Through the comprehensive use of modern science and technology,thiscenter analyzes and solves all kinds of "soft" and "hard" problems of complex or large systems in energy-intensive industries such as petrochemical, nonferrous metals and metallurgy, and strives to exert the maximum benefits of systematic energy saving to achieve the optimal design, planning, decision-making, control and management of the system. Systematic energy saving has gradually become a powerful tool for upgrading traditional chemical industry and petrochemical industry with modern information technology. Supported by the research platform of Systematic Energy Conservation Technology Research Institute and the Chemical Engineering Department of Tsinghua University, this center is currently working with about 15 enterprises and public institutions such as Sinopec, China National Coal Group and China Chemical Industry Federation to carry out research and results transformation of applied technologies and cutting-edge technologies. We will cooperate with the Department of Environmental Resources of the National Development and Reform Commission, the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information, Shandong Provincial Department of Industry and Information Technology, Shandong Provincial Development and Reform Commission in the field of industrial energy conservation.
