Abstract:

this paper discusses computational methods for determining the physico-chemical properties and composition of oils and petroleum products, the example of the Romashkin oil. The relevance of the study is due to the need for accurate analysis and assessment of the quality of hydrocarbon raw materials for its effective processing and use. In the course of the work, the main physico-chemical characteristics such as density, viscosity, temperature dependences and composition of hydrocarbons are presented. Special attention is paid to methods that allow the calculation of properties based on available data on the composition of oil and its fractional composition. Both traditional approaches and modern computer models are used, which makes it possible to increase the accuracy of forecasting. The work is aimed at improving methods for assessing the physico-chemical properties of oils, which can help optimize their processing processes and increase the efficiency of field operation in difficult climatic conditions. The calculations were performed using a well-known algorithm using the Mathcad program.

Keywords: molecular weight, Compressibility, Fraction, Density, oil
