Promising directions for the use of heat from low-potential sources of chemical production

Abstract

THE PURPOSE. Development of promising directions for improving the technology of an oil refinery (refinery) based on the use of heat from low-temperature sources of the primary oil distillation system.METHODS. The analysis of the technological scheme of the refinery carried out, in order to identify the most energy-intensive system, while using the methods of analytical and thermodynamic analysis. The analysis of energy use in the circuit of an electric desalination plant (EDP) is carried out according on the basis of the data of the technological regulations of the existing EDP-AVT-7. The assessment of the feasibility of the proposed directions and developed solutions was carried out on the basis of the methods of technical, economic and environmental analysis.RESULTS. This article shows the relevance of the problem and substantiates the importance of its consideration for improving energy and environmental efficiency. Based on a common scheme for the primary processing of crude oil, it is noted that this technology has significant energy saving potential. It is proposed to implement promising directions for the rational use of heat, and a modernization solution is presented aimed at improving the technological elements of the EDP-AVT-7 circuit based on the heat recovery of the hydrocarbon vapor-gas mixture.CONCLUSION. The proposed directions and developed measures for the use of heat from low-grade sources in the refinery scheme show their promise due to a significant reduction in technological energy losses, a reduction in fuel consumption and an increase in the efficiency of its use, which, in general, will positively affect the economic and environmental situation in the region.
