Digital transformation in refinery
Keywords: digital transformation, digital maturity, big data, cloud technologies, industrial Internet of things, predictive analytics, machine learning, virtual and mixed reality, connected industrial process, connected equipment, connected personnel.
The paper discusses the readiness of oil processing industry to global digital transformation (DT) that have engulfed the modern economy. The digital maturity of refinery is evaluated in comparison with other business sectors, and the reasons for the relative lag of oil refining in the production DT are examined. The article analyzes the actual DT content and the main benefits from the introduction of digital technologies in the refinery business processes, including reliable and optimal process control, monitoring and predictive maintenance of equipment, and ensuring safe and effective work of personnel. The breakthrough digital technologies that provide DT in oil processing – Industrial Internet of Things, cloud computing, data analysis, machine learning, supply chain optimization, etc. are described. An example of a holistic approach to DT in oil refining is given.

Effect of the design and technological parameters of a linear alkylbenzene sulfonation film reactor on the formation rate of by-products using the mathematical modeling method
Влияние конструкционных и технологических параметров пленочного реактора сульфирования линейного алкилбензола на скорость образования побочных продуктов с применением метода математического моделирования
Keywords: sulfonation, linear alkylbenzene, alkylbenzenesulfonic acid, multi-tube film reactor, tetralines, sulfones, mathematical modeling.
In this paper we analyze the influence of the structural parameters of a multi-tubular film reactor for linear alkylbenzene sulfonation (LAB) on the formation of such by-products as tetralins and sulfones applying the method of mathematical modeling. The content of tetralines and sulfones in the product mixture negatively affects process, because these substances form a highly viscous component that degrades the properties of the product. Moreover, highly viscous component accumulates on the inner surface of reaction tubes and other structural parts of the reactor. To eliminate these negative effects, the reactor is washed. To achieve greater economic efficiency of the process, as well as reduce environmental load it is necessary to achieve the maximum duration of the reactor operating period and the minimum number of reactor washes. As a result, the optimal design of the sulfonation reactor was determined. The most optimal reactor consists of 40 tubes with the diameter d = 43 mm. It is shown that with a change in the LAB flow rate in the reactor tube, an increase in the mass transfer coefficient occurs. So, at a LAB volume flow rate per tube V = 0.95 ∙ 10-5 m3 / s, the mass transfer coefficient is 1.73 ∙ 10-2, and at V = 2.86 ∙ 10-5 the coefficient is 2.08 ∙ 10-2.

Problems of regeneration of used oil oils
Проблемы регенерации отработанных нефтяных масел
Keywords: waste oil, regeneration, utilization, ecology, environment, hydrotreating.
The need to regenerate waste oils is due to continuously increasing environmental requirements and requirements for the use of renewable sources of raw materials. In the pre-war and post-war periods, government regulations were adopted to encourage the collection of waste oils. Regeneration plants were created at a number of refineries. During the period of perestroika, the system of centralized collection and regeneration of waste oils collapsed. Russia is one of the last countries in the world to collect and regenerate waste oils. The government has outlined a strategy for the development of the industry for recycling, neutralization of production waste, and regeneration of used oils. To implement the strategy, it is necessary to improve the regulatory framework and establish financial incentives for the collection and recovery of waste oils.
