Multi-objective optimization and synthesis of energy/mass coupled cascade utilization network

Abstract：Due to the different grade of energy and mass， the cascade utilization of energy and mass is the core approach to reach high efficiency， energy saving and emission reduction. This subject aims to coordinate the different functionalities and objectives for energy and mass transferring system via thermodynamic analysis. We will explore the relationship between the network topology and different functionalities and objectives and identify the system bottleneck. The theory and approach on the multi-objective optimization of energy/mass coupled cascade utilization network will be built and the way of resource utilization optimization would also be investigated. In addition， the research results would be applied in the typical chemical process for olefin and polyolefin.

Keywords：Energy/mass transferring network； coupling； multiple-objective； bottleneck； optimization
