GE plans to set up an Industrial Internet Centre of Excellence at IIT Madras, to develop power intensive applications with the first focus on rolling out a Digital Twin of an Aluminium Smelter. Aluminium smelters are essentially refineries for extracting aluminum from aluminium oxide, separating the aluminium from oxygen through a chemical reaction. Through the new Centre, GE and IIT Madras will create a Digital Twin of a smelter. The Twin is a living digital model that will continuously generate new data and insights about the smelter that allows operators to run them more efficiently. For the aluminium smelter industry, the net gains through such productivity enhancement are valued at between $50 to 150 mn annually.
