Energy-saving measures for the operation of industrial furnaces at a gas processing plant

Abstract

THE RELEVANCE. The gas processing industry is quite energy intensive and requires significant energy costs to carry out its activities. Finding ways to improve the energy efficiency of enterprises in this industry is a necessary and urgent task. THE PURPOSE. Identification of opportunities to improve the energy efficiency of the operation of existing industrial furnaces of a gas processing enterprise with the development of energy-saving measures.METHODS. To achieve this goal, a study of existing industrial furnaces of a gas processing enterprise was conducted for the possibility of useful use of low-potential heat of outgoing flue gases. A feasibility study of the proposed energy-saving measures has been carried out.RESULTS. The analysis of the enterprise revealed a low efficiency of technological furnaces. The reasons for the low efficiency are the overestimated excess air coefficient and the high temperature of the exhaust flue gases. The following directions for improving the efficiency of furnaces are proposed: utilization of the thermal energy of flue gases and maintenance of the excess air coefficient at the regulatory level.CONCLUSION. The calculated energy saving potential with a decrease in the temperature of outgoing flue gases to 160 ° C was 82348.8 Gcal, and with a decrease in the excess air coefficient to the standard 5% - 8986 Gcal. In total, this amount will amount to about 23% of the total heat generation by industrial furnaces. The proposed energy-saving measures will make it possible to utilize the thermal energy of flue gases and reduce the excess air coefficient in order to achieve a standard fuel/air ratio. The effect of the proposed measures will amount to 79694 Gcal, which is about 20% of the total heat generation by industrial furnaces.
