This study is devoted to improving the economic efficiency of the cell, due to the field of the generated electromagnetic field’s accurate diagnostics. To solve this problem, the authors had developed a hardware-software complex for electromagnetic field diagnostics. This complex includes a measurement device and a software package for data collection and analysis. On the laboratory prototype of the aluminum electrolysis complex, a study was carried out on the formation and structure of the electromagnetic field. A number of experiments have been carried out showing the degree of formation of the electromagnetic field by the anode, the relationship of electromagnetic fields in the inter-anode space has been shown. Based on the results of the studies, conclusions were drawn about the possibility of diagnosing the current state of the anode, determining the direction of rotation of aluminum in the electrolytic cell and estimating the life of the anode and its burnout time.

“…According to the statistics, the volume of world's sulfur consumption amounts to about 65-85 million tons per year. Almost all of the obtainable sulfur is used to manufacture sulfuric acid, which, in turn, is an important resource in the production of phosphate and complex fertilizers [4].…”

“…Lack of sulfur in the human body can cause hair loss, as well as brittleness of the nails and bones [3]. However, sulfur compounds are considered toxic and have a negative impact on the environment, being one of the most dangerous pollutants in the world [4]. More than 96% of sulfur enters the atmosphere in the form of SO 2 , the remaining 4% is divided between sulfates, H 2 S, CS 2 , COS and other compounds.…”

Nowadays, sulfur is considered one of the primary resources of the chemical industry, most of which is produced as a refinery by-product during the processing of oil and natural gas. Sulfur production volumes are increasing every year, while the demand for it does not always match the growing supply, which leads to a serious problem of sulfur surplus in the world market. Granulated sulfur -the main commercial type of elemental sulfur -is transported in large quantities both by land and sea and can have a negative impact on the environment. At the moment, the issue of the negative impact of granulated sulfur on the environment has not been fully studied, which determines the relevance of this research. This review article presents the global market of granulated sulfur, paying attention to its safe transport -from the producer to the consumer. The potentially harmful factors of the impact of sulfur handling on elements of the natural environment, such as atmospheric air, water reservoirs, soil and vegetation, were also taken into account.

Drilling muds play the essential role the drilling process as they perform many functions, such as the removing of drill cuttings and controlling well pressure. Water-based drilling muds, through the use of more environmentally friendly additives, can meet increased environmental requirements. Many researchers have studied the effects of different natural materials on drilling mud to find environmentally friendly and effective drilling mud materials. The popularity of using waste materials is mainly due to their cost and favourable environmental impact. Performed literature review showed that the rheological and filtration characteristics of water-based drilling muds are enhanced with the addition of leaves of various plants and trees. This article presents investigations of clay-free drilling mud with the addition of birch and aspen leaf powder. This is relevant in the autumn period, since fallen leaves are solid municipal waste and should be disposed of by removal to landfills. The obtained data indicate the possibility of using leaf powder in the drilling mud composition. Addition of leaf powder to the base mud increases the gel strength and plastic viscosity of the mud. In an extent reduces the yield point and filtration index. Rheological parameters increase by 10-30% and filtration index decreases up to 15-17%.
