LUO Yiqing, HU Zunyan, YUAN Xigang. Method for calculating stream emergy in complex chemical process systems[J]. CIESC Journal, 2013, (1): 311-317.DOI: 10.3969/j.issn.0438-1157.2013.01.035.
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.
