A technology for catalytic hydroprocessing of oil residues – atmospheric residue and vacuum residue – aimed to obtain high value added petrochemicals, particularly marine fuel complying with modern technical and environmental requirements, is reported. The technologyis based on the use of catalysts supported on alumina with a hierarchical structure of meso- and macropores, which are highly active and stable under severe conditions of the process. Data obtained by physicochemical analysis of the chemical composition, textural and phase properties of fresh and spent catalysts for the three-step hydroprocessing of atmospheric residue and vacuum residue are presented. A material balance for each step of the processes and a comprehensive analysis of the properties of produced petrochemicals were used to propose variants of implementing and integrating the technology at Russian oil refineries in order to increase the profit from oil refining. The introduction of the hydroprocessing of atmospheric residue at oil refineries without secondary processes will improve the economic efficiency due to selling the atmospheric residue by 84–170 % depending on a chosen scheme of the process and a required set of products. It is reasonable to integrate the catalytic hydroprocessing of vacuum residue with the delayed coking, catalytic cracking and hydrocracking processes in order to increase the depth of refining to 95 % and extend the production of marketable oil refining products: gasoline, diesel fuel, marine fuel with the sulfur content below 0.5 %, and low-sulfur refinery coke for the electrode industry. The integration of the hydroprocessing of vacuum residue with the secondary processes will increase the economic efficiency from selling the vacuum residue by a factor of 2–2.5 in comparison with its production in delayed coking units.

In recent years, there has been a trend in the global oil industry to improve the proportion of heavy high-sulfur crude oils in the total volume of extracted and processed resources, reserves of which are estimated at over 800 billion metric tons. Therefore, the main line of oil refining is processing of heavy crudes and residua to allow maximum use of the hydrocarbon potential and yield of high-margin products. Hydrogenation processes of heavy raw materials are most attractive in terms of product quality. This article analyzes tar hydrocracking processes that are either in operation or at the stage of full-scale testing. These include Veba Combi-Cracker (VCC), Uniflex, suspended-bed catalyst hydrocracking (ENI), and vacuum residue hydroconversion (TIPS RAS). These technologies use heterogeneous catalysts and are designed to obtain the largest possible amount of liquid products. This article discusses the features of each technology, highlights their advantages and disadvantages, shows the main approaches to process management, and speculates about the development of these technologies. Tar refining is a major process in heavy oil upgrading, and the development of efficient tar-processing methods will influence refinery configurations and management.

The oil refining industry in Iraq is one of the industries of strategic importance, and what these industries have been subjected to destruction, obsolescence and neglect in a way that led to the deterioration of oil products in quantity and quality, and in a manner that is not commensurate with Iraq's capabilities in the field of daily crude oil production, as well as its incompatibility with laws and standards. In addition to the inability of these industries to achieve self-sufficiency and resort to closing the gap through imports. The study assumes that rebuilding the oil refineries in Iraq on modern foundations commensurate with international environmental laws and standards, will contribute to achieving self-sufficiency in high-quality oil products and open new horizons for the refining industry. The study reached several conclusions, the most important of which are the most important reasons for the decline in the production of refineries in Iraq, failure to implement investment projects for the oil refineries sector, reliance on old methods of liquidation, obsolescence of treatment units, neglect of maintenance and maintenance operations, and continuous stops due to the interruption of electrical current, and sabotage of some pipelines that transport crude oil to the refineries. The researcher recommended that the existence of a strong sector of refineries in Iraq capable of securing energy sources and achieving self-sufficiency, in addition to its ability to compete, that achieving this goal requires working on building new and modern refineries and rehabilitating old refineries to increase production capacities and obtain high-quality oil products to Iraq can compete in the global

