Abstract

The article presents the definitions of optimal conditions for the technological process of hydrocarbon emissions utilization for the use of sulfur and oil waste for the production of composite materials in the oil production process. Gas is purified from hydrogen sulfide and carbon dioxide using sorption methods, which are characterized by high absorber pressure (up to 6 MPa) and the absence of oxygen in the gas. Aqueous solutions of ethanolamine are used as absorbents, namely monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA). MEA is widely used due to its high absorption capacity and relatively low cost. However, reagent loss occurs during its regeneration. Hydrogen sulfide and carbon dioxide are typically absorbed at a temperature of 20-4°C, and regeneration is carried out from a saturated solution at 105-13°C. The study results showed that waste is classified according to several key criteria: origin, physical state, hazard level, and potential for further processing. Based on origin, waste from the oil and gas industry is categorized into: industrial; process-related; oil-containing; drilling; chemical; household. To achieve this goal, it is recommended to use sealed equipment, modern oil and gas processing systems, technologies for capturing volatile organic compounds, and automated emission monitoring systems. The application of these technologies makes it possible to significantly reduce the volume of pollutants released into the atmosphere. As a result of the research, possible concentrations of the following harmful substances in the atmospheric air were determined: nitrogen dioxide, nitrogen oxide, ammonia, benzopyrene, diethanolamine, kerosene, acid, sulfuric acid, acetic acid, silicon dioxide, xylene, manganese, copper oxide, mercaptans, sodium carbonate, sulfur oxide, inorganic dust, kitchen aerosol, soot, hydrogen sulfide, lead, carbon monoxide, hydrocarbons, carbon monoxide, fluorine.
