摘要
针对复杂过程系统的生态化设计,研究系统内部及输出流股能值的计算策略和方法。基于系统能量或质量流程图,确定系统内外的能流、物流的分布和能量分配系数,通过建立复杂系统能值计算的循迹法,确定系统各种输入能值在系统内的分配,解决复杂系统内部联结各单元的流股能值准确计算问题。基于该方法,对玉米燃料乙醇生产过程系统进行了能值分析和评价。
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.
