This paper provides an overview of the adsorption of petroleum products, focusing on various aspects such as adsorbent types, mechanisms of adsorption, factors influencing efficiency, kinetics, equilibrium, practical applications, and environmental implications. It explores the properties and characteristics of adsorbents, including activated carbon, zeolites, clay minerals, silica gel, and others, highlighting their interaction with petroleum products. The article delves into the theories and mechanisms governing the adsorption process, discussing physical and chemical adsorption as well as the role of forces like van der Waals, hydrogen bonding, and electrostatic interactions. The results of experimental investigations were conducted to evaluate the adsorption capacities of various adsorbents for petroleum products. The adsorption performance, kinetics, and equilibrium behavior of different adsorbents were analyzed, providing insights into their effectiveness in removing petroleum contaminants from aqueous solutions. The adsorption kinetics and equilibrium studies were explored through mathematical models like Langmuir and Freundlich isotherms. The practical applications of adsorption in the petroleum industry were discussed, including removing pollutants from wastewater, gas and diesel purification, and desulfurization. The environmental implications of adsorption technology in mitigating oil spills and reducing petroleum-related pollution were addressed. The conclusion emphasizes the significance of these studies in enhancing understanding, developing efficient solutions, and addressing environmental challenges associated with the petroleum industry. Ongoing research in this field aims to further improve adsorption processes for a more effective and sustainable approach.

The level of phytotoxicity of the soil samples artificially contaminated with the aviation kerosene was determined in the work. The dependences of the growth characteristics of the plant test system (flax) on the excess of the approximate permissible concentrations (APC) of the oil product concentration in the soil were identified. The change in the mass of raw material depending on the level of aviation kerosene contamination of soil samples was determined. A decrease in the plant growth activity with an increase in the content of aviation fuel in the soil was established. It was found that there is a hormesis effect at certain concentrations of aviation kerosene in the soil. The comparison of the concentration dependences of the action of petroleum products on the growth rates of seedlings and their dependence on the distance to the source of pollution allowed in the latter case to conduct a kind of “dosimetry” on exposure concentrations when the petroleum product concentration was not determined.

Well drilling involves the formation of the bore mud in a form of drilled solids with waste drilling mud, containing oil products in its structure. Nowadays, the widely used methods such as thermal, physical and biological ones cannot be considered as complex approach to the solution of the problem of the oil refinery wastes handling. Introduction of the peat and natural mineral sorbents into the bore mud allows decreasing the residual content of the oil products, and, thus, decreasing the level of negative influence on the environment. On the basis of the conducted studies, it was revealed that different norms of sorbents and peat introduction into the bore mud decreased the concentration of oil products equally well; therefore, the recommended dosage of sorbents and peat at the low initial values of oil products can be 3–5%. When introducing glauconite in a form of flour and grain there it noted that the size of grain particles of the sorbent influenced insignificantly the decrease of oil products concentration in the bore mud. The use of natural mineral sorbents and peat favorably influences the development of plants. At the same time, the formation of viable phytocenosis with high value of phytomass of vegetative over-ground sprouts takes place.

In the course of the study, the following tasks were solved: determining the level of oil products and their spatial distribution in surface waters and bottom sediments of the Tura River, studying the features of the accumulation of oil products in bottom sediments in different sections of the Tura River, as well as the effect of storm and melt water contaminated with oil products within the coastal boundaries on the general background of pollution, calculated by the approximation method the distance at which the maximum permissible concentration for the Tura River would be reached, gave recommendations on the preservation of the object under study. The research was carried out in the laboratory of the Tyumen Industrial University. The analysis of samples for the content of oil products was carried out by the fluorometric method on a fluid analyzer “Fluorat-02–2M”. The results of the study indicate the need to monitor surface waters and toughly respond to insufficient compliance with the standards for the protection of surface waters and bottom sediments within the city of Tyumen.

The water resources are the main component of technological processes occurring in industry; therefore, increasing the level of environmental safety, in particular, wastewater treatment without adverse impact on the environment and human health is relevant. The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company’s activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. The studies conducted with the aim of determining the motor transport enterprise sewage composition revealed an excessive content of polluting chemical substances, namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of using carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of wastewater of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing the environmental fees and penalties.

Nowadays one of the most important problems in environmental protection is the pollution of groundwater by derivative products of oil. A common case of the infiltration of the oil derivative products to the ground water system is mainly connected with accidental oil spills in various types of environmental conditions. In this case we encounter numerous types of problems connected especially with the pollution in: 1) aeration zones, 2) saturation zones. The first step is a conceptual model for the proper recognition of the type and scale of the problem. After making a conceptual model it is possible to take a preliminary decision to recognize what sort of pollution is the source of the environmental problem. A study example describes modeling of free products of oil (LNAPL) floating on the groundwater table using MARS (Multiple Areal Remediation Simulator). The multiphase model was made on the basis of theoretical model concepts. In the modeling the recovery and migration of LNAPL are simulated, and the recoverable and residual spill volumes of derivate products of oil are estimated. Modeling indicates the best location of the remediation system and the pumping wells. Additionally, modelling can be applied to manage the remediation system for improving the efficiency and for decreasing the catchment area of piezometers and wells.