Coke producers often face a shortage of valuable grades of coals, i.e. coking coals. This paper examines the possibility to obtain a coking additive by applying delayed coking to various types of heavy petroleum residues. The paper also gives a comparative description. Five types of heavy petroleum residue from the KINEF oil refinery were used in the experiments that aimed to produce carbon material. They included vacuum residue ELOU-AVT-6, vacuum residue S-1000 resultant from the hydrocracking process, visbreaker bottoms from the S-3000 unit, and two mixtures of the ELOU-AVT-6 unit products: a mixture of vacuum residue and third vacuum cut; and a mixture of vacuum residue, third vacuum cut and atmospheric residue. The carbon material obtained from all the above types of raw materials was analyzed for quality; an X-ray diffraction analysis was carried out; and the interplanar spacings d002 and d110 were calculated, as well as the linear sizes of Lc and La crystallites. The coking additive obtained instead of the typical petroleum coke was found to meet the specification. Thus, the volatile matter content in it is within the range from 15 to 25 wt%. This additive can be used in steel production instead of coking coal. The coking additive from a mixture of vacuum residue, third vacuum cut and atmospheric residue has the highest content of volatile matter (19.30%), while the coking additive from the visbreaking residue from the S-3000 has the lowest volatile matter content (16.15%). The latter is due to the fact that the primary petroleum material was subjected to light thermal cracking. It is shown that as the composition of the heavy petroleum residue changes, so do the properties of the resultant coking additive: a higher fraction of the low-boiling components in the feedstock is associated with a higher volatile matter content; the carbon materials produced from vacuum residue have a higher microhardness; the coking product produced from the visbreaker bottoms has a lower porosity compared with the product obtained from the vacuum residue. This research was carried out as part of a governmental assignment of the Ministry of Education and Science of the Russian Federation in the framework of the following research project: 0792-2020-0010 “Fundamentals of innovative processing techniques to obtain environmentally-friendly motor fuels and innovative carbon materials with variable macro- and microstructure of the mesophase from heavy hydrocarbon materials”. The research was carried out at the laboratory of the Shared Knowledge Centre of the Saint Petersburg Mining University.

This paper analyzes structural indicators of economic efficiency and energy intensity consumption as determinants of sustainable economic development for the selected 33 European countries. The correlation, regression and multivariate factor analyses are applied to test the associations between the selected structural variables of energy intensity consumption, economic efficiency, and the main driving forces behind these developments. Economic efficiency is positively associated with expenditures on research and development (R&D) and a greater technological intensity of exports, while at the same time the economic efficiency of R&D expenditures and technological intensity of exports reduce the energy intensity consumption of the economy. The results suggest that management strategies and policies directed towards R&D expenditures, human capital investments, and technologically intensive export oriented products are improving economic efficiency performance and contributing to energy saving sustainable economic development. The technological intensity of products reduces energy consumption, which is related to restructuring of energy intensive industries into more advanced and energy saving ones with higher value added per unit of product, but with lower energy consumption per unit of product.

AbstractBanana peel (BP) is an agrowaste produced in large volumes annually, especially by food-processing industries; however, its disposal is of significant concern. However, recent research suggests that BP is a valuable source of bioactive compounds, which can be converted into value-added products. This article reviews the conversion process of value-added products from BP and provides an outline on the chemical composition of BP and its possible applications. In addition, we also discuss the utilization of BP as a substrate to produce animal feed, biofertilizer, dietary fibers, clean energy, industrial enzymes, as well as its use in the synthesis of nanomaterials. Based on the research conducted so far, it is obvious that BP has a wide variety of applications, and thus, developing a biorefinery approach to adequately utilize BP will help realize its economic benefits to the fullest. Based on the valorization of BP, a scheme for BP biorefinery has been proposed. A material balance for BP biorefinery for 1-ton bone-dry BP is presented and our results show that 432 kg of protein or 170 kg of citric acid, 170 kg of pectin, 325 m

Today, one of the most widespread processes in modern oil refining is the production and purification of hydrogen, which is used in the production of ammonia, methanol, and plastics. Without it, the production of high-quality motor fuels is impossible, since this gas is involved in the hydrogenation process (hydrotreating) [1]. Currently, at oil refineries and petrochemical plants, hydrogen is obtained in two ways: from natural gas by steam reforming into a mixture of hydrogen and carbon monoxide (synthesis gas), in a catalytic reforming unit, where a mixture of hydrogen and light hydrocarbon gases (hydrogen-containing gas) is released. Most modern oil refineries have a hydrogen production unit, its widespread use in industry is explained by its chemical activity, ease of production and high exothermicity of the process [2].

Inability to fulfill the demand of consumers is becoming the major issues on citronella oil refinery in the village of Cimungkal Sumedang. This study was conducted to formulate alternative measures in order to increase the production of citronella oil distillates in the Cimungkal village. Mapping of the production process is done with Value Stream Mapping (VSM) as a first step to determine the processing time (lead time of production) and identify the waste that occurs, analyze the causes of the problems at the manufacturing level, and formulate remedial measures to increase the production of oil of citronella. The results show some activity in the production process of citronella oil which is a waste and should be minimized. By mapping, it can be seen that the lead time citronella oil refining initial amounted to 647 minutes or 10.78 hours. After repairs (Future State) improvements Total lead time to 274 minutes. Value-added activity increased by 38.93%, non-value added decreased by 3.63%, and necessary but non-value added fell by 35.3%. The study also resulted in the formulation of strategies that can be done to increase the production of oil of citronella.
