Line 1, commissioned in 2001, features control system, instrumentation, drives and motors from ABB. Incorporating 150 transmitters (Profibus PA) to measure pressure and temperature at critical points down the line, the complete cement plant solution is comprised of an electrical power control and automation package.
In 2010, the plant was enhanced with the Expert Optimizer (EO), a thin client-based graphical engineering and programming tool that controls and optimizes the kiln and mills.
For Line 2, commissioned in 2011, Chettinad again contracted ABB to supply a complete, IEC 61850
-compliant electrical power distribution and automation package. The contract comprises upgrading Line 1’s control system to ABB’s System 800xA including the latest human machine interface (HMI). Drives, motors and 150 transmitters were also supplied by ABB. In addition, the new ABB Advance Optima 2020 continuous gas analyzers were used to help with product quality and nitrogen oxides (NOx), sulfur oxides (SOx) compliance.
This plant features Knowledge Manager (KM), an ABB solution for production and quality management specifically for the cement and mineral processing industry. ABB leveraged its know-how and long experience in other deliveries to Chettinad. For example, for Chettinad’s 5,000TPD Ariyalur cement plant, ABB supplied the electrical power distribution and automation package (Line 1), and a distributed control system (DCS) (Line 2).
