Abstract:

Petrochemical industry is a high energy consumption area, its development is being restricted by the shortage of resources. Energy management system based on the deep integration of informatization and industrialization can greatly improve the quantitative management abilities of energy and has a great prospect on supporting an enterprise to optimize its energy consumption. Sinopec achieves satisfactory results by constructing energy management system based on information technology. The overall planning of energy optimization system has been proposed in this paper, the functions of this system have been designed by analyzing petrochemical businesses. Moreover, the steam power system has been taken as an example to illustrate the business functions of the optimization system. The specific description of energy optimization process of the system has been demonstrated in the aspects of the construction of mechanism factory model, data inspection, data correction, online energy optimization and online model regulation. Finally, the application benefits of three pilot enterprises have been analyzed. Especially, this can be regarded as a reference provided for petrochemical enterprises to promote energy conservation in their informatization construction process.
