“…Vogt [12,13] studied the gas-evolving phenomenon and found that it strengthens mass transfer. For thermoelectric coupling, some studies [14][15][16] found that current intensity and electrolyte height are important for the thermal balance in a cell, which considerably affects the electrolysis efficiency and production. In the aluminium reduction cell, Tessier et al [17] developed a multiblock partial least-squares modelling approach for multivariate analysis and monitoring of aluminium reduction smelters and other electrochemical processes, and Zhang et al [18] developed a microscale modelling approach for the investigation of bubble dynamics in the aluminium smelting process.…”

Based on an electrochemical multiphysical simulation, a method for analysing electrolysis efficiency has been presented that considers the energy consumption required to produce a single kilogram of lithium and for the production of lithium, rather than the voltage in various parts. By adopting them as the criteria for analysing electrolysis efficiency in the lithium cell, several structural parameters have been optimized, such as the anode radius and anode–cathode distance. These parameters strongly affect the cell voltage and the velocity field distribution, which has a significant impact on the concentration distribution. By integrating the concentration distribution, the lithium production and energy consumption per kilogram, lithium is computed. By appointing the minimum of the chlorine and lithium concentration as the secondary reaction intensity, it is clear where the secondary reaction intensity is strong in the cell. The structure of a lithium electrolysis cell has been optimized by applying an orthogonal design approach, with the energy consumption notably decreasing from 35.0 to 28.3 kWh (kg Li) −1 and the lithium production successfully increasing by 0.17 mol.

“…Therefore, computational uid dynamic (CFD) calculations provide an opportunity to quantify ow eld distribution values in MBRs that cannot be detected experimentally. [8][9][10][11] Consequently, numerical methods have been developed that enable ow rates in aerated membrane ltration processes to be predicted accurately. [12][13][14][15] Yang et al 16 used CFD model for the cost-effective optimization of MBR and the model further revealed that the high nitrogen removal efficiency (>90%) was achieved due to the high recirculation ratio driven by airli force without destroying the oxygen deprivation and enrichment in the anoxic and oxic zone, respectively.…”

This review study analyses the existing methods for increasing the oxidation resistance of carbon-graphite products, as well as assesses their applicability in metallurgical and chemical units. The reseach basis was the data published on the oxidation mechanism of carbon-graphite materials, conditions for their use in metallurgical and chemical processes, as well as existing technologies aimed at improving the oxidation resistance of artificial graphites. The existing ideas about the kinetics of carbon graphite oxidation are described depending on temperature conditions. A review of existing technologies for increasing the oxidation resistance of materials and their economic efficiency, taking into account the conditions of their operation, was carried out. Prospects of the presented solutions for the units of metallurgical and chemical industries were analysed. Three modes of oxidation of graphitised materials were distinguished on the basis of operating conditions, chemical and physical properties. According to this classification, the most rational method for increasing oxidation resistance consists in the impregnation of carbon-graphite materials with the formation of a protective glassy coating in the volume of through pores or with the formation of a coating (a continuous layer on the surface of the product) due to the occurrence of a chemical reaction with the reagents used. For most metallurgical and chemical units, the impregnation of carbon-graphite materials with the formation of borate and phosphate glasses is preferable, primarily due to lower economic costs. The applicability of this method is currently limited by temperature conditions, at which the protective properties and continuity of the formed glassy coatings are preserved. Therefore, additional research is required to adapt the conventional technological and technical solutions to the high-temperature conditions of metallurgical units (over 800°C).
