Abstarct: Abstract In this study, the use of solar energy as a clean and available source in the cement factory was investigated, which is one of the most energy consuming and also the most polluting industries created by mankind. The cement industry is one of the most consuming industries and also the second producer of carbon dioxide by humans in the world, 5 to 6% of all greenhouse gases produced in industries by humans are produced in this sector. Also, the use of low temperature waste heat in the cooler of the cement factory for power generation was studied by the Kalina cycle. For this purpose, the simulation of the cement production process was carried out in ASPEN HYSYS software, which is an efficient software for simulating chemical processes. The amount of thermal energy needed to perform the calcination process, which accounts for 60% of the energy consumption in the entire cement production process, was calculated. In EES software, the code of the solar sector as well as the storage was developed. According to the thermal energy needed to perform the calcination process, the mirror surface needed to absorb solar heat and transfer it to the heat transfer fluid, which is molten salt, was calculated. This heat was also transferred to the air, which is the carrier of final thermal energy to the process, and the flow rate and temperature of this fluid were calculated. The waste heat in the cooler of the cement factory was introduced to the Kalina cycle to calculate the electric power produced in this power generation cycle. baxsed on the results, using this method, power equivalent to 868.7 kW can be produced using a waste heat source. The area of heliostatic mirrors needed to supply the thermal energy needed to perform the calcination reaction was calculated to be 35.6 hectares. The energy and exergy efficiency of the solar sector were calculated as 46.74 and 36.06%, respectively. The most exergy destruction occurs in thermal storage.
