Energy analysis and management method of complex chemical processes based on index decomposition analysis

Energy and management of complex chemical processes play a crucial role in the sustainable development procedure. In order to analyze the effect of the technology, management level, and production structure having on energy efficiency, we put forward an energy analysis and management method based on index decomposition analysis (IDA). The proposed method can reflect the impact of energy usage by integrating the level of energy activity, energy hierarchy and energy intensity effectively. Meanwhile, energy efficiency improvement, energy consumption reduction and energy-savings can be visually disCovered by the proposed method. Finally, the proposed method is applied for energy management and conservation practices of the ethylene production process. The demonstration analysis of ethylene production has verified the practicality of the proposed method. Moreover, we can propose corresponding improvement for the ethylene production.
