The beneficial using the heat of the exhaust gases of the furnaces of the technological unit for the ethylene oxide production

Abstract

© Published under licence by IOP Publishing Ltd. The solution to the issues of increasing energy efficiency and optimizing the work of enterprises in the petrochemical industry is due to the constant increase in prices for primary energy resources. In this article, the technological site for the production of ethylene oxide, which is characterized by high energy intensity, is considered as an object of study. The largest consumer of energy in this area are technologically furnaces. In the framework of the study, an analysis of the operation of the furnaces was carried out, a balance of the heat-technological flows of the site was compiled, the potential for energy conservation in the utilization of the exhaust gases of the process furnaces was calculated, and the possibility of the beneficial use of the obtained heat was calculated. The economic efficiency and payback period of the proposed method of utilization of flue gases is determined.
