The Metso:Outotec Calciner Optimizer is a digital solution to actively control and optimize Alumina Calcination plants. It is today in continuous, close to 100% availability, operation at Companhia Brasileira de Alumínio (CBA).
The paper covers the architecture of the digital solution, the impact on CBA Calciner operation and how detailed process understanding is integrated in a digital form into the daily process operation. The close cooperation between CBA process experts and Metso Outotec digital and process experts forms the basis of a successful implementation. Results are shown and discussed in this paper, proving significant energy savings when operating the plant with the Optimizer.
Using the Optimizer provided a reduction in specific fuel gas consumption and greenhouse gas emissions. Further, the fluid bed calcination process know-how, combined with the advanced digital Optimizer solution, represents an enabler for future operational improvements.
