Analytical Modeling of Current and Potential Distribution over Carbon and Low-Consumable Anodes during Aluminum Reduction Process

Andrey A. Polyakov et al.

Summary: Based on existing analytical models and the theory of current and potential distribution, the tertiary current and potential distributions over carbon and non-consumable anodes in cryolite-alumina melt are calculated. The relationship between electrolysis parameters, anode surface geometry, and current and potential distribution is established, and the influence of distribution pattern on anode process stability and anode consumption is discussed. The findings suggest that anode overpotential and diffusion layer thickness are the main factors affecting current and potential distribution, and the uneven distribution across the anode surface can lead to increased anode consumption and destabilization of electrolysis. Possible methods to equalize the distribution are presented.

Technique for calculating technological parameters of non-Newtonian liquids injection into oil well during workover

Dmitry V. Mardashov et al.

Summary: This article presents a technique for automatically calculating technological parameters for injecting non-Newtonian liquids into a well during workover. The algorithm processes initial flow or viscosity curve to determine rheological parameters and coefficients for non-Newtonian fluids. Based on the calculations, decisions can be made on changing the technological parameters or composition of the injected liquid to prevent violations of the operation and hydraulic fracturing, which can lead to catastrophic absorptions and uncontrolled gas breakthrough.

Justification of a comprehensive technology for preventing the formation of asphalt-resin-paraffin deposits during the production of highly paraffinic oil by electric submersible pumps from multiformation deposits

Mikhail K. Rogachev et al.

Summary: Production of highly solidifying abnormal oils in the Far North is hindered by the formation of asphalt-resin-paraffin deposits. Existing methods do not fully prevent the formation of these deposits, leading to decreased oil production and increased operating expenses. A new integrated technology shows promise in improving operational efficiency and reducing organic deposits formation in the tubing string.

Indicators and regularities of hydrolytic decomposition of metastable aluminate solutions in the Na2O-K2O-Al2O3-H2O system

V. N. Brichkin et al.

Summary: There is a renewed interest in potassium-containing raw materials due to the gradual depletion of reserves and the high demand for products such as potassium fertilizers and aluminum-based materials. The study found a special point in the degree of hydrolytic decomposition of aluminate solutions at a mole fraction of K2O equal to 0.33, suggesting a change in the process mechanism. The correlation between the degree of decomposition and the particle diameter of aluminum hydroxide precipitate indicates a close relationship between growth processes and hydrolytic decomposition mechanisms in aluminate solutions.

Summary: Parties to the 2015 Paris Agreement have pledged to limit global warming to below 2 degrees Celsius, but a sharp decline in fossil fuel use is required to keep the temperature increase below 1.5 degrees Celsius. A global energy systems model shows that by 2050, 60% of oil and fossil methane gas, and 90% of coal must remain unextracted to stay within a 1.5 degrees Celsius carbon budget.
