Most of the waste heat from cement plants is discharged along with the exhaust gas. The temperature of the flue gas leaving the preheater is about 330°C. This heat could be reused by a waste heat recovery system for power generation. Technologies for waste heat power stations have been reported by many researchers, and there are many different processes for different conditions. Sheinbaum and Ozawa [
3] reported that using the waste heat to improve the cement plant process, increased the energy utilization efficiency to 28% and reduced the CO
2 emissions by 17%. After studying the cement industry in China, Liu et al. [
4] reported that energy efficiency can be improved 10% to 30% by retrofitting the cement process. Özdoğan and Arikol [
5] stated that using waste heat will increase the efficiencies according to the first and second laws of thermodynamics. Hasanbeigi et al. [
6] proposed some technologies to improve the process and reported an average technical potential primary energy savings of 23% could be realized at best practical levels. Barker et al. [
7] and Hassan [
8] studied the feasibility of CO
2 capture by doing simulations of monoethanolamine (MEA) based processes for CO
2 removal in cement plants. However, the integration of waste heat recovery with CO
2 capture has not been mentioned in the literature.
