Abstract: In order to meet the requirements of National Development and Reform Commission and the other departments of Chinese goverment on the benchmark value of energy efficiency constraint indicators in key areas, refinery A set energy efficiency improvement strategies by analyzing the energy consumption gap and combining with the enterprise development plan against the energy efficiency leader in the industry and the key energy consumption parameters of the refining enterprises in SINOPEC. The strategy was formulated at three levels,i.e. energy consumption planning, energy integration and unit strengthening of the whole plant. The theory of Energy Three-Link was applied, the gap was analyzed by benchmarking, and various energy efficiency improvement technologies were adopted. Several measures for improving energy efficiency were formulated from the aspects of strengthening energy-saving management, optimizing production operation, optimizing production process, improving production technology, improving efficiency of production equipment, and optimizing utilities, etc. It was expected to achieve the goal of energy efficiency constraint benchmark value, and help enterprises to achieve decarbonization goal.

Key words: energy efficiency constraints, energy consumption per unit energy factor, oil refining unit, energy efficiency benchmark
