Abstract: At present, China is vigorously advocating the implementation of energy conservation and emission reduction strategy, which requires all walks of life to form a good awareness of energy conservation. As an enterprise type with large energy consumption, oil refining and chemical enterprises need to pay attention to the implementation of the requirements of energy conservation and consumption reduction, actively use various energy conservation and consumption reduction technologies and make rational use of all kinds of energy. This paper analyzes the application status of energy-saving and consumption reduction technology in oil refining and chemical enterprises, and discusses the application mode of energy-saving and consumption reduction technology, in order to provide reference for the production activities of oil refining and chemical enterprises.
