Abstract:

Energy conservation, emission reduction, and green development are the requirements for high quality and sustainable economic development in China. Despite the rapid development of new energy, there are still limitations in its application scenarios that need to be overcome urgently. Fossil fuels still play an important role in the global industrial energy supply. The petrochemical industry is a major energy consumer and carbon emitter in the industrial sector, with heating furnaces accounting for the largest proportion of operating costs. Therefore, achieving efficient utilization of fossil fuels through technological progress in the heating furnace field is the most effective way to promote energy conservation and emission reduction in the petrochemical industry. This article discusses the improvement of energy conservation and emission reduction capabilities in petrochemical enterprises through technological progress in four aspects: enhancing radiation heat transfer performance of heating furnaces, efficient combustion equipment and combustion technology, combustion system control technology, and deep utilization technology of flue gas waste heat. It also summarizes the current status and characteristics of research and technology, and proposes that one or more technology combinations should be applied according to the characteristics of heating furnaces in different process units, in order to better achieve energy-saving and emission reduction goals.
