Design and optimization of total site energy systems for chemical plants

Abstract

Total site design technique is developed for the optimal synthesis of whole energy systems that consist of the heat recovery system and the steam power system. In the design of a total process system, heat exchange between a heat recovery network (HEN) and a steam distribution network (SDN) is available for obtaining the better energy utilization. Specifically, the heat flow distribution between total sites is considered to enhance the performance of whole systems. A systematic energy management is fulfilled with the proposed integrated SDN-HEN model, where the allocation of the energy flow is optimized. Case study is presented to demonstrate the feasibility and benefits of the proposed approach. Copyright ? 2011,.
