Extended Exergy Accounting For Energy Consumption and CO2 Emissions of Cement Industry-A Basic Framework

Owing to the intensive energy consumption and CO2 emissions of cement production process, attention has been focused on exploring an integrated metric for mitigation potential. Exergy is thereby raised to analyze the system operation efficiency and environmental cost. In this paper, exergetic efficiency and CO2 emission targeted at a typical cement production line are examined in detail with key factors of mitigation being identified. Moreover, the future emission trends are simulated based on dynamic prediction with different optimization scenarios in view of current mitigation targets. Finally, some preliminary results are presented.
