In the era of digital technology, more and more of it finds application in various industries. This paper proposes to use technology of augmented reality for maintenance of stirred tank reactors. The proposed approach can be applied to any type of equipment, as it can be easily integrated with the existing automation systems and does not require much investment at the initial stage, implying gradual optimization and functionality build-up. This paper describes the basic set of functional requirements of an augmented reality-based maintenance system, methods of assessing the system performance, as well as scaling-up and streamlining prospects. The paper also describes how such systems can be integrated with existing control systems of a production company. The effectiveness of the developed augmented reality-based system was verified by determining the average execution time of each service stage and processing the outcomes using the Mann-Whitney U test. The use of the augmented reality system resulted in the reduction of the average service time by 2.3 times, while the maintenance efficiency increased by 5%.

The article presents an approach to determining the electric drive’s operability based on an asynchronous motor with a short-circuited rotor and a two-link frequency converter. Mathematical description of the frequency-controlled electric drive is performed, in particular, selection of criteria taking into account an electric and mechanical part. The harmonic current distortion coefficient as a component of the power coefficient is used for the determination of the energy criterion. The mechanical criterion is the coefficient of the electromagnetic moment pulsation, on the value of which the conjugated equipment depends. The operability field is represented as a function of three variables: (а) rotor speed, (b) current harmonic distortion coefficient, and (c) electromagnetic moment pulsation coefficient. The obtained surface makes it possible to determine the actual state of the electric drive and to estimate the reserve of operability, which allows reducing the operating costs in terms of repair and maintenance.

Present article is dedicated to the analysis of problems of the oil industry of Russia and is aimed at the development of a mechanism for its growth. The research is based on the results of the economic analysis that has been carried out on the basis of statistical data from the government and major oil companies as well as on the basis of analytical reports of independent companies. Among the main identified problems of the oil refining industry it can be mentioned following problems: insufficient volumes of raw material processing, lack of refinery capacities, remote location of oil extraction and refinery plants from the end users and unbalanced tax system in the industry. Specified problems are being solved on the level of companies and the state that brings results, however, there is no clear development mechanism of the oil refining industry so far. The authors suggest a development scheme for the Russian oil refining industry implying cooperation of businesses and the state. The implementation of the proposed scheme will ensure the investments for the extension of production and obtaining a product with a higher added value as well as increasing the competitiveness of the Russian oil products.
