Abstract: Ammonia alcohol cogeneration is one of the pillar categories in chemical industry，the value of flow calculations and analysis has important practical significance for the improvement of existing production processes and environment protection. This article adopts Japanese LIME evaluation system to convert the environmental damage caused by ammonia waste (SO2，CO2，NH3，etc.) to the monetary damage value. At first，the loss was identified by the calculation of value stream to make the hidden losses apparent. According to resource flow consumption and the principle of technical and economic feasibility，by the comprehensive utilization of dualistic evaluation composed of internal cost loss based on accounting principles and the cost of environmental damage based on the assessed monetary value of damage by pollutants，different improvement programs were proposed. Then “economic- environmental” cost-effectiveness comparative assessment was implemented. As indicators of circular economy performance evaluation and basis for improving production processes，resource value flow accounting system can provide a set of analysis，diagnosis and evaluation methods for circular economy of the ammonia industrial development.
