Abstract :
The technological progress in the cement industry has allowed for the construction of large capacity plants with several new kilns producing up to 10000 metric tons per day (t/d) of clinker. These super plants have imposed new constraints and requirements on the process control systems. This paper sets out to present the consequences for the control system, plant optimization and quality control through the study of three different projects: Siam City Cement Co. (SCCC), Kiln 5, Thailand, 10000 t/d, Asea Brown Boveri distributed control platform; PT Semen Gresik, Tuban, Indonesia, 7500 t/d, Bailey distributed control platform; PT Semen Tonasa, Tonasa IV, Indonesia, 7500 t/d, FLSA Summit series/Allen-Bradley PLC based control platform
