Metso has developed its own advanced modular precursor (pCAM) plant process solution based on Metso’s existing technologies, allowing cost-effective and sustainable pCAM production that meets a continuously increasing need for battery material. Modularity and new all-in-one precipitation reactor solution will add the needed flexibility to increase production capacity step by step and produce different types of co-precipitated precursor chemistries while realizing cost-savings in start-up or expansion phases. The efficiency of the pCAM process will increase through the use of Metso online analyzers. Online analyzers can be used, for example, to control metal concentrations of the feed solution or to measure the particle size of precipitated precursor. When on-line analyzers are connected to the process, the need for laboratory analysis decreases and more real-time data becomes available for process control. Automated process parameter control can be built based on the analysis results because on-line analysis enables fast reactions to changes in the metallurgical behavior of the process, thereby increasing production rate and decreasing downtime and the amount of off-spec material. The benefits of the modular Metso pCAM plant solution include (1) the precipitation process can be operated in several modes (batch, semi-batch, or continuous), (2) on-line particle size and metal solution analyzers control precipitation, and (3) advanced automation (digital solution) can automatically predict and control process parameters.
