Abstract: In this paper, a method for calculating emergys of output streams and inner streams of chemical process system was proposed for the optimal design of the systems.Based on a energy or mass flow diagram, the distributions of material flows and the energy distributing coefficient are determined, and then a tracking method was proposed to calculate the emergys for the complex system by estimating the distributing parameters of input emergy among the inner streams.The proposed method was applied to the emergy analysis of a corn fuel ethanol production process.

Key words: emergy analysis, complex systems, eco-chemical process design
