EFFECTIVENESS ESTIMATION OF AN ASSOCIATED PETROLEUM GAS UTILIZATION PROJECT

One of the current environmental and economic problems of the oil extraction process is the implementation of projects that result in an increase in the utilization rate of associated petroleum gas. In order to make a decision on the financial feasibility of implementing environmental protection measures, it is necessary to calculate their environmental and economic efficiency, which is the goal of this work.The set goal necessitated the need to, firstly, analyze the current practice of using associated petroleum gas based on the materials of the Volzhskaya Neftyanaya Kompaniya JSC. Secondly, calculate the specific weights of the emitted pollutants that result from the utilization and combustion of associated petroleum gas (while the authors recommended taking into account the coefficient of the relative ecological and economic hazard of each specific pollutant). Thirdly, determine the structure of the emitted harmful substances after the implementation of a project to improve an autonomous gas-piston power complex designed for generating electricity. The fourth task set by the authors was to assess the prevented economic damage from reducing air pollution as a result of implementing a project to improve the use of associated petroleum gas. The fifth task is to calculate static indicators of economic efficiency.The authors have achieved their research objectives, namely, they have presented the methods of using associated petroleum gas based on the company's existing recycling practices and design solutions. The application of the relative environmental and economic hazard coefficient in the vertical analysis of the quantitative composition of harmful substances emitted into the atmosphere has revealed changes in the actual structure of air pollutants. The presented environmental indicators of gas-piston engine operation have determined the direction for improving the process of associated petroleum gas recycling, which should involve the modernization of an autonomous gas-piston power plant used for generating electricity.The authors calculated the amount of economic damage prevented by reducing emissions of harmful substances. Using the authors' methodology for assessing the effectiveness of atmospheric protection measures [1], they calculated the economic efficiency indicators for the project discussed in the paper.
