【 摘 要 】

This study investigates the appropriateness of exergy calculation using Aspen Plus Process Simulator which has a robust data library and powerful engineering calculation capabilities. The simulator was used for the thermodynamic performance of a raw mill (RM) and raw materials preparation unit in a cement plant in Nigeria using actual operating data. The raw mill has a capacity of 240,000 kilogram-material per hour. Also, both exergy and exergetic efficiency of raw mills from three literature sources were investigated and compared with the simulation results from Aspen Plus process model. The results were subjected to statistical analysis using ANOVA. The exergy efficiency for the raw mill studied using Aspen plus simulator modelling technique was found to be 21.4%. It was found that the difference in exergy efficiencies of the simulation results of the three-literature data vary within ±2.5% of the published results. The present method using the Aspen plus simulator is suggested as a useful tool in making informed decisions for developing energy policies and exergy utilization, providing energy conservation measures in improving the efficiency of the system.
