formation of a stable radical (∆Hbsh=5 mTl, g=1.92). The synthesized catalytic system is used for the epoxidation of the dodecene by hydrogen peroxide in the presence of H2C2О4. The maximum yield of epoxy at a temperature of 70-80°C with a reaction time of 3-4 hours is 75-82% on the converted dodecene.

Structural-group composition of the raffinate obtained by selective purification of the oil fraction, extracted from the oil of balakhany oil field

Keywords:hydraulic fluid, distillate extraction cleaning, raffinate, ionic liquid, hydrocarbon composition

Abstract In the presented article, the results of the research using the IR and NMR spectral methods of the structure composition of the base product of AMQ-10 named hydraulic fluid, which was obtained from Balakhani oil fraction (BP range 234-306°C) by selective treatment using N-methylpyrrolidonacetate based ionic liquid, were given.The distillate used in the research is characterized by the following characteristics: density at 850 kg/m3 at 20°C, kinematic viscosity at 2.3 mm/s at 50°C, ignition temperature - 110°C, freezing temperature - minus 75°C and aromatic hydrocarbons - 14% mass.
For comparison, the hydrocarbon group composition of the raffinate extracted from the selective treatment of the oil fraction by organic soluble N-methylpyrrolidone which mentioned in the article and acid contact method were also investigated by IR and UB spectral analysis methods.
It has been determined that absorption strips reflecting rate of the C-H bond in the aromatic ring (1604 cm-1) and the C-H bond in the CH2 (968cm-1) of hybrid naphthenic aromatic hydrocarbons is reduced in the samples taken from the extracted oil fraction. This has also been confirmed by the calculated values of the optical density of the absorbed strips. Thus, in raffinate extracted from selective treatment, the absorption strips in the 1031 cm-1 area was observed like feedstock. In additionally, the absorption strips rate of naphtha fragment and benzene ring decreased from 0.009 to 0.007 in the 968 cm-1 and 1604 cm-1 area respectively, which indicated that aromatic and naphthenic aromatic hydrocarbons was removed by selective treatment process.
UF spectral analysis of the raffinate samples which taken from selective treatment, demonstrates that the amount of the aromatic hydrocarbon decrease from 14.4% to 0.64-0.95%. In other words, the use of the ionic liquid composition as a selective solvent is more prospective.
Finally, according to the results of UB spectral analysis of the raffinate, the aromatic hydrocarbon weight amount is 2.56% (extracted from Balakhani oil fractions by using organic solvent N-methylpyrrolidone) and 2.5% (obtained by acidic contact treatment method). In addition, ionic liquid extraction is relatively predictive because of the ionic liquid composition is ecologically harmless and also useful as an extractant after regeneration process.

Vertical steel oil and oil products tanks spiral dismantling method application in terms of hazardous objects revamping

Применение метода спирального понижения при организации работ по сносу и демонтажу стальных вертикальных резервуаров нефти и нефтепродуктов в рамках реконструкции опасного производственного объекта

Keywords: innovation, modern building methods, removal petroleum reservoir, modernization of refineries.

Hazardous plants vertical steel tanks dismantling procedures peculiarities are reviewed. Works basic complex factors are classified, i.e. stage tanks replacement at the tank farm, tanks group single embankment, rack of tanks surface poor quality, emergency cases high probability during dismantling procedure. Vertical steel tanks dismantling ordinary methods are reviewed. During hazardous plants revamping vertical steel tanks dismantling is usually carried out by two methods: element-by-element from top to bottom dismantling and spiral disassembly.
Up-to-date tanks spiral disassembly is revealed in detail. The essence of the method is as follows: tank bottom is separated from tank wall by plasma-arc cutting, and then the wall is cut in a spiral direction from the bottom to the top; separated wall stripe is gradually removed by the force of gravity.
Vertical steel tanks dismantling methods comparative analysis is reviewed. Vertical steel tanks dismantling method is determined by complex factors, taking into consideration every particular case.
In fact, the choice of the dismantling method in some cases is determined by economic factors, rather than safety rules and regulations. The modern approach of the refinery's operational services implies dismantling procedures operating contractor responsibilities in case of emergencies or accidents.
It is worth mentioning, up-to-date and prospective methods of dismantling procedures in the civil industry introduction is inextricably linked not only with the improvement of normative and technical documentation, but also with the economic efficiency. At present, the capital expenditures are estimated in accordance with the estimate documentation that regulate all contractor payment transactions for the completed works. Construction industry situation, when estimate rates base is lagging behind civil processes, is not unique, and it interferes with adequate construction works estimation basing on the unified payment system.
Thus, at present it is necessary to ensure state policy to achieve successful up-to-date dismantling methods introduction not only in terms of innovative dismantling methods, typical flow charts and reference books creation but as well in terms of the intrinsic interface of construction methods and estimate rates base.

Substantiation of requirements to accuracy of flowmeters-regulators of control systems of synthesis gas production complexes

Обоснование требований к точности расходомеров-регуляторов систем управления комплексами получения синтез-газа

Keywords: synthesis gas generator, combustion chamber, partial oxidation, hydrocarbon gases, hydrogen, carbon monoxide, carbon dioxide, thermodynamic calculations, static characteristics.

