Assessment of entropy-based approach for the environmental impact of the cooling process in clinker production

Abstract

Cement clinker production is an energy-intensive process that results in significant environmental pollution. This study analyses the environmental effects and exergy performance of the cooling process in dry-type cement production using an entropy-based approach. The process’ useful exergy efficiency was found to be 17.4%, while the waste-induced exergy was 51.1%. The useful exergy EPI value was 0.685, with a development rate of 65.87% and an energy efficiency rate of 56.52%. The process has an energy efficiency rate of 27.18%. Based on the results, measures to improve environmental sustainability by reducing entropy production in the cooling process were recommended.
