Abstract:

This article examines methods for optimizing the oxidation of petroleum raw materials in the production of bitumen. Technological aspects of the operation of oxidizing columns and tubular reactors are considered, including the modernization of structures, technological parameters of oxidizing columns and oxidation parameters in tubular reactors to increase plant productivity and improve the characteristics of the bitumen obtained. Special attention is paid to an innovative approach – sonochemical activation of raw materials, which allows to reduce the process temperature, shorten the oxidation time and improve environmental performance. The results of mathematical modeling confirming the advantages of ultrasonic exposure are presented. It is shown that the combination of traditional and new methods of regulating oxidation parameters contributes to improving bitumen quality and economic efficiency of production. The practical significance of the work lies in the possibility of applying the proposed solutions in existing production facilities to increase the degree of conversion of raw materials and reduce the residual oxygen content in oxidation gases. The scientific novelty of the study is the development of an integrated approach to optimizing the oxidation process using modern methods of intensification. The results of the study can be used in the modernization of existing installations for the production of oxidized bitumen, which will improve the technical and economic performance of the process and improve the environmental characteristics of production.
