How to certify reference materials: by voting or by exact weights
Как аттестовать стандартные образцы состава: по точным навескам или большинством голосов?
Keywords: oil, oil products, reference materials.
Abstract. The problems of using reference materials (RM) of oil and petroleum products humidity
is discussed for different programs of certification: according to accuracy of the preparation procedure
(RM-PP), according to the results of the interlaboratory studies (RM-INTERLAB) and using reference methods (RM-RM). Similar NIST samples (SRM 2271 and 272) were used for comparison. The problem of using CO-INTERLAB for control the accuracy of standard methods is the absence of the true value, this task is not even raised. «Accuracy control» has a different emphasis in this situation: RM-INTERLAB allow to select, «voting by majority» among the general population of the laboratory and cut the others.
Therefore, their main application is qualification tasks. This approach is basically incorrect for analyzers. In the case of RM-PP and RM-RM, the main problem is the difference in the composition of real samples and ideal matrices of RM’s. Their main application is the control the accuracy of the analyzers in the absence of interfering influences. The «cheap» RM’s production technologies do not allow the omprehensive control of the real oil samples. The complication of oil technologies and the use of heavy oils in refining could provide the progress in RM’s.

Effect of reaction time on the process of upgrading heavy oils in the presence and in the absence of oil soluble catalysts at 250 ° C.
Влияние продолжительности теплового воздействия на процесс облагораживания тяжелых нефтей c использованием нефтерастворимого катализатора при 250 °С.
Keywords: heavy oil, oil-soluble catalyst, SARA analysis, viscosity.
Abstract. This work presents the possibility of improving the quality of heavy oil during in-situ upgrading using oil-soluble catalysts based on copper (copper oleate) at 250 ° C under high pressure for 12, 24, 48 and 72 hours using a 300 ml stainless steel batch reactor. Different technique analyzes for heavy oil befor and after upgrading were carried out: Analysis of the evolved gas components by gas chromatography, determination of the group composition of oil (SARA analysis), measurement of viscosity, gas chromatographic analysis of saturated hydrocarbons. The results showed that with an increase in the time of experiments and the use of oil-soluble catalysts, the content of saturated fractions increases due to a decrease in the content of resins and asphaltenes, which leads to a decrease in viscosity of heavy oil from 2073.7 to 1290.5 mPa.s. According to the obtained results, it can be said that reaction time and the use of an oil-soluble catalyst increase the efficiency of the in-situ upgrading.

Digital monitoring system of equipment for the analysis of fuel and lubricants quality
Keywords: digital monitoring system; lubricants; quality; performance; defects; monitoring, equipment.
Currently, to increase the efficiency of industrial production, high-performance and expensive technological equipment is increasingly used, in which the weakest link, from the point of view of efficiency and reliability, is the components and parts of heavily loaded tribo – couplings operating both at significantly different temperatures (conditionally under lighter conditions, the temperature difference can be 100-120 degrees) and climatic conditions (high humidity, the presence of abrasives and other chemical elements in the atmosphere). As the results of the analysis of the frequency of failures of friction units and, accordingly, the cost of their restoration reach 9-20 percent of the cost of all equipment, without taking into account significant losses of income (profit) of the enterprise from downtime. The solution of this problem is based on the study of the wear rate of friction units by the wear products accumulated in working oils, cooling lubricants, and greases. A digital equipment monitoring system (DSMT) has been developed and implemented, which includes dynamic recording of the number of wear products and oil temperature by original modern recording devices, followed by the technology of their processing and use. The system also includes methods for finding the necessary information in large data sets useful and necessary in theoretical and practical terms with a similar technique controlled by a digital monitoring system. The advantages of SMT are the ability to predict the reliability of the equipment; reduce production risks and significantly reduce inefficient costs.
