Abstract
In this work, exergy analysis of cumene production plant is carried out in an integrated environment of Aspen Plus and MATLAB. Physical exergy is calculated in Aspen plus V.10 while an interface of MATLAB and Aspen plus was used to calculate chemical exergy of the process. For systematic analysis and comparison, the cumene plant is divided into three sections: preheating section, reaction section and separation section. Then exergy efficiency, irreversibilities, and exergetic improvement potential were calculated. The overall plant exergy efficiency, irreversibility, and improvement potential were 84.93%, 95960.52 kW and 15102.5 kW respectively. The reaction section had the highest exergy efficiency of 87.44%, while the separation section had the lowest exergy efficiency of 58.95%. The analyses performed in this study will provide a basis for optimization of design and operation of the plant.