Gas generators of synthesis gas (GSG), which are the main elements of synthesis gas (SG) production complexes and implement the technology of non-catalytic partial oxidation of hydrocarbon raw materials, mainly hydrocarbon gases (HCG) with various types by oxidizers-air enriched with air, oxygen are considered.
Control of technological processes in the complexes of SG production is carried out with the help of automated control and control systems (ACCS), which include local tracking systems that provide an automated output of GSG in the nominal technological mode and automatic stabilization of the nominal mode parameters during the normal operation of the complex. Flowmeters – mass flow regulators (MFR) which are the precision tracking systems and which are the most expensive elements of ACCS are used as the executive elements of these systems.
The composition and parameters of the SG used for further catalytic synthesis of the target products depend on the determining degree on the accuracy of reproduction of the nominal mode partial oxidation. Therefore, the actual task considered in the article is the development of methods for selecting the accuracy class of MFR.
On the example of partial oxidation of natural gas by air, the features of producing SG for low-tonnage methanol production are considered. The requirements for permissible static errors of reproduction of the nominal technological mode of partial oxidation are substantiated. It is shown that the maximum permissible errors of the natural gas and air supply to the GSG and the determination of their accuracy class are calculated on the basis of the requirements for the permissible errors of the excess oxidant coefficient. The choice of accuracy class of MFR of the supply of chemical treated water to the evaporating chamber of GSG is calculated on the basis of the requirements to the permissible error of the gas temperature control at the outlet of GSG.
The offered technique of a choice of accuracy class MFR allows you to secure precise control of the process of generating synthesis gas and to optimize the ratio price-quality while making package bundle ACCS complexes for producing synthesis gas.

Influence of oxidation processes of motor oils on their viscosity-temperature characteristics

Влияние процессов окисления моторных масел на их вязкостно-температурные характеристики

Keywords: optical density, viscosity-temperature characteristic, viscosity index, criterion of thermal-oxidative stability.

The results of the study of the thermooxidative stability of motor oils, taking into account the viscosity-temperature characteristics and optical density, are presented using such priors as a thermostatic instrument, a photometer and electronic scales. A criterion for thermal-oxidative stability is proposed, which is determined by the product of the optical density and the decimal logarithm of the viscosity index. The linear dependence of the proposed criterion for optical density is established. Based on these data, it is proposed to classify oils. A comparative characteristic of temperatures among the oils with the same class of operational properties is given. When choosing oils, the viscosity grade and base oil are taken into account. But there are no temperature indicators at which lubricants are most effective, and at which oil oxidation is optimal, ensuring maximum resource. To increase information on the temperature limits of the performance of lubricants for various purposes by applying their stepwise temperature control and photometric measurement. According to the proposed methodology, studies were carried out that showed a discrepancy between the temperature indices of the processes and the group of operational properties. On the basis of the conducted studies, it was shown that with the same classes of operating properties, temperatures of oxidation processes, evaporation and temperature transformations, they differ greatly, therefore, choosing an oil for a certain temperature mode of the engine, it is impossible to be guided only by the class of operating properties. It is also proposed to improve the existing classification system for oils.

Some peculiarities of the reaction of aminomethylation of sterically hindered cycloalkylphenols aminoethylnonylimidazoline

Некоторые особенности реакции аминометилирования пространственно-затруднённых циклоалкилфенолов аминоэтилнонилимидазолином

Keywords: phenol, methylcycloalkene, aluminum phenolate, sterically hindered phenols, aminoethylnonylimidazoline, formaldehyde, Mannich bases.

The results of cycloalkylation of phenol with diprene, dipentene and their mixture in the presence of an aluminum phenolate catalyst and the influence of various parameters on the yield of the desired product are presented. In order to find the optimal conditions ensuring the greatest yield of the desired product, the reaction temperature varied from 260 to 320°C, the reaction time from 3 to 9 hours, the molar ratio of phenol to cyclone from 1: 1 to 1: 3, the amount of the catalyst from 10 to 25%. It was found that the following conditions are necessary for obtaining the maximum yield of 2,6-di-[3 (4)-methylcyclohexene-3-yl-isopropyl]-phenols: temperature 300–350°C, reaction time 7-8 hours, ratio of phenol to methylcycloalkene 1: 2 mol / mol and the amount of the catalyst is 20-25% based on the phenol taken. In this case, the yield of the desired products of 2,6-di-[3 (4)-methylcyclo]-phenols is 40.4–43.3% of the phenol taken. Chromatographic studies of the products of cycloalkylation of phenol with isoprene cyclodimers in the presence of an aluminum phenolate catalyst showed that 2,6-dicycloalkyl-substituted phenols (68.5–77.7%) are mainly contained in the alkylate. After rectification of the alkylate at low pressure (20 mm Hg), the desired products were obtained with a purity of 92.4–94.0%, their physicochemical characteristics were determined. The 2,6-di-[3 (4) -methylcyclohexene-3-yl-isopropyl]-phenols obtained were subjected to aminomethylation with formaldehyde and aminoethylnonylimidazoline in a ratio of 1:2:2.
Interaction of 2,6-di-[3(4)-methylcyclohexene-3-yl-isopropyl]-phenols with formaldehyde and aminoethylinonyl imidazoline yielded Mannich bases with a yield of 61.3-69.8% of the theory. Physicochemical parameters of synthesized 4-hydroxy-3,5-di-[3 (4)-methylcyclohexene-3-yl-isopropyl]-benzyl-aminoethylnonyl-imidazolines were determined.
