Assessment of the industrial emissions impact on the quality of atmospheric air in the Burlin district of West Kazakhstan region DEVELOPMENT

Abstract

The article is devoted to the study of air pollution in the Burlin district of the West Kazakhstan region, where one of the main sources of air pollution is the Karachagan oil and gas condensate field, the main feature of which is the high content of hydrogen sulfide in natural gas from 4 to 4.3%. The analysis showed that the atmospheric air state in the specified area is determined by the characteristics of harmful emissions sources, composition, volumes of pollutant emissions and climatic characteristics of the territory, which determine the conditions for the polluting components dispersion. The qualitative and quantitative characteristics of the chemical composition of the atmospheric air in the study area, as well as the features of their changes over the years end climatic seasons, are largely determined by emissions of nitrogen oxides, carbon, sulfur dioxide, hydrogen sulfide, volatile organic compounds and inorganic dust into the atmosphere by oil and gas facilities. The anthropogenic influence of industry in this area is also evidenced by the calculated value of the integral coefficient of air pollution. At the same time, industrial enterprises, having increased the anthropogenic impact on the environment, have the ability to prevent negative environmental consequences. The system of industrial environmental control of the chemical composition of industrial emissions at the Karachagnak field facilities is carried out on an ongoing basis. The analysis showed that a reduction in emissions and, accordingly, a reduction in ground-level concentrations of air pollutants at the Karachagnak field facilities is ensured by a whole range of technological and organizational measures, among which the technology of high-pressure gas reinjection deserves special attention. It necessitates the need to carry out systematic work to study the ecological state of the territory of the Karachagnak field, using not only ground-based research methods, but also modern geoinformation and aerospace technologies that make it possible to dynamically assess the changes taking place, conduct a geo-ecological assessment and make a forecast for the development of the environmental situation in this area. territories. The work carried out contributes to further analysis of the regional assessment of the environmental state of the atmosphere of large industrial centers.
