Abstract

In order to comprehensively assess the resource utilization of a process system and its influence on the environment, the application range of the traditional exergy analysis was expanded in this paper to include the pollution degree of the discharged wastes to the environment. So technology indexes can be obtained to comprehensively assess the resource utilization and the environment impact of a process system. The harm coefficient and effect coefficient were introduced to concern the different harm to the environment of the different wastes and the pollution effect relative to resource waste by environment. The determination method of the harm coefficient and effect coefficient was discussed. Two suspension polymerization flows of polyvinyl chloride were calculated with this method. The results show that the method can comprehensively assess the resource utilization and the environment impact of the chemical process system by comparing and analyzing.
