ANALYSIS OF GREENHOUSE GAS EMISSIONS INTO THE ATMOSPHERIC AIR BY OIL AND GAS FACILITIES
Keywords:petroleum production, carbon dioxide, concentration, modeling, combustion products
Oil and gas companies account for a significant amount of greenhouse gas emissions. The main task of the environmental policy of oil and gas companies is to ensure efficient operation, which includes reducing environmental risks in the production process. Solving the problems related to environmental protection and improving the quality of its social component is always relevant. The urgency is to reduce the man-made load on the environment by oil and gas companies. The aim of the work was to analyze greenhouse gas emissions into the atmosphere by the oil and gas complex objects. In the course of the research, the following tasks were solved: the process of greenhouse gas dispersion in the atmospheric air during emission from a stationary source was modelled; changes in the concentration of greenhouse gas in the air and the possibility of impact on the health of service personnel were analyzed. The research object was the oil and gas company, the research subject – the assessment of greenhouse gas emissions into the atmosphere by stationary sources.
The choice of carbon dioxide for research was substantiated. The concentrations of carbon dioxide emissions from stationary sources were calculated using the empirical-statistical Gaussian model. The dependence for determining the virtual height of stationary sources was improved. The process of carbon dioxide dispersion during emission from stationary sources was simulated, which would help to determine the change of gas concentration in the atmospheric air on the site and the possibility of impact on the personnel. It was proved that the change in the concentration of carbon dioxide emissions depended on the source height. As the height of the stationary source decreases, the concentration of gas in the air increases; at a distance of 500 m from the sources, the concentration of gas in the air corresponds to the normal background value. Under normal background values of carbon dioxide, the company’s emissions do not pose a threat to personnel health.
