Methodology 2.1 Cement production simulation Aspen HYSYS 8.8 was used for the steady-state simulation of the integrated process flow sheet for the cement production [44]. Within the simulation environ- ment, topological optimization (proper arrangement of equipment) was done to enable very high energy savings or optimization.

In this kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water.

THE MANUFACTURING PROCESS. Portland cement is made by heating raw materials rich in oxides of silicon, calcium, aluminium and iron to temperatures of around 1200 - 1400oC. The chemical reactions that occur within the partially molten mass result from the formation of the four main cement materials (Table 1).

In this study the process flow diagram for the cement production was simulated using Aspen HYSYS 8.8 software to achieve high energy optimization and optimum cement flow rate by varying the flow rate of calcium oxide and silica in the clinker feed.

Ans: It is a hydraulic cement which was patented in 1824 by Joseph Aspidin. It is produced by heating a mixture of limestone and clay in a kiln to a high temperature of 1,450 °C. Then the clinker is ground to a fine powder which is known as Portland Cement. It has a wide range of applications in construction work.
