The process of catalytic hydroprocessing of residual gas-condensate raw materials is one of the ways to improve the quality and expand the product assortment of the enterprise. Hydrocatalytic technology of refining high-sulphur fuel oil includes the process of heat treatment, when hydrogen is acting as a reagent under high pressure in the presence of catalysts, which reduces the concentration of impurities (metals, sulphur and nitrogen compounds) in the product. The article offers and substantiates operation principles of catalytic hydrogenation of fuel oil in the Astrakhan gas processing plant, and main technological parameters of the process. There has been carried out the preliminary economic assessment the qualified processing 500 t/year of fuel oil. To develop the technology for qualified fuel oil processing there has been created an experimental setup, which is operating under high pressure. The scope of major parameters of experimental research has been defined. Astrakhan fuel oil refining using hydrogenation catalytic process allows to obtain the high quality oil product with sulphur content less than 1% of mass. Using the hydrogenate is feasible as a marine fuel component, because it helps to decrease environmental burden from combustion product emissions.

The article presents the results of large-scale laboratory tests carried out in the conditions of the Chemical and Metallurgical Institute named after V.I. Zh. Abishev on the use of briquetted mono-charge in the smelting of carbon ferrochrome on a 250 kVA furnace. The purpose of these studies was to determine the technological parameters of the use of briquetted mono-charge containing in its composition chrome ore, wastes from the production of high-carbon ferrochrome, middlings and various carbonaceous reducing agents. The main idea of using these briquettes was to multiply the contact surface of the reductant and ore, which should speed up the technological process. The principal possibility of smelting a standard alloy using briquetted mono-charge is shown. The alloy for individual charge options meets the requirements of the standards. In comparison with the technology without the use of briquettes, the mono-charge technology has shown advantages in all main parameters. The technology with the use of briquettes from the dust of the AktZF gas cleaning system is distinguished by a low yield of non-standard metal and slag, the bulk of the material goes into the gas collection system. Technologies from briquettes from fines pellet production area of Donskoy ore mining and processing plant and flash have very low specific technical and economic indicators and cannot be recommended for industrial use. Improvement of briquetting modes and technology of their smelting is required. The technical and economic indicators were higher than the current one, showed briquettes from ore and coke of the People's Republic of China, briquettes of ore from borlin and shubarkol coals of Kazakhstan.

Maritime transport is a significant contributor to the environmental pollution. For this reason, the maximum sulfur content in liquid marine fuels has been drastically reduced since January 1st 2020 for deep sea areas. This reduction can be solved by diluting the conventional high sulfur fuels with suitable low sulfur components. However, mixing two or more components with each other carries a potential risk of incompatibility or instability of the final product, especially in the case of longer storage and subsequent transportation to the end consumers. For the above reasons, this work deals with the mapping of alternative raw materials that could be used to produce very low sulfur fuel oils (VLSFO) with a sulfur level up to 0.5 wt%. A total of 5 raw materials (1 conventional fuel oil – HSFO and 4 alternative raw materials) were characterized. The individual raw materials were compared to each other with regard to the quality properties required for marine fuels according to the ISO 8217. Subsequently, the suitability of these raw materials for further mixing was outlined in order to meet the required quality parameters for marine fuel mixing.

Low-viscosity marine fuel oil that is obtained from the products of residual raw materials and middle distillate fractions of oil is intended for use in ship engines instead of a diesel fuel. A real-world application of this new composition is of great importance A proposed new composition of low-viscosity marine fuel oil is created by compounding a mixture of oil distillates in accordance with the following parameters. The oil distillate mixture should contain a vacuum distillate fraction 420-490°C, a vacuum distillate fraction 350-420°C and a straight-run diesel fraction 180-350°C taken in certain ratios. This study presents the new fuel composition and its technical advantages over previous analogues. The benefits include improvements in the coking properties and storage stability due to the stability in the pour point indicator.

The content of hydrogen sulfide in the gas condensate of the Astrakhan gas condensate field, which is the raw material of the Astrakhan gas processing plant (Astrakhan GPP), is about 26% by volume. The high content of sulfur compounds in the reservoir mixture leads to an increased content in the fraction of >350°C, which is obtained during the primary fractionation of stable condensate. The selection of an effective reagent for the absorption of hydrogen sulfide and mercaptans from fuel oil is a very urgent task that is important for the company’s economy. The results of laboratory tests of reagents-neutralizers are the first stage of admission to industrial use at the Astrakhan GPP. This article is devoted to the search for analogs of reagents-neutralizers for reducing hydrogen sulfide and mercaptans in the fuel oil of the Astrakhan GPP.

At production of stainless steel expensive alloying elements, containing nickel, are used. To decrease the steel cost, substitution of nickel during steel alloying process by its oxides is an actual task. Results of analysis of thermodynamic and experimental studies of nickel reducing from its oxide presented, as well as methods of nickel oxide obtaining at manganese bearing complex raw materials enrichment and practice of its application during steel alloying. Technology of comprehensive processing of complex manganese-containing raw materials considered, including leaching and selective extraction out of the solution valuable components: manganese, nickel, iron, cobalt and copper. Based on theoretical and experiment studies, a possibility of substitution of metal nickel by concentrates, obtained as a result of hydrometallurgical enrichment, was confirmed. Optimal technological parameters, ensuring high degree of nickel recovery out of the initial raw materials were determined. It was established, that for direct steel alloying it is reasonable to add into the charge pellets, consisting of nickel concentrate and coke fines, that enables to reach the through nickel recovery at a level of 90%. The proposed method of alloying steel by nickel gives a possibility to decrease considerably steel cost at the expense of application of nickel concentrate, obtained out of tails of hydrometallurgical enrichment of manganese-bearing raw materials, which is much cheaper comparing with the metal nickel.

It is known that development of gas, gas-condensate and oil deposits is related with production of associated mineralized water. For creation of highly profitable processes of production and processing of hydrocarbons the methods of utilization of secondary sources of raw materials and energy become very important. The volumes of produced associated water at the petroleum complex facilities are so great, that it permits to consider them as a source of raw materials for processing with further receiving various commodity products, for example, process liquids, drilling fluids, iodine, bromine and their compounds.
