Abstract:

Improving the efficiency of oil production, refining and transportation processes directly depends on accurate knowledge of its thermodynamic properties. The single evaporation curve is a key parameter that determines the behavior of oil at various temperatures and pressures. The relevance of this work is due to the need to refine and detail data on single evaporation curves for Gubkin oil using publicly available data, which contributes to the development and improvement of technological processes. The purpose of the study was to construct curves for Gubkin oil and its fractions based on data from the USSR Petroleum Collection, Volume 4, to analyze the effect of fractional composition on thermodynamic behavior. The research methodology was based on the analysis and processing of data from the collection, including information on the fractional composition of Gubkin oil and its physico-chemical properties. The data was used to construct curves using appropriate thermodynamic models and correlations. As a result of the work, single evaporation curves were constructed for Gubkin oil and its individual fractions. The analysis of the obtained graphs made it possible to identify patterns in the change of thermodynamic behavior depending on the fractional composition. It has been established how differences in the composition of fractions affect the shape and position of single evaporation curves. The conclusions of the study demonstrate the possibility of using data from the USSR oil collection to construct reliable curves of single evaporation of Gubkin oil and its fractions. The results obtained make it possible to more accurately predict the behavior of oil in various operating conditions and optimize the technological processes associated with its production, processing and transportation. The work highlights the importance of analyzing archived data for solving urgent problems in the oil and gas industry.
